Request for Reverse Posting

Question

Hi,
Request for Reverse Posting - can anyone explain me this in detail with example.
Regards,RAMU.

Answer 1

Hi Ramu,
In an Infocube we can delete data in three ways,
1) Entire Data deletion
2) Selective data deletion
3) Deletion based on request ID.
After compression of Infocube, request ids become zero and data gets aggregated and moves from F fact table to E fact table, so we can delete data only in two ways
1) Entire Data deletion
2) Selective data deletion.
But if it is required  to delete data in Infocube after compression based on Request Id, we can go for Reverse Posting. We can reverse post the data only when we process the data through PSA.
If u  reverse post the data for a compressed request, the data for the compressed request is taken from PSA multiplying with
-1 for the key figure values and loaded into the data target. Now the data in the data target  is available in F table with negative key figure values. By Compression of Info Cube, data moves from F table to E table and nullifies the data in Infocube for the request ID.
Note: Since records with zero key fig values are of no use, to delete these records while compression check mark  zero elimination option in collapse tab.
Hope It helps u
Cheers....
