Overview
SilkPerformer offers recording and replay support for the load testing and
functional testing of SAP® systems that use the SAPGUI Scripting interface.
SilkPerformer’s unique content verification feature enables you to verify
application functionality even under real-world load conditions—and thereby
intercept application errors that occur only under load.
Test scripts created for functional testing can be reused for load testing purposes,
without requiring any changes.
Together with its outstanding support for the load testing of Web applications,
SilkPerformer supports load and functional testing of SAP R/3 4.6C, SAP R/3
Enterprise (4.7), and mySAP Business Suite (and higher) via SAPGUI Client
6.2 (and higher) for Windows and HTML, as well as with mySAP Enterprise
Portal.
Note This tutorial offers only a brief overview of the functionality
that is available with SilkPerformer and TrueLog Explorer. Please
see the SilkPerformer User Guide and the TrueLog Explorer User
Guide for full details of available functionality.

SilkPerformer SAPGUI Tutorial 1

INTRODUCTION
Overview

Scripting In addition to a powerful BDL API for SAP that enables programmers to
effectively customize SAP test scripts, SilkPerformer 2006 R2 also provides
TrueLog technology for SAP—offering easy visual script analysis and
customization.
TrueLogs provide complete visual representation of all actions and results that
are generated by test scripts. Screenshots are captured during test runs and
details regarding all visible GUI controls are logged. Using TrueLog Explorer’s
intuitive point-and-click interface, you can visually customize all user-input data
and create content verification checks for return data. Simply select the input
values that you wish to customize, or the result values that you wish to verify,
and then choose any appropriate parsing, parameterization, or verification
functions. All customization and verification functions are then automatically
generated and inserted into your BDL script. No manual scripting is required.
Functional testing SilkPerformer provides functional and load testing with a single tool. Simply
reuse your scripts as both functional and load testing scripts using the same
script API.
Front-end analysis Using SilkPerformer’s TrueLog On Error functionality for SAP, you can
visually inspect the actions of SAP virtual users and SAP system responses that
result in error conditions. In this way, you can visually analyze error conditions
from the virtual-user perspective (the front-end).
SAP monitoring SilkPerformer offers five Performance Explorer monitors that enable you to
query SAP server-side performance values.
SAP eCATT SAP’s eCATT (Extended Computer Aided Test Tool) facility allows you to create
test scripts in SAP using the scripting language of your choice. eCATT allows
you to use external test tools such as SilkPerformer while utilizing eCATT as a
repository for your test scripts. See “SAP eCATT Integration With
SilkPerformer” for details.
Enabling SAP SAPGUI record/replay technology is based on the SAPGUI Scripting API,
scripting which must be enabled on both the server and client side.
The SAPGUI Scripting API is not available in all SAPGUI client versions;
therefore you must confirm your patch level. Please refer to Enable SAP
Scripting in SilkPerformer Online Help for details.
Checking SAP patch SAPGUI Scripting is not supported by all versions of SAP. Therefore it is
level necessary that you confirm that your installation offers this support. You can do
this by checking your current patch level. The patch level needs to be at least 44.
Procedure To confirm server patch level:
1 Launch the SAPGUI logon window (Start/Programs/SAP Front End/
SAPLogon) and choose the About SAP Logon menu item from the
window menu.

INTRODUCTION
Overview

2 The SAP version information dialog box appears. Confirm that the patch
level is at least 44. It is however recommended that you use patch level
50 or higher as some memory related issues have been found with
previous patches.
Profile settings SilkPerformer SAP GUI support is configurable via SilkPerformer profile
settings.
Recording settings The following recording settings can be configured on the profile settings’
Recording tab:
Script logon as single function
When enabled, the logon procedure is scripted as a SapGuiLogon API call.
When disabled, multiple API calls (e.g., setting username, setting password,
hitting ENTER are scripted).
Script low level functions
Rather than scripting high-level API functions (e.g., SapGuiSetText) low-level
API functions are scripted (e.g., SapGuiInvokeMethod, SapGuiSetProperty).
Script timers
Most SAPGUI API functions take an optional timer parameter. When such a
parameter is defined, measures are generated during replay. When this option is
enabled, the SAPGUI recorder automatically scripts appropriate timer names for
each function.
Attach to existing SAP session
When enabled, the SAPGUI recorder attaches to an existing SAPGUI session
without recording the SapGuiOpenConnection statement.
Record window title verification
When enabled, the SAPGUI recorder scripts SapGuiSetActiveWindow with the
window title so that the title can later be verified during replay.
Common Settings
The following settings are common to both recording and replay.
Log level
Defines the logging level. For troubleshooting, Debug should be used.
Otherwise Normal should be used. When running large load tests, logging can
be Disabled to reduce memory consumption.
Capture screenshots
When enabled, screenshots are captured for each new window that is activated.
This option is only available when Show SAP GUI during replay is enabled
during script replay.
Capture screenshots for every action
When enabled, screenshots are captured for each user action that causes a
round-trip to the SAP server. This option is only available when Capture
screenshots is enabled.


INTRODUCTION
Overview

Log control information in TrueLog
When enabled, control information for each control on the active window is
logged to the TrueLog. This allows you to use TrueLog Explorer’s
customization feature. This option should be disabled when running load tests as
it consumes additional resources.
Log control information on error
When enabled, control information for each control on the active window is
logged to the TrueLog when errors occur during replay. This allows you to
troubleshoot replay problems by capturing the current state of all controls on the
screen when errors occur. It is recommended that you use this option during load
tests rather then Log control information in TrueLog, which is resource
intensive.
Highlight controls (replay only)
With this setting, controls that are accessed during replay by any API call will be
highlighted on the SAPGUI Client. This option is only valid when Show SAP
GUI during replay is enabled.
Replay settings The following replay settings can be set on the profile settings’ Replay tab:
Replay timeout
Defines timeout during replay. When there is no response from the server within
this timeout period, an error is thrown.
Show SAP GUI during replay
When enabled, the SAP GUI client is shown during replay. This option can only
be used for TryScripts. By default, replay for load tests is GUI-less.
Enable client-side scripting
SAPGUI Scripting must be enabled on each client machine via the Options
menu of the SAPGUI client application. When running a load test on multiple
agents, this setting must be changed manually on each machine before the load
test begins. By enabling this option, SilkPerformer changes this setting
automatically on each agent before starting load tests.
Use new SAP Visual Design
SAPGUI can be run in one of two visual modes: original design or new design
mode. This setting can be changed via the SAP Configuration Tool. By
enabling/disabling this option, SilkPerformer performs these changes
automatically before starting load tests. This option allows you to compare
resource consumption between the old and new visual designs. The measure tab
contains settings for replay measurement.
You can either enable all timers for all control types, or select only those timers
that are of interest to you. Timers are only created for those method calls that
have the optional timer parameter specified.
For a description of these timers, please refer to SAP Results in SilkPerformer
Online Help.

a Recording SAPGUI Test
Scripts

Introduction This chapter explains how to generate a SAPGUI test script by recording a
SAPGUI application and how to analyze a replayed test script via a TryScript
run.
What you will learn This chapter contains the following sections:

Section Page
Overview 7
Generating Test Scripts 7
Exploring Recorded Scripts 17

Overview
SilkPerformer offers record and replay support for the load testing and
functional testing of SAP systems that use the SAPGUI Scripting interface.
This chapter shows you how to generate a test script by recording a SAPGUI
application and then how to analyze the resultant test script by replaying it in a
TryScript run.

Generating Test Scripts
Procedure To generate a test script by recording a SAPGUI application
session:
1 Click SilkPerformer’s Outline Project button to create a new project.


1 RECORDING SAPGUI TEST SCRIPTS

2 Enter a Project name and Project description.
3 Select ERP/CRMSAPSAPGUI as the Application type.
4 Click OK.

5 Click the Model Script button on the Workflow Bar.
6 If not selected already, select the Record radio button to record an
application session.
7 The SAPGUI Application Profile is preselected. If SAPGUI does not
appear in the Application profile field, you do not have a SAPGUI client
installed on your computer.
Note If you do not have a SAPGUI client installed, install SAPGUI
Client 620 or 640 with the latest patch levels before creating a new
SilkPerformer project.
If SAPGUI is still not listed in the Application profile field, you need to
create the application profile for saplogon.exe. In SilkPerformer, open
the System Settings dialog and select the Recorder icon on the left. Under
the Application Profiles tab, add a new Application profile called
SAPGUI and specify your saplogon.exe as executable in the Application
path field. Specify Custom Application for the Application type and
check the SAPGUI protocol checkbox. Click the OK button to confirm
your settings and close the System Settings dialog.



8 Click OK to launch saplogon.exe.

9 Specify the SAP application server that is to be tested (this tutorial
illustrates the testing of a SAP calendar application).

Note On multi-lingual SAP systems it is recommended that you
specify the language that is to be used by the SAPGUI client before
recording begins. This prevents possible language differences
between recording and replay (i.e., different languages may be
selected by different load test agents, which will lead to Window
Title Verification errors). This change can be made on the Properties



dialog of each SAP connection in the SAPGUI login application.
Edit the properties of each connection and click the Advanced
button.

