Unable to update item Revision on Purchase order form for BPA and Quotation

Hi Team,

I have a requirement to update the item revision on the Blanket Purchase Agreement and Quotation Form. I am using PDOI approach and inserting required data on PO_HEADERS_INTERFACE and PO_LINES_INTERFACE table. On running the Import Price Catalog Program, it completes successfully. Process_code for PO_HEADERS_INTERFACE and PO_LINES_INTERFACE is ACCEPTED, but the Item revision is not getting changed. The same approach is working fine for updating unit price for BPA, price is getting changed and is also reflecting in the front end as well as backend.

Require your expertise. Let me know if further information is required.
