• What is the cause and solution for SAP error message C$713 - Function &: Incorrect export parameter type & (pool) ?

  The SAP error message C$713 indicates that there is an issue with the export parameter type in a function module. Specifically, the error message states that the type of the export parameter does not match the expected type, which can lead to runtime errors when the function is called.
  Cause:
  
  Mismatched Data Types: The most common cause of this error is that the data type of the variable being passed to the function module does not match the expected data type defined in the function module's interface.
  Incorrect Parameter Mapping: If the parameters are not correctly mapped or if there is a mismatch in the expected structure or data type, this error can occur.
  Changes in Function Module: If the function module has been modified (e.g., changes in the parameter types) and the calling program has not been updated accordingly, this can lead to this error.
  
  Solution:
  
  Check Function Module Interface: Go to the function module in transaction SE37 or SE80 and check the interface definition. Verify the data types of the export parameters.
  Verify Calling Program: In the program that calls the function module, ensure that the variables being passed as parameters match the expected data types. This includes checking for:
  
  Correct data types (e.g., CHAR, NUMC, etc.)
  Correct structures if the parameter is a structure type.
  
  
  Adjust Data Types: If there is a mismatch, adjust the data types in the calling program to match those defined in the function module.
  Use Type Casting: If necessary, you can use type casting to convert the variable to the expected type before passing it to the function module.
  Check for Updates: If the function module has been recently updated, ensure that all dependent programs are also updated to reflect the changes.
  
  Related Information:
  
  Transaction Codes: Use SE37 to view and edit function modules, and SE80 for a broader view of the object.
  Documentation: Check the documentation for the function module to understand the expected input and output parameters.
  Debugging: If the issue persists, consider using the debugger to step through the code and identify where the mismatch occurs.
  
  By following these steps, you should be able to resolve the C$713 error and ensure that the function module is called with the correct parameter types.
