Selective deletion from DSO through process chain

Hello Experts,

I need to delete some specific data based on company code daily after load to a DSO.

I need to do it through process chain.

checked the forum before posting and I found a function module RSDRD_SEL_DELETION and a program RSDRD_DELETE_FACTS for deleting data in the cubes. The problem I am facing here is, I am not able to understand what parameters needs to be passed or how can I use a variable while executing this programs.

Is there any other way to do this ??

Please help.

Thanks,

Ipsita
