• What is the cause and solution for SAP error message MN820 - Client & of external data differs from system client & ?

  The SAP error message MN820 indicates that there is a discrepancy between the client of the external data being processed and the client of the SAP system. This typically occurs during data import or data transfer processes, where the system expects the data to be in a specific client context, but the incoming data is associated with a different client.
  Cause:
  
  Client Mismatch: The external data being imported is associated with a different client than the one currently active in the SAP system.
  Incorrect Configuration: The configuration settings for the data import may not be set correctly, leading to a mismatch.
  Data Source Issues: The source of the external data may have been set up incorrectly, or the data may have been exported from a different client.
  
  Solution:
  
  Check Client Settings: Ensure that the client settings in the SAP system match the client from which the external data is being imported. You can do this by verifying the client number in the SAP GUI.
  Data Source Verification: Confirm that the external data source is correctly configured and that the data being imported is intended for the current client.
  Use Correct Data: If the external data is indeed from a different client, you may need to either:
  
  Import the data into the correct client.
  Adjust the data to match the current client context.
  
  
  Consult Documentation: Review the documentation for the specific transaction or process you are using to ensure that you are following the correct procedures for data import.
