QP:Bulk price load Concurrent program Issue

Dear Gurus,

We have a developed a custom procedure to update and insert  line items prices into existing price lists. If we have already a item is under existing price list, new price should updated to the existing line item and as well if the line item is not there it has to be inserted a new line int he exiting price list. But.But now the data is loading into interface table successfully and it is working fine up-to the interface table.

After running the QP: Bulk price load concurrent program, the data is not updating int he standard tables.
