• To start with Data Migration first
configuration should be fully completed
• Data migration is about 20% to 40% of
the total implementation expenses.

What is LSMW?What is LSMW?
• The LSM Workbench is an R/3-based tool that supports you when
transferring data from
- Non-SAP systems ("Legacy Systems") to R/3
- Once or Periodically.
• The tool supports conversion of data
• The data can be imported into the R/3 system via
- Batch Input
- Direct Input
- BAPI’s
- IDocs.

LSMWLSMW
The LSM Workbench is a tool that supports data transfer
from non-SAP systems to R/3. The main functions of the
LSM Workbench are:
- Import data (legacy data in spreadsheet tables and/or
sequential files)
- Convert data (from source format to target format)
- Import data (into the database of the R/3 application)

Principles of LSM Workbench
• Basic Principles of LSM workbench:-
– Most of the functions should reside in R/3. No collection
of individual programs on different platforms.
– The quality and consistence of the data imported into R/3
should be more important than speed and performance of
data migration.
– Existing knowledge and coding should be used.
– The developed ”mapping" and rules should be reusable
and thus be used repeatedly in projects.

Features of LSMWFeatures of LSMW
• Features:-
Integrated in R/3 and thus independent of individual platforms
The import technique to be used in an individual case, depends on the
business object as well as on the availability of standard input programs
Data consistency due to standard import techniques:
Batch input
Direct input
BAPIs (Business Application Programming Interfaces)
IDocs (Intermediate Documents)
Structured way of working, because you have to finish every step before
starting the next step

Import methods…Import methods…
Preferred methods of input are described in order of preference:
1. IDOC’s
Advantages: Fast to load, easy processing, low
programming for standard IDOC’s
Disadvantages: Good knowledge of IDOC processing
required, time consuming if changes have to be made to a
created IDOC
2. BAPI’s
Advantages: Fast to load, easy processing, logical interface
for functional/end user based on the business processes
involved.
Disadvantages: Not always complete with all input fields of a
transaction

Import Methods…Import Methods…
3. Standard/Direct Input
Advantages: Well tested method, Fast to load, easy processing.
Disadvantages: No enjoy transactions, not always complete with all
input fields of a transaction.
4. Batch Input
Advantages: Easy modifiable, all fields are available, easy re-
processing.
Disadvantages: Comparatively slow, to use new screens or tabs a
new recording has to be created, not easily usable for enjoy
transactions, dependant on user settings, difference in foreground
and background processing may occur.

Getting StartedGetting Started
Here is an example showing the way to use the conversion tool LSMW in SAP.
It starts in the start-up screen of LSMW transaction and ends with a screen on
which the results of the conversion are displayed
If you want to create or change objects, make sure that you are working in
change mode. To activate this mode, click Change in the corresponding
processing step. Only this mode provides all functions required for changing
objects

Step 1 - Enter transaction LSMWStep 1 - Enter transaction LSMW
Enter the transaction code (LSMW) or add this transaction to your favourites (right-click
with your mouse on the Favourites map in the start menu and choose Insert transaction,
type lsmw and press enter), since LSMW is an additional transaction, it is not available in
the standard SAP menu.

Step 2 – project, subproject, objectsStep 2 – project, subproject, objects
At the initial screen, you can create a new project, corresponding
subprojects and objects via Edit -> Create new entry. Alternatively you
can select from an existing project
• Project: An ID with a maximum of 10 characters to name your data
transfer project. If you want to transfer data from several legacy
systems, you may create a project e.g. for every legacy system
• Subproject: An ID with a maximum of 10 characters that is used as
further structuring attribute
• Object: An ID with a maximum of 10 characters to name the business
object

Step2 contd..Step2 contd..
- At the initial screen, ‘All Objects’ provides a list of all projects
created already.
- ‘My Objects’ displays a list of all objects you created personally
- ‘All Project Objects’ displays all objects of the selected project as
tree structure.
- ‘Project Documentation’ displays any documentation written for the
individual pop-ups and processing steps. You can print the project
documentation out, send it and save it in various file formats.
- Select ‘Documentation’ to enter your notes. After clicking, a
popup is displayed in which you can write down your personal
documentation.

By clicking the button execute or pressing the F8
key on your keyboard you go to the object, you
selected.
By clicking the button create a new object for the
selected project and subproject with the name
entered in the object field is created.
By positioning the cursor on an entry and clicking
on the button documentation, you can add change or
delete comments.

Object overview: Displays all object information for the selected object.
Information includes object information, source structures, target structures, structure
relations, source fields, target fields, field mapping.
Action log: Displays a detailed overview for all processing steps already carried out. You
can reset the action log via the menu path Extras -> Reset Action Log. This action is stored
with a reference to the user and the date.

In the step ‘Maintain Source Structures’ you define the structures of the object
with name, description and the hierarchical relationships:
Click on Change button. You can now define, change, reassign or delete
structures. All these functions are available via pushbuttons.
When you define more than one structure, a popup is displayed querying the
relations between the structures: equal/subordinate?
Note: For migration objects created via transaction recording, you may only
define one structure per recording, since only one flat target structure per
recording is available.
Maintain Source structuresMaintain Source structures

Maintain source fieldsMaintain source fields
In the step ‘Maintain Source Fields’, fields are created and maintained for the
source structure defined in the preceding step
Use source fieldnames with the same names as the target fieldnames as much as
possible, because it allows you to use the ‘auto-field mapping’ function in step 5
‘Maintain field mapping and conversion rules’.

Maintain source fieldsMaintain source fields
Different possible ways of defining and maintaining
the source fields:
Make sure that you are in change mode and the cursor is positioned on a
source structure or an existing source field
1. Create Individual source fields - By clicking on the button ‘Create source
field’ you can specify the field name, field label, field length and field type
During data read, you can specify whether date values are converted into
the internal date format (YYYYMMDD) and amount fields are converted
into the calculation format (1234.56)
‘Selection Parameter’ can be set during Read/Convert data. If you select
this indicator, the corresponding field is made available as selection
parameter when reading or converting data.
2. Maintain Source Fields in Table Form – Clicking on the ‘Table Maintenance’
button displays the fields in a tabular format.

Maintain source structure… contdMaintain source structure… contd
Different possible ways of defining and maintaining the source fields:
• 3. Copy Source Fields from Other Sources : By selecting ‘Copy Source Fields’ displays
the following options:
- Upload (Text separated with Tabs) – The source field description is stored in a text file
the columns of which are separated by tabs
- Copy from Another Object – Source field can be copied from source structure of
another object
- Copy from Data Repository – Source field can be copied from a structure in SAP Data
Repository
- From Data File (Field Name in 1 Line) - Source fields can be copied from a data file
which should be stored on the PC in the form of text separated by tabs and contain the
fields in the first line.

Maintain structure relationsMaintain structure relations
 In the step ‘Maintain Structure Relations’, the structural relationships between
source and target structures are defined. The possible target structures are defined
during the selection of the object type and the import technique
 To define structural relationships, position the cursor on the field target
structures. Clicking create Relationship button opens a window that displays the
existing source structures for selection
 If you want to change the relation, remove the existing relation first. In addition,
you can use Check to check the structural relationships for errors

Maintain Field mapping & conversion rulesMaintain Field mapping & conversion rules
• In the step ‘Maintain Field Mapping and Conversion Rules’, you assign source
fields to target fields and define how the field contents will be converted
• All fields of target structure, which you selected in the previous step, will be
displayed.
• For each target field the following information is displayed:
- Field description
- Assigned source fields (if any)
- Rule type (fixed value, translation etc.)
- Coding

Layout determinationLayout determination
 The layout of the ‘The layout of the ‘Maintain field mappingMaintain field mapping’ screen’ screen
can be determined. i.e. we can decide whether thecan be determined. i.e. we can decide whether the

