  The SAP error message "PO145 Format & already exists" typically occurs when there is an attempt to create or modify a Purchase Order (PO) or a related document in a format that already exists in the system. This error can arise due to various reasons, including duplicate entries or conflicts in the document number or format.
  Causes:
  
  Duplicate Document Number: The system is trying to create a new document with a number or format that already exists in the database.
