• What is the cause and solution for SAP error message C$714 - Function &: No changing parameter & ?

  The SAP error message C$714 ("Function &: No changing parameter &") typically occurs when a function module or method is called with a parameter that is expected to be a changing parameter, but it is not defined as such in the function module's interface. This can lead to issues when the function is executed, as it expects to modify the value of the parameter but cannot do so.
  Cause:
  
  Incorrect Parameter Definition: The function module or method is defined with a parameter that is not marked as a changing parameter, but the calling program is trying to pass it as such.
  Calling Convention: The calling program may be incorrectly passing a parameter that is not intended to be changed, or it may be passing a constant instead of a variable.
  Mismatch in Function Signature: There may be a mismatch between the expected parameters in the function module and the parameters being passed from the calling program.
  
  Solution:
  
  Check Function Module Definition: Review the definition of the function module or method to ensure that the parameters are correctly defined. Specifically, check that the parameters intended to be changed are marked as "Changing" in the function module interface.
  Review Calling Code: Inspect the code that calls the function module. Ensure that the parameters being passed are variables that can be modified and that they match the expected types and definitions.
  Modify Parameter Passing: If a parameter is not supposed to be changed, ensure that it is passed as an "Importing" parameter instead of a "Changing" parameter.
  Debugging: Use debugging tools in SAP to step through the code and identify where the mismatch occurs. This can help pinpoint the exact location and reason for the error.
  
  Related Information:
  
  Function Module Documentation: Always refer to the documentation of the function module to understand the expected parameters and their intended use.
  SAP Notes: Check SAP Notes for any known issues or updates related to the specific function module you are using.