On the Advanced Options dialog, deselect Default codepage and select your
preferred language. Click OK to accept the change.



10 Now simulate the actions of a typical user transaction. Login with
username and password. Hit Enter.

11 Expand the tree and double-click the Owner item.



12 Right-click a time frame and select Create Appointment from the context
menu to create a new appointment.



13 Define the appointment by setting Title, Appointment Type, Time, and
Priority. Then click Save.



14 Now edit the appointment you created by double-clicking it.



15 Click the Delete button (trash can icon) to delete the appointment. A
confirmation dialog appears. Click Yes to confirm deletion of the
appointment.



16 Click Exit (the yellow circular button) to exit the calendar application.

17 Click Exit again to exit SAP Workbench. On the following confirmation
dialog, confirm that you wish to exit the application.


Exploring Recorded Scripts

18 Close the SAPLogon application. This ends your simulated user
transaction.
19 Stop SilkPerformer‘s Recorder.
20 Save the recorded script file.
Note If no script has been recorded, review section “Client/Server
Requirements”.
Notice three things in the generated BDL script:
• The connection is opened with the full connection string.
• During replay new active windows are verified based on their titles.
• The login string must be customized with a parameter because the
password value wasn’t retrieved during recording.

The first step in analyzing and customizing a test script is executing a TryScript
run to look for replay errors.



Both recorded and replayed test scripts can be opened in TrueLog Explorer.
TrueLog Explorer supports the visualization of SAPGUI requests and responses
in the same way it supports the visualization of HTTP client requests and HTTP/
HTML server responses. See “Customizing SAPGUI Test Scripts” and the
TrueLog Explorer User Guide for full details regarding TrueLog Explorer.

Executing TryScripts
The default option settings for TryScript runs include live display of data
downloaded during testing and the writing of log and report files.
With TryScript runs, only a single virtual user is run and the stress test option is
enabled so that there is no think-time or delay between transactions.
Procedure To execute a TryScript run:
1 Click the Try Script button on the SilkPerformer Workflow bar. The Try
Script dialog appears. The active profile is selected in the Profile drop-
down list and the script you created is selected in the Script drop-down
list. The VUser virtual user group is selected in the Usergroup area.
2 To view rendered page transitions during a TryScript run, select the
Animated checkbox.
3 Click Run.
Note You are not running an actual load test here, only a test run to
see if your script requires debugging.

4 The TryScript run begins. The SilkPerformer Monitor window opens,
giving you detailed information about the run’s progress.



Note If you selected the Animated checkbox on the TryScript
dialog, TrueLog Explorer will open, showing you the data that is
actually downloaded during the TryScript run. Each main SAPGUI
window accessed during recording is listed as a high-level
SapGuiSetActiveWindow API node in TrueLog Explorer’s tree view.
All recorded server round-trips and user actions are listed as
subnodes of corresponding SapGuiSetActiveWindow nodes.
Animated mode for TryScripts is not really necessary as replay
includes the GUI by default—having an additional animated
TrueLog might confuse results.

Exploring TrueLogs
Once you have executed a TryScript run, you can explore the TrueLog that was
generated by the script run by right-clicking the TryScript user and selecting
Explore TrueLog from the context menu. This launches TrueLog Explorer
loaded with the TrueLog from the recent TryScript run.

a Customizing SAPGUI Test
Scripts

Introduction This chapter explains how to customize a SAPGUI load test script based on the
results of a TryScript run.
What you will learn This chapter contains the following sections:

Section Page
Overview 21
SAPGUI TrueLog Structure 22
Customizing Input Parameters 24
Customizing SAPGUI User Input Data 27
Analyzing Result Files 32
Further Steps for Load Testing 33

Overview

Once you’ve recorded a test script and identified session-specific errors through
a TryScript run, use TrueLog Explorer to customize the test script so that it can
handle session-specific strings (e.g., user IDs, password,).
Note TrueLog Explorer is a powerful test script customization tool
that offers much more functionality than is demonstrated in this
tutorial. Please see the TrueLog Explorer User Guide for details
regarding content verifications, content parsing, comparison of
record/replay TrueLogs, and much more.


