  Cause
  
  Invalid Function Module: The function module specified in the error message may not exist, or it may have been deleted or renamed.
  Interface Changes: The function module may have been modified, and its interface (import/export parameters) does not match what is expected by the calling program.
  Transport Issues: If the function module was transported from one system to another, there may have been issues during the transport that caused the interface to become invalid.

  Check Function Module Existence: Verify that the function module exists in the system. You can do this by using transaction SE37 (Function Builder) and entering the name of the function module.
  Review Interface: Check the interface of the function module to ensure that it matches the expected parameters. Look for any changes in the import/export parameters that may have occurred.
  Re-transport Function Module: If the function module was recently transported, consider re-transporting it to ensure that it is correctly set up in the target system.
  Debugging: Use the debugger to trace the program that is calling the function module. This can help identify where the mismatch is occurring.
  Check for Dependencies: Ensure that any dependent objects (like data elements, structures, etc.) used in the function module are also valid and exist in the system.