By clicking this button, after clicking once on a target field (in blue), LSMW
displays the list of available source fields, by choosing one the standard rule ‘move’ is used
to link the 2 fields
By clicking this button, after clicking once on a target field (in blue), the source
field is deleted from the target field
By clicking this button, the display of this step can be changed. There are
possibilities to show or hide several aspects of the field mapping
By clicking this button, a syntax check is performed for the conversion program,
generated from the field mapping
These 3 buttons, which are available for every target field, display the help
function (‘I’), the possible entries (?) and the last one displays the documentation in LSMW

Maintain Fixed values, translations…Maintain Fixed values, translations…
In the step ‘Maintain Fixed Values, Translations, User-Defined
Routines’, you can process the reusable rules of a project, which are
defined at project level, so they are the same for all objects
Fixed value: Here you can specify the length, type flag for
lowercase/uppercase and value in addition to the name of the field.
Translation: Here you can enter information on the source field and
the target field. If you are creating a new translation you have to save
data first before you can change it
User Defined Routines: This routine can be re-used in other objects
of the project. The system adds in ‘ur_’ to the name that you suggest to
use for this routine. It opens up an editor wherein you can enter your
ABAP code

Process Step- Specify FileProcess Step- Specify File
In the step ‘Specify Files’, you describe all files to be used
If your legacy data is on the PC: In change mode, position the cursor on the line ‘Legacy data
On the PC (Front-end)’. Select Add entry. A popup is displayed. Specify file path, file name and
description and other properties
If your legacy data is on the R/3 server: In change mode, position the cursor on the line ‘
Legacy data On the R/3 server (application server)’. Select Add entry. A popup is displayed.
Specify file path, file name and description and other properties
File for Imported data: Here, the file name is entered with file extension ’.lsmw.read’.
File for Converted data: Here, the file name is entered with file extension ’.lsmw.conv’. This
file
will contain all your converted data after applying the conversion rules if any.

Process Step – Assign FileProcess Step – Assign File
In the step ‘Assign Files’, you can assign the file name in step 7 declared as source file to
the target structure defined in step 2 .
If you click on the Assign File button, after clicking once on a target structure (in
yellow), LSMW displays the list of available source files.
If you click on the Delete Assignment button, after clicking once on a target
structure (in yellow), the source file is deleted from the target structure.

Process step – read dataProcess step – read data
In the step ’Read Data’, the file specified in previous step is, as linked to the
target structures in . Even though you can select a range of transaction numbers,
the whole file is being read, only the amount of transactions written is
influenced. So for tests it is easier to read all data and convert only a certain
range, because in that step the program stops after finishing the range.

Process Step – Display read dataProcess Step – Display read data
In the step ‘Display Read Data’, you can display the read data, choosing to show
all read data or an interval as shown above. The data are shown as the source
structures, in case more source structures are being used in one transaction, the
hierarchy of the transaction is displayed by the use of a different colour legend.
By clicking on one of the lines, you proceed to the field level of the line, where
you can check the read data as shown below.

Process Step – Convert dataProcess Step – Convert data
In the step ‘Convert Data’, works like the step ‘read data’, but uses the conversion
program instead of the read program. You can define a range of transactions to
be converted, at the end of this range the conversion program stops running.
Note: It is recommended that when you load big amount of data in production,
load the first 10 records so that you can check and change when necessary.

Process Step - Display converted dataProcess Step - Display converted data
In the step ‘Display Converted Data’, you can display the converted data,
choosing to show all converted data or an interval as shown above. The data are
shown as the target structures, in case more target structures are being used in
one transaction, the hierarchy of the transaction is displayed by the use of a
different colour legend. By clicking on one of the lines, you proceed to the field
level of the line, where you can check the converted data as shown below.

Process StepProcess Step
After the step ‘Display Converted Data’ the exact content of the next steps may differ,
depending on the import technique that you have chosen in step 1. The steps displayed by
the program for the different import techniques are:
Standard batch input or recording:
Generate batch input session
