• What is the cause and solution for SAP error message FKKBIX319 - Source trans. ID &1 is formally not allowed (contains lower-case letters) ?

  The SAP error message FKKBIX319 indicates that the source transaction ID you are trying to use contains lower-case letters, which is not allowed in the context of the transaction you are working with. This restriction is typically in place to maintain consistency and avoid potential issues with data processing.

  Check Configuration: If you are developing or customizing transactions, ensure that the naming conventions for transaction IDs adhere to SAP's requirements. This may involve reviewing the code or configuration settings.
  
  
  Validation: Before submitting or processing transaction IDs, implement validation checks to ensure that they conform to the required format (i.e., only upper-case letters and numbers).
  
  
  Documentation: Refer to SAP documentation or guidelines regarding naming conventions for transaction IDs to ensure compliance.
