Summary :
The BAPI_PO_CREATE1 is used for creating purchase orders but does not automatically import external item numbers unless the item number interval (ITEM_INTVL) is specified via the POHEADER-ITEM_INTVL parameter or configured in Customizing. This BAPI functionality began with Release 4.6C and applies regardless of later releases. To address the loading of item numbers, implement correction instructions provided by Note 374860. Specifically, this involves settings for POHEADERX-ITEM_INTVL in determining how item numbers are populated, either from Customizing defaults or specified intervals within the BAPI's interface, adjusting for changes detailed in subsequent Support Packages and related Notes.