2 CUSTOMIZING SAPGUI TEST SCRIPTS
SAPGUI TrueLog Structure

Once you’ve generated a load test script with SilkPerformer and executed a
TryScript run, TrueLog Explorer can help you customize the script by:
• Adding content verifications - Using the Add Verifications tool,
you can gain tremendous insight into data that’s downloaded during
load tests—enabling you to verify that the content that is to be sent
by the server is correct. Verifications remain useful after system
deployment for ongoing performance management. See the TrueLog
Explorer User Guide for details.
• Adding parsing functions - TrueLog Explorer allows you to insert
SAPGUI parsing functions visually in Source screengrab view and
on the Controls view tab. Manual code writing isn’t required—
TrueLog Explorer automatically generates parsing functions in
scripts. See the TrueLog Explorer User Guide for details.
• Parameterizing input data - With user data customization you can
make your test scripts more realistic by replacing static recorded
user input data with dynamic, parameterized user data that changes
with each transaction. Manual scripting isn’t required to create such
“data-driven” tests.
For each SAPGUI function call that changes input data, you can verify return
values, parse values, and customize input data. These operations can be
executed from both Source screengrab view (by right-clicking within a control)
and the Controls tree view.

The three windows that are displayed with SAPGUI TrueLogs are:
• Tree list (left-hand pane) - Lists all SAPGUI API calls that were
included in the test run
• Source window (upper right-hand pane) - Displays the state of the GUI
at each API node. The End Request and Start Request view tabs enable
you to view both the initial and final states of each SAPGUI server
request, to see how the server request has affected the GUI display (e.g.,
the display of a new dialog or error message).
Note TrueLog screengrabs are captured only during TryScript runs,
not load tests.



• Information window (lower right-hand pane) - Displays data regarding
the most recent test run. The view tabs in this pane that are active and
applicable to SAPGUI TrueLogs are Info, BDL, and Controls. The
Controls tab offers a convenient means of viewing and working with all
customizable controls that are included on each GUI screen.

SAPGUI TrueLog Two of the main SAPGUI function types that TrueLog Explorer relies on are:
functions
SapGuiActiveSetWindow - These are top-level API nodes that indicate the
generation of new GUI windows. All actions taken on windows are grouped
below their corresponding SapGuiActiveSetWindow functions.
SapGuiRoundTrip - These are virtual nodes; there are in fact no API calls
called SapGuiRoundTrip that are sent to the server. These nodes are used to
group all client-side actions that occur in the course of each server round-trip.
Both the before and after states of round-trips can be viewed. Multiple round-
trip nodes may be included under each SapGuiSetActiveWindow node.


Customizing Input Parameters

In the previous chapter, replay execution was halted when the replay engine
checked for “******” in the password field and an error resulted. Until the
password string is customized with a variable, the script will not replay
correctly.
Procedure To customize an input parameter:
1 Select the failed SapGuiLogon method API call in TrueLog Explorer’s
tree view.
2 Select the password field in the rendered GUI window.
3 Right-click in the field and select Customize Value from the context
menu.
Note All GUI controls on the window at the selected API node are
alternately displayed below on the Controls tree window. Fields that
are changed by the current call (and can therefore be customized) are
highlighted in orange. You can right-click values in the Controls
window to access the same customization functions that are
available above in the rendered GUI window. Most controls can be
parsed for their values. Verifications can also be defined for most
controls. All available functions are accessible via context menus.



4 The Parameter Wizard opens. The Parameter Wizard enables you to
create a new parameter for the recorded password. To keep this example
simple, a constant parameter type will be used. Select the Create new
parameter radio button and click Next.
Note See the SilkPerformer User Guide for full details regarding the
Parameter Wizard.

5 Select the Constant value radio button and click Next.



6 The data type to be used is string. Click Next.

7 Define a meaningful Name for the new parameter and enter your user
password as the string Value.

8 Now execute a new TryScript run. Your password parameter will
automatically be inserted into the replayed test script and the script
should run without error.


Customizing SAPGUI User Input Data

Under real world conditions, SAPGUI application users submit unpredictable
combinations of data into forms. One goal of effective SAPGUI application
testing is to emulate such irregular and diverse user behavior using test scripts.
You can customize the user input data that’s entered into forms during testing
with TrueLog Explorer's Parameter Wizard. The Parameter Wizard lets you
specify values to be entered into form fields—enabling your test scripts to be
more realistic by replacing recorded user input data with randomized,
parameterized user data.
Procedure To customize user input data for a form field:
1 Select the Step through TrueLog toolbar button to display the Step
through TrueLog dialog.
2 Select the Customizable calls radio button and click Find Next to step
through all form fields in the TrueLog that offer input customization.
3 When you arrive at a control field that reflects user data input that you
wish to customize, right-click in the control and select Customize Value
from the context menu.
Note For this example, select the Priority field as shown in
the figure below.



Note Controls that can be customized are outlined in orange.
Controls that have already been customized are outlined in green.
Controls that are outlined in blue can have their values parsed or
verified, but they cannot be customized.

4 With the Parameter Wizard you can modify script values in one of two
ways. You can either use an existing parameter that’s defined in the
dclparam or dclrand section of your script, or you can create a new
parameter (based on either a new constant value, a random variable, or
values in a multi-column data file). Once you create a new parameter,
that parameter is added to the existing parameters and becomes available
for further customizations.
Note This example demonstrates the process of creating a parameter
based on a new random variable. See the SilkPerformer User Guide
for complete details regarding the functionality of the Parameter
Wizard.



5 Select the Create new parameter radio button and click Next to create a
new parameter.

6 The Create New Parameter dialog appears. Select the Parameter from
Random Variable radio button and click Next.

7 The Random Variable Wizard appears with the Individual strings random
variable type selected. A brief description of the highlighted variable
type appears in the lower window.



8 Click Next.

9 The Name the variable and specify its attributes screen appears. With
SAPGUI applications, all available list-box values are pre-loaded with
weight values of 1. Enter a name for the variable in the Name field and
click Next.



10 Per usage random value generation is selected by default. Click Finish.

11 Click Finish to modify the BDL form declaration of your test script so
that it uses the random variable for the given form field in place of the
recorded value. The new random variable function appears below in
BDL view.
12 Initiate a TryScript run with the random variable function in your test
script to confirm that your script runs without error.
Note Controls that have been customized appear with green
highlighting.

Additional You may find that additional customizations are useful (e.g., randomizing
customizations username and appointment-time input parameters for load testing purposes).
Customization is possible for nodes that involve changes of text, combo boxes,
checkboxes, and radio-button controls. See the TrueLog Explorer User Guide
for full details regarding available script customizations.
Note It’s recommended that you not verify or parse values that
occur in the last nodes of round-trips. This is because functions are
scripted after selected API calls. For example, if you verify a
SAPGuiPressButton function that closes the current window, the


Analyzing Result Files

verification function will subsequently attempt to verify a control on
a window that has already been closed—and a replay error will
occur.

Analyzing Result Files
Each TryScript run generates an Overview Report (see example below).
Depending on measure settings in the active profile, measures are generated for
method calls that have the optional timer parameter defined and also force a
round-trip to the SAP server. Note that not all API calls force server round-trips.

Each server round-trip creates the following measures:
Round Trips
Before SAPGUI sends data to the server it locks the user interface. In many
cases it will not unlock the interface after data is returned by the server, but
instead sends a new request to the server. Controls use this technology to load
data they need for visualization. A count of these token switches between
SAPGUI and the server is offered with this measure.
Flushes
Counts the number of flushes in the automation queue during server
communication.
Interpretation Time [s]
The interpretation time begins after data has arrived from the server. It
comprises the parsing of the data and the distribution to the SAPGUI elements.
Response Time [s]
This is the time that is spent on network communication from the moment data
is sent to the server to the moment the server response arrives.


Further Steps for Load Testing

Note An overall counter for all round trips is shown in
SilkPerformer’s Monitor window during load tests. This counter can
also be monitored in Performance Explorer as a SilkPerformer
Controller/Agent measure.

This tutorial offers only a brief overview of the steps that you may require for
your load test scenario. Other steps that you will likely need to address are listed
below. See the SilkPerformer User Guide for details regarding these additional
steps:
• Run a baseline test
• Define your workload
• Setup your monitors
- New SAPGUI monitor for monitoring SAP servers
• Run your load tests
• Analyze load test results

a SAP eCATT Integration With
SilkPerformer

Introduction This chapter explains how to make the most of SilkPerformer’s integration with
SAP® eCATT (Extended Computer Aided Test Tool).
This chapter contains the following sections:

Section Page
Overview 35
Setting Up Integration 36
Interacting with eCATT from SilkPerformer 40
Interacting with SilkPerformer from eCATT 44
Limitations 49

Overview
SAP eCATT (Extended Computer Aided Test Tool) has been integrated with
SilkPerformer. SAP’s eCATT facility allows you to create test scripts in SAP
using the scripting language of your choice. eCATT allows you to use external
test tools (i.e., SilkPerformer) while utilizing eCATT as a repository for your test
scripts. eCATT also serves as a basic test management solution for triggering
script executions. Not only can both internal and external scripts be executed
individually, they can also be combined and executed in sequence.
eCATT offers import arguments, a mechanism for calling scripts with special
input values. Scripts can not only receive input values, scripts can also set output
values when they are executed—scripts can be executed in sequence, using
input values derived from the output values of earlier script executions.


3 SAP ECATT INTEGRATION WITH SILKPERFORMER
Setting Up Integration

Note For more information regarding eCATT, please consult SAP
documentation.

This section includes detailed instructions for each of the steps that must be
completed to make use of SilkPerformer’s eCATT integration.
Procedure To configure SilkPerformer’s eCATT integration:
1 On your SAP server, register SilkPerformer as an external tool for
eCATT.
2 On your SAP server, create a new user account.
3 On the client machine where you will be using SilkPerformer in
combination with eCATT, install both SilkPerformer and the SAPGUI
client.
4 If you access your SAP server via a SAP gateway, you must create a
registry key on the client that defines your default SAPGUI connection.
5 Within SilkPerformer system settings, configure SAP eCATT server
connection data.
6 Within SilkPerformer system settings, define a SAP eCATT directory for
extended SilkPerformer test results.
Registering SilkPerformer must be registered in the ECCUST_ET SAP table. This is done
SilkPerformer in by calling the SET_EXTERNAL_TOOL function module, which creates the
eCATT necessary entries in the ECCUST_ET table. You need to method using the
following values for the parameters:
Parameter Value
TOOL_NAME SilkPerformer
PROG_ID SAPeCATTPlugIn.BorlandSPeCATT
TOOL_DESC SilkPerformer for eCATT
TOOL_DATABASE <blank>
TOOL_RUN_DB <blank>
TOOL_NO_PWD ‘X’
TOOL_NO_DB ‘X’



You can call this method using the SE37 transaction. On the first screen, enter
the function module name SET_EXTERNAL_TOOL. Then select Test / Single
Test from the Function Module menu.
In the following window, enter the parameter values as described above and
press the Execute button (F8).
Creating a specific To take advantage of eCATT integration using external tools, a standard user
user account must be generated in your system by your system administrator. This is done by
executing the ECATT_GENERATE_ET_USER program in SE38 (once per
system).
After running the report, the following steps should be executed to activate the
newly created user role:
1 In transaction PFCG, enter role SAP_ECET, and select Change. Ignore
the subsequent warning that appears.
2 Switch to the Authorizations tab and select Change Authorization Data.
3 Place your cursor over the top node of the tree display (SAP_ECET) and

Installing the client On the machine where you plan to use SilkPerformer with the eCATT
software integration, you must first install your SAPGUI client and afterward apply the
SilkPerformer installation. Whenever eCATT initiates the integration between
SilkPerformer and eCATT, SilkPerformer installs a COM object on the agent
that is called by SAP eCATT.
Setting the registry If you are accessing your SAP system via a SAP gateway, you must create a
from behind a SAP registry key for the communication between SilkPerformer and eCATT. eCATT
gateway forwards the connection that is to be used to SilkPerformer, but it is unaware of
gateways. Therefore the connection string that is passed from eCATT cannot be
used if you are behind a gateway.
You have to create a registry key under HKLMSoftwareSilk. The key must be a
string value with the name SAPeCATTLogonID; the value must be the SAP
login ID that you use when logging in to your system (i.e., the name of your
SAP connection that you specify in SAPLOGON).
Configuring SAP Connection details for SilkPerformer's communication with SAP eCATT must
eCATT connection be specified in SilkPerformer system settings. There are two options for
connecting to SAP—you can either specify a SAPLOGONID or you can specify
AS Host, RFC Type, and SystemNr settings. With either option you must specify
client, language, username, and password details. Note that when you select a
SAPLOGONID the AS Host, RFC Type, and SystemNr fields are grayed out.



Procedure To specify SAP eCATT connection data:
1 Select the System command from SilkPerformer’s Settings menu.
2 On the System Settings - Workbench dialog, select the SAPGUI group
icon.
3 The eCATT Connection tab is selected by default. From the SAPLogon
drop box, select your SAP login ID. This box is preconfigured with all
available SAP login IDs.
4 In the AS Host edit field, enter the combined router/application-server
string (e.g., H/195.61.176.22/H/194.117.106.130/S/3297/H/cpce801).
5 In the RFC Type edit field, enter either ‘3’ (for R/3) or ‘2’ (for R/2).
6 In the System NR edit field, enter the SAP system number.
7 In the Client edit field, enter the internal client ID number from the SAP
server (i.e., the value that must be entered on the SAP login screen).
8 From the Language drop box, select your language preference. The
values ‘EN’ (English) and ‘DE’ (German) are preconfigured, though you
can specify any other language abbreviation string.
9 In the Username edit field, enter your SAP eCATT username.
10 In the Password edit field, enter your SAP eCATT password.
11 Once you have completed this dialog, click Test Connection to confirm
that you have specified accurate connection details. If your connection
attempt is unsuccessful, please confirm your settings.



