Summary :
In SAP environments with blanket purchase orders or service purchase orders where invoice check is deactivated, incorrect handling of negative quantity values (like BPREM) can cause a DYNPRO_CONVERSION error when accessing the item list in Table Control. This issue stems from incorrect credit note versus invoice postings affecting DRSEG-BPREM entries leading to errors in routine BET_ANALYSE (LEINRF05). To resolve, quantity display fields irrelevant for these purchase orders should be hidden by modifying screen configurations (screen 0203 or 6310) to add "MNG" to modification group 4 for fields like DRSEG-BPREM, eliminating display and preventing errors. Attached corrections must be applied, and screens must be adjusted and activated following SAP guidelines.
