Purchase order schedule lines can not be entered
I am tryng to enter purchase order schedule lines on a SRM 5.0 purchase order (path to page -purchase order item, item details, schedule lines). When I enter a quantity and date and hit enter the page refreshes back to blank again - thus my entered line is gone.
I have debugged and find the memory table holding my entered line (gt_sdln) is blanked out and then in function BBP_PD_PO_GETDETAILS (calls function BBP_PDSDLN_MULTI_GETDETAIL to get schedule lines details - but fails to return anything) all the details of the purchase order and items are retrieved except the schedule line.
any help appreciated.