12 Click the OK button once you have completed configuring SAP eCATT
connection settings.

Configuring eCATT To enable the viewing of SilkPerformer result files from within SAPGUI, you
extended results can specify a UNC path to a public file share in which extended SilkPerformer
test results can be stored and accessed by users (e.g., fileserverecattresults).
SilkPerformer will use the specified directory to store the results of
SilkPerformer test executions initiated via SAP eCATT. Users can easily access
test results by clicking a link in the SAP eCATT GUI.
Procedure To configure eCATT extended results:
1 Select the System command from SilkPerformer’s Settings menu.
2 On the System Settings – Workbench dialog, select the SAPGUI group
icon.
3 Select the eCATT Results tab.
4 Select the Use SAP extended results checkbox.
5 In the SAP extended results directory field, browse to and select the
directory that is to be used for SAP extended results.


Interacting with eCATT from SilkPerformer

6 Click OK to save your settings.

SilkPerformer can be run in eCATT Standalone mode. In this mode,
SilkPerformer can be used to:
• Upload projects to SAP eCATT
• Open projects from SAP eCATT
SilkPerformer also allows you to specify import and export arguments that can
be used to exchange values between eCATT scripts.
Uploading a project to The menu entry Upload Project into eCATT from the File / SAP eCATT menu
eCATT allows you to both upload new projects to SAP and update existing projects.
When uploading a project, the project is exported with all of its dependent files
(e.g., data files, include files) and uploaded to SAP eCATT to a BlobId and
Version that you define in the Save Project into SAP eCATT wizard.



The first step prompts you for the SAP server connection that is to be used for
uploading the project:

The second wizard step prompts you for the BlobId and Version:

In the third step you have to define the user type that is to be the primary user
type in the script. As you may have multiple user types configured in your



project, you must define the user type that is to be executed by default when
eCATT executes scripts:

Opening a project The menu entry Open Project from eCATT from the File / SAP eCATT menu
from eCATT allows you to open an existing project from SAP eCATT.
When opening a project, the project is downloaded to a temporary directory and
then imported to SilkPerformer Workbench. A downloaded project is identified
by the BlobId and Version that you define in the Open Project from SAP eCATT
wizard.
The first step in the wizard prompts you for the SAP server connection that is to
be used to download the project:



The second step prompts you for the BlobId and Version of the project that is to
be downloaded.

Now you can make changes to the project. If you want to update the project in
eCATT after you have completed your changes, simply upload the project using
the Upload Project into SAP eCATT command on the SAP eCATT menu.
Defining import/export eCATT offers import arguments, a mechanism for calling scripts with special
arguments input values. Scripts can not only receive input values, scripts can also set output
values when they are executed—scripts can be executed in sequence, using
input values derived from the output values of earlier script executions.
To define import and export arguments, SilkPerformer project attributes are
used. Project attributes that serve as input arguments must have the prefix
SAPIMPORT_. Project attributes that serve as output arguments must have the
prefix SAPEXPORT_.
Note Only project attributes of type string are accepted, since SAP
only allows string data types.


Interacting with SilkPerformer from eCATT

Following is an example that defines two input arguments and one output
argument:

In a script you access these input values as follows:
AttributeGetString("SAPIMPORT_Username", sUsername);
AttributeGetString("SAPIMPORT_Password", sPassword);
The output value is set as follows:
AttributeSetString("SAPEXPORT_SomeResult", "thats my
result");

From eCATT it’s possible to utilize SilkPerformer as an external test tool by:
• Creating a new SilkPerformer script
• Editing/Viewing an existing SilkPerformer script
• Executing a script in one of three modes:
- “Normal” without SilkPerformer Workbench
- “Debug Mode” with SilkPerformer Workbench and the option of
adjusting settings before executing the script
- “With Surface of External Tool” with SilkPerformer Workbench



Creating a new Within SAP eCATT (SECATT transaction) you can create a new SilkPerformer
SilkPerformer script script by specifying a test script name (blobID), a version, and SilkPerformer for
eCATT as the external tool, as shown below:

Now click the Create Object button (or press F5). This creates an empty
SilkPerformer script and stores it in the eCATT repository. On the following
screen you must enter all required fields before you can edit the script with
SilkPerformer. Once you have completed all required fields, click the Script
toolbar button. SilkPerformer then opens and downloads the newly created
project in Edit mode (for other available options, please see the next chapter).



