  WXPO002 Unknown merchandise category &1
  
  Cause:
  This error occurs when the system encounters a merchandise category code in a purchasing document (such as a purchase order) that is not defined or recognized in the system. The placeholder &1 will be replaced by the actual merchandise category code that caused the error.

If a merchandise category is missing or incorrectly maintained in the system, SAP cannot process the document correctly, leading to this error.

  Check Merchandise Category Master Data:
  
  Go to the transaction where merchandise categories are maintained (e.g., SPRO ? Retail ? Master Data ? Merchandise Category).
  Verify if the merchandise category code shown in the error message exists.
  If it does not exist, create the missing merchandise category with the appropriate attributes.

  Ensure that the master data is consistent across systems.
  
  
  
  Transport and Authorization:
