• What is the cause and solution for SAP error message CNV_PE798 - Importing parameter &1 of TRule &2 is not defined for TRFM parameter &3 ?

  The SAP error message CNV_PE798 typically occurs during the execution of a transformation rule (TRule) in the context of data migration or data transformation processes, particularly when using the SAP Data Migration Cockpit or similar tools. This error indicates that there is an issue with the parameters being passed to a transformation rule.
  Cause:
  The error message "Importing parameter &1 of TRule &2 is not defined for TRFM parameter &3" suggests that:
  
  Parameter Mismatch: The importing parameter specified in the transformation rule is not defined or does not match the expected parameters for the transformation function (TRFM) being used.
  Configuration Issues: There may be a misconfiguration in the transformation rules or the mapping of parameters.
  Missing Definitions: The transformation rule may not have been properly defined or activated, leading to missing parameters.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Transformation Rule Definition:
  
  Go to the transaction code where the transformation rules are defined (e.g., LTMC for the Data Migration Cockpit).
  Verify that the transformation rule (TRule) &2 is correctly defined and that all required importing parameters are specified.
  
  
  
  Review Parameter Mapping:
  
  Ensure that the parameters being passed to the transformation rule match the expected parameters defined in the TRFM parameter &3.
  Check if there are any typos or discrepancies in the parameter names.
  
  
  
  Update or Correct the TRule:
  
  If the importing parameter &1 is indeed missing, you may need to add it to the transformation rule.
  If the TRule is outdated or incorrectly configured, consider updating it to align with the current data model.
  
  
  
  Test the Transformation:
  
  After making the necessary changes, test the transformation again to see if the error persists.
