Summary :
SAP Note addresses an issue where using BAPI_PO_CREATE1 or BAPI_PO_CHANGE results in the creation of a purchase order, despite the presence of errors in the 'Return' table. This problem arises primarily when using CreateFromData1 to reference a purchase requisition linked to a non-existent WBS element within the PoAccount structure. The system erroneously creates a purchase order by transferring the account assignment from the referenced purchase requisition. The resolution requires implementing a specific correction applicable to your SAP release, with Note 456618 as a prerequisite up to Support Package SAPKH46C32.
Key words :
