Issue with loading of Delta data

Question

Hi all,
I have constructed a generic datasource using the tables ESLH,ESLL,ESKL tables with delta field as AEDAT(Changed on) from ESKL table.Created a Infocube and DSO basing on the datasource and loading is completed.Delta loads are running daily.
Now my question is how to delete the data from the infocube in the BW system if the fields ESLL-DEL(deletion indicator) and ESLL-STOKZ(reversal document) is set to active in the ESLL table in the R/3 system when the delta loading of data is completed.
can anyone have an idea of how to resolve this issue.
Thanks in Advance,
Vinay Kumar

There are a couple of ways to do this, but I would question your logic as to why you need to delete them first:
For records that are marked as "deleted" you should just filter these records in the Query designer. Doing it this way is non-destructive, and later if your business needs to know some KPI based around number of deleted records - then you will be able to answer this. If you permanently remove the data, then you cannot answer this KPI.
For records marked "reversal" you should never remove these because they affect your key figures. A reversal can also be a partial reversal and so your KPIs will be wrong if you don't include them, and in any case in reporting you never see the reversal because almost all KFs are aggregated. The only time you will see a reversal record is when you include the characteristic that identifies it as a reversal, and in most reports that is unnecessary.
Right - so now to your solution(s) - although I repeat I advise not doing any of these.
As these are custom data sources, make sure that in your source system you create abap code to fill in thr RECORDMODE for each record.
This way when you load your data to the DSO, the activation step will take care of processing deletions and reversals.
Next compress your cube and use selective deletion on the cube to remove the deleted and reversal records.
Alternatively:
Compress your cube and use selective deletion on the cube to remove the deleted and reversal records.
Then in your transformation to the cube, create a start routine which removes the records from the source package. ie the records are never allowed to go to the cube.
I hope that helps.
