Delete existing overlapped request with ABAP routine

Hi,

i would like to delete overlapped request from InfoCube regularly with an ABAP routine. (i checked the "Request Selection Through Routine" check-box). As far as i know i can check successful request in RSSELDONE table, but how can i reach the current selection criteria? I'd like to compare them with RSSELDONE table content. How can i make difference between previous and current upload in RSSELDONE table?

Could you send me a sample ABAP code?

Thanks a lot

Richard
