• What is the cause and solution for SAP error message MW458 - Supplier &1 and distribution center &2 are identical ?

  The SAP error message MW458 indicates that there is an issue with the configuration of a supplier and a distribution center in the system. Specifically, it means that the supplier and the distribution center are being treated as identical entities, which is not allowed in the system. This can occur in scenarios where the same code or identifier is being used for both the supplier and the distribution center.
  Cause:
  
  Identical Codes: The most common cause of this error is that the supplier and the distribution center have been assigned the same code or identifier in the SAP system.

  Solution:
  
  
  Check Master Data: Review the master data for both the supplier and the distribution center. Ensure that they have unique identifiers. You can do this by navigating to the relevant master data transaction (e.g., XK03 for suppliers, and possibly a transaction like OMDU for distribution centers).
  
  
  Correct Identifiers: If you find that the supplier and distribution center are indeed using the same identifier, you will need to change one of them to ensure they are unique. This may involve creating a new distribution center or supplier with a different code.
  
  
  Review Configuration: If the issue persists, review the configuration settings in the SAP system to ensure that there are no settings that would cause the system to treat these two entities as identical.
