  Check Parameter Definitions: Review the definitions of the import and export parameters in the function module or method. Ensure that they are of the same data type.
  Adjust Calling Code: If you are calling a function module, ensure that the parameters you are passing match the expected types. You may need to convert data types accordingly.
  Use Data Type Conversion: If necessary, use appropriate conversion functions (like CONCATENATE, CONVERT_TO_STRING, etc.) to ensure that the data types match before passing them to the function module.
  Review Documentation: Check the documentation for the function module to understand the expected parameter types and any changes that may have been made.
  Debugging: If the issue persists, consider debugging the program to trace the values and types of the parameters being passed to identify where the mismatch occurs.
  
  Related Information:
  
  Function Module Documentation: Always refer to the SAP documentation for the specific function module to understand its parameters and expected data types.
