Summary
Before loading the data to InfoCube, sometimes we need to delete the particular date range data in InfoCube

Scope:
This article tells you how to use the Selective Deletion in Process Chains. I.e. Using “DELETE_FACTS”
TCode , how to generate the selective deletion program and then using that program how to delete the data
in InfoCube.
Why?
Sometimes, before loading the data to InfoCube, we need to delete the data based on some selective
deletion, E.g. Date, then we need to load the data to InfoCube. Every time we don’t want to do this activity
manually, and we need to automate this process.
Steps:
InfoCube Data deletion by using Selective Deletion through Process Chains. In some cases we need to
delete the InfoCube data based on selective deletion.
E.g.: We have Planning InfoCube in BW system and the data will get from APO system, in APO they will run
planning on weekly basis and they plan from SY-DATUM to next 30 days. So once APO system will
completes the SNP Weekly runs, then BW system need to extract the data from APO.
But before loading the data to BW Plan InfoCube, first we need to delete the existing data from SY-DATUM
to next 30 days data, after that I need to load the data. Because APO SNP runs will happen every Week, if
we load the data directly to Plan InfoCube, it will give wrong information in reports, because every time we
are loading from SY-DATUM to next 30 days. (E.g.: Suppose APO SNP first run date is 01.02.2009, so after
the APO run we loaded Plan data to BW InfoCube i.e. from date = SY-DATUM (01.02.2009) and to date =
01.03.3009.
Then on 08.02.2009 second SNP run was happen, so if I load data from SY-DATUM (08.02.2009) to
08.03.2009, then the data is duplicated in InfoCube, because we already loaded from 01.02.2009 to
01.03..2009 in the first SNP run, and now we are again loading from 08.02.2009 to 08.03.2009, so finally
InfoCube is having the data from 08.02.2009 to 01.03.2009 from first SNP run and 08.02.2009 to 08.03.2009
from second run, this is wrong data. So first we need to delete the data from 08.02.2009 to 01.03.2009 and
then load the data from 08.02.2009 to 08.03.2009).
We can achieve this by using “DELETE_FACTS” Transaction code. I want to automate the complete
process using Process Chains.
Give DELETE_FACTS Tcode in Command field screen and enter and give InfoCube name and select
Generate selection program option and then execute.
It will generate the following G* Program,

Take this program (GP4CZFNBBW1W0RMMVJ0908CTNKK) and then go to SE38 and give program name
and click on Variants option.
Give the Varient name ZVAR_DEL and then click on create.

It will display the selection screen. Our intension is we need to delete the data based on 0Calday (Calendar
Day), so press F1 and find the screen fields for that Calendar Day.

Click on Technical name button.
In the following screen you can find the Screen Field for Calendar Day. I.e. C016-LOW.

Once you find the screen field number then close the screen. And click on the Attributes Button.
Then give Description for the Variant. And select your screen field C016.

Click on Selection Variable and select “D: Dynamic date calculation”
Then select Name of Variable like below and double click on that it will open the following screen.

I want to delete the data from Current day to next 30 days. So select Current date –xxx, current date + yyy
and double click.
And give the values like below.

Then Save
Come back to SE38 and select Variants option and Click on Display button.

So we created a selective deletion program to delete data from InfoCube, and whenever you execute this
program with using Variant ZVAR_DEL, it will delete the data from that day to next 30 days.

So create a Process Chain and keep this Program in Process Chain.
In the above Process Chain in ABAP Program node you need to give our program name and Variant like
below.
