Hi Ankur thanks for your reply.
I am confused here . only those wbs are selected for archival for which lovem i.e delete flag is set. this flag is in PRPS and Proj table.
Business takes that task i.e which all WBS should be marked for deletion i.e. DLFL.
What is the role of Pre processing here??? is this like we are marking wbs codes should be deleted ?? giving no importance to what business has decided ?
Regarding your pt 2 : Data is not getting deleted from Proj and PRPS tables only. Is this default system behaviour
