• What is the cause and solution for SAP error message RSTRAN023 - Only &1 Source Fields Are Permitted for This Rule Cateogry ?

  The SAP error message RSTRAN023 indicates that there is an issue with the number of source fields being used in a transformation rule within the SAP BW (Business Warehouse) environment. Specifically, the error states that only a certain number of source fields are permitted for the specified rule category.

  Review Rule Category:
  
  Verify the rule category being used and check the documentation or configuration settings to understand the limitations on the number of source fields allowed.
