• What is the cause and solution for SAP error message C$711 - Function &: Export parameter & does not have the correct structure ?

  The SAP error message C$711, which states "Function &: Export parameter & does not have the correct structure," typically occurs when there is a mismatch between the expected structure of an export parameter in a function module and the actual structure being passed to it. This can happen for several reasons, including:
  Causes:
  
  Mismatched Data Types: The data type of the export parameter being passed does not match the expected data type defined in the function module.
  Incorrect Structure: The structure of the export parameter does not match the expected structure. This could be due to missing fields, additional fields, or incorrect field types.
  Versioning Issues: If the function module has been changed (e.g., fields added or removed) and the calling program has not been updated accordingly, this error can occur.
  Namespace Issues: If the function module is in a different namespace and the calling program does not have access to it, this can lead to structure mismatches.
  
  Solutions:
  
  Check Function Module Definition: Go to the function module in transaction SE37 or SE80 and check the definition of the export parameters. Ensure that the structure you are passing matches the expected structure.
  Update Calling Program: If the function module has been modified, update the calling program to ensure that it is passing the correct structure and data types.
  Use Correct Data Types: Ensure that the data types of the fields in the structure you are passing match those defined in the function module.
  Debugging: Use the debugger to step through the code and inspect the values and types of the parameters being passed to the function module. This can help identify where the mismatch is occurring.
  Check for Enhancements: If the function module has been enhanced or modified by a user exit or BAdI, ensure that these changes are accounted for in your calling program.
  
  Related Information:
  
  Transaction Codes: Use SE37 to view and edit function modules, and SE80 for a broader view of the object repository.
  Documentation: Check the documentation for the function module to understand the expected input and output parameters.
  SAP Notes: Search for relevant SAP Notes that might address known issues with the specific function module you are using.
