• What is the cause and solution for SAP error message GENIL_WCF122 - Object &3 - method &1: parameter struct. &2 is not defined in dictionary ?

  The SAP error message GENIL_WCF122 indicates that there is an issue with a method in the SAP Gateway framework, specifically related to a parameter structure that is not defined in the dictionary. This error typically occurs in the context of the SAP Gateway and the Component Interface (GenIL) layer when there is a mismatch or a missing definition for a parameter structure that is expected by a method.
  Cause:
  
  Missing Structure Definition: The parameter structure specified in the method is not defined in the data dictionary (DDIC). This could happen if the structure was deleted or not created properly.
  Incorrect Method Signature: The method signature in the service definition may not match the actual implementation, leading to discrepancies in expected parameters.
  Transport Issues: If the object was transported from one system to another, the structure may not have been included in the transport request.
  Development Errors: Errors during the development phase, such as typos in the structure name or incorrect references.
  
  Solution:
  
  Check Structure Definition: Verify that the structure mentioned in the error message is defined in the data dictionary. You can do this by using transaction SE11 (Data Dictionary) to search for the structure.
  Update Method Signature: If the structure is missing, you may need to create it or update the method signature to use a valid structure that exists in the dictionary.
  Transport Check: If the issue arose after a transport, ensure that all necessary objects, including the structure, were included in the transport request.
  Rebuild Service: If changes were made to the data model or method signatures, consider regenerating the service or reactivating the service definition in transaction /IWFND/MAINT_SERVICE.
  Debugging: If the issue persists, you may need to debug the service implementation to identify where the incorrect reference is being made.
