• What is the cause and solution for SAP error message CATSXT124 - Interface of the smart form function module is not correct ?

  The SAP error message CATSXT124 indicates that there is an issue with the interface of a Smart Form function module. This error typically arises when the Smart Form is not correctly defined or when there is a mismatch between the expected parameters in the function module and the actual parameters being passed.
  Cause:
  
  Incorrect Function Module Definition: The Smart Form may have been modified, and the changes were not properly reflected in the associated function module.
  Parameter Mismatch: The parameters defined in the Smart Form do not match the parameters expected by the function module.
  Missing or Incorrect Import/Export Parameters: The function module may be missing required import or export parameters, or they may be incorrectly defined.
  Transport Issues: If the Smart Form was transported from one system to another, there may be inconsistencies in the transport.

  Check Smart Form Definition:
