Is it possible to simulate a delta load on BW side?

Hello experts,

This is our situation: we have 2 ODS's A & B connected. B is the data target of ODS A and is loaded by delta loads.

I did the first init load successfully and now I want to run a delta load to check how data will look. There is a problem though, queue delta has been deleted in R3 and the PSA for ODS A as well. Is there a way to "manipulate" data in ODS A so when I run a delta, ODS B picks up the records I have modified?
