  Check the Inbound Message: Review the inbound message to ensure that all PO items are included. Verify that each item has the required fields populated.
  Validate Mapping: If you are using middleware or an integration tool, check the mapping configuration to ensure that all necessary fields are correctly mapped from the source system to SAP.
