LO Extractor with delta records after migrating 3.x data flow

Hello, We had 3.x data flow with transfer rules / update rules. And we were loading the delta records with InfoPackage in one DSO periodically. It worked fine. We are using LO Extractor (2LIS_02_ITM). Now we have migrated the 3.x data flow into 7.x data flow with Transformaiton & InfoPackage/DTP. We load the delta data with InfoPackage into PSA (we delete PSA table before we load new delta records into PSA). It works fine. It fetches only delta records from DataSource into BW. Then we load the DSO with "Data Transfer Processes (DTP)". When we take Extraction Mode "Full" in DTP, we get an error message as the ODS has delta records till now and now records come with Full. When we switch Extraction Mode to "Delta" in DTP, the delta records from PSA into DSO can not be loaded (I don't know why I get a lot more records in DSO). Any help will be appreciated. Moha
