• What is the cause and solution for SAP error message RTST_CMP_MSG021 - Import parameter missing ?

  The SAP error message RTST_CMP_MSG021 indicates that there is a missing import parameter in a function module or method call. This typically occurs when a program or function is expecting certain parameters to be passed to it, but one or more of those parameters are not provided.
  Cause:
  
  Missing Parameter: The most common cause is that the calling program or function did not provide all the required import parameters when invoking the function module or method.
  Incorrect Signature: The function module or method signature may have changed, and the calling program has not been updated to reflect these changes.
  Typographical Errors: There may be a typo in the parameter name or the way it is being passed.

  Check Function Module/Method Signature: Review the definition of the function module or method to confirm which import parameters are required. You can do this in the SAP GUI by navigating to the function module or method in transaction SE37 (for function modules) or SE80 (for classes and methods).

  Review Documentation: If available, check the documentation for the function module or method to understand the expected parameters and their data types.
  
  
  Error Handling: Implement error handling in the calling program to catch such issues early and provide meaningful error messages.
