I am using Import Standard Purchase Orders program to import the PO's in STANDARD. I am populating the columns FROM_PO_HEADER_ID and FROM_PO_LINE_ID in PO_LINES_INTERFACE table to get the Document Ref in PO_LINES_ALL. But the program is processing the PO and populating the Document Reference fields. Am I missing anything? Please let me know. Our version is RUP6.