Editing/viewing an Within SAP eCATT (SECATT transaction) you can both edit and view an
existing SilkPerformer existing SilkPerformer script by specifying the test script name (blobID) and the
script version, as shown below:

Now you can either click the Display Object (F7) button or the Change Object
(F6) button to view or edit the eCATT script. On the following screen you can
click the Script button to either view or edit the script in SilkPerformer.
If you are only viewing the script, SilkPerformer downloads the project from
SAP eCATT and opens it in Read-Only mode. You can go back to eCATT by
selecting Close Project without Save from the SAP eCATT menu.
If you are opening the script in Edit mode, SilkPerformer downloads the project
from SAP eCATT so that you can modify the script. Once you have completed
your modifications you have three options for returning to SAP eCATT—select
one of the following from the SAP eCATT menu:
• Save Project into SAP eCATT
The project is saved to SAP eCATT and you can continue working in
SAP eCATT.
• Save Project into SAP eCATT and Continue
The project is saved to SAP eCATT, but remains open in SilkPerformer
so that you can perform further modifications.
• Close Project without Save
The project is closed without saving your changes and you can continue
working in SAP eCATT.



Executing a Within SAP eCATT (SECATT transaction) you can execute a SilkPerformer
SilkPerformer script script by specifying a test script name (blobID) and version, as shown below:



Once you have entered these values, click the Execute button (F8) to go to the
execution dialog where you can specify start options for the script:

Depending on the Mode for Ext. Tool selection, the test will either be executed
without SilkPerformer Workbench (Normal), with SilkPerformer Workbench
(With Surface of External Tool), or in the attended debug mode with
SilkPerformer Workbench (Debug Mode).
In With Surface of External Tool mode, SilkPerformer launches and
immediately executes the primary user type. After executing, SilkPerformer
closes.
In Debug mode, SilkPerformer opens the Baseline test dialog and waits for the
user to begin the test. The user can perform some modifications to the project
before the test is actually executed. When the test is finished, the user can use
the Finish and Return Results command on the SAP eCATT menu to report back
the results of the most recently executed test run.
As with other eCATT scripts, SilkPerformer scripts can be executed from other
eCATT scripts and executed in sequence with other scripts.
To do this, create a simple eCATT script that calls an external script using the
REFEXT method. Once you have specified the blobId and version of the script


Limitations

that you want to execute, double-click the second parameter of REFEXT and
explore the external project (see the example below):

You will see the various scripts that are there-one should be marked is_main.
You will also see all import and export arguments.

Limitations
The following points should be considered when working with SilkPerformer’s
eCATT integration.
Script name length When uploading a SilkPerformer project, you must specify the primary script.
This is the user type that will be executed by default and marked as the main
script within eCATT. The name of the user type is a combination of the BDL
script name, user group, and profile (e.g., a script called test1.bdf that defines a
user group called VUser, and a profile called Profile1, results in an internal
representation of the user type as test1.bdf__VUser__Profile1).
When SAP triggers SilkPerformer to execute a script, SAP specifies the name of
the primary script as shown in the example above, (test1.bdf__VUser__
Profile1).
A bug in the current versions of SAP eCATT truncates such passed values to 32
characters. Though SAP will likely address this issue in future patches, it is quite
possible that you are running a SAP system with this limitation.


Limitations

The problem with the 32-character limitation is that during execution in normal
mode, SilkPerformer can not find the passed user type because the name has
been truncated. Therefore you will receive an error indicating that the script can
not be found.
To work around this problem, make sure that the combination of script name,
user group, and profile does not exceed 32 characters—28 characters in fact as 4
underscore characters are used to separate the values.
So save your script files with short names, use short names for user groups, and
use short names for profiles.
Default values for During testing efforts with various SAP systems, a problem with default values
arguments in eCATT arguments has been identified. With some older patch levels of SAP
eCATT, default values are not passed to SilkPerformer when running script
executions from external eCATT scripts. If you experience a problem of default
values not being passed for arguments, update your SAP eCATT patches.
Recording in edit- When recording a SAPGUI script in SilkPerformer while in the “edit” mode of
mode an eCATT script triggered from within SAP eCATT, you run into the following
problem: When you begin a new session during recording you actually have two
SAP connections open on your system—the connection that you are recording
on and the connection that is still open from eCATT. Therefore you will see two
SapGuiOpenConnection calls scripted in your script, and the
SapGuiSetActiveConnection contains a connection ID of 1. This is what you
will see in your recorded script:
gsConnID := SapGuiOpenConnection(" ecatt connection",
"SapGuiOpenConnection");
SapGuiOpenConnection(" recorded connection",
"SapGuiOpenConnection");
SapGuiSetActiveConnection("/app/con[1]");
You must remove the first SapGuiOpenConnection entry and change the
SapGuiSetActiveConnection to use the return value of the 2nd
SapGuiOpenConnection. After this modification, the script should look like
this:
gsConnID := SapGuiOpenConnection(" recorded
connection", "SapGuiOpenConnection");
SapGuiSetActiveConnection(gsConnID);
