• What is the cause and solution for SAP error message SY116 - Incorrect parameter count during PERFORM ?

  The SAP error message SY116 ("Incorrect parameter count during PERFORM") typically occurs when there is a mismatch between the number of parameters expected by a subroutine (PERFORM) and the number of parameters actually passed to it. This can happen in ABAP programs when calling a subroutine with the wrong number of arguments.
  Cause:
  
  Mismatch in Parameter Count: The subroutine is defined to accept a certain number of parameters, but the call to the subroutine provides either too many or too few parameters.
  Incorrect Definition: The subroutine may have been defined incorrectly, or the calling code may have been modified without updating the subroutine call.
  Optional Parameters: If optional parameters are not handled correctly, it can lead to this error.
  
  Solution:
  
  
  Check Subroutine Definition: Review the definition of the subroutine (using the FORM statement) to see how many parameters it expects.
  FORM my_subroutine USING param1 TYPE string
                         param2 TYPE i.
  
  
  Check Subroutine Call: Look at the PERFORM statement where the subroutine is called and ensure that the number of parameters matches the definition.
  PERFORM my_subroutine USING value1 value2.
  
  
  Adjust Parameters: If there is a mismatch, adjust either the subroutine definition or the call to ensure they match. If the subroutine is supposed to take optional parameters, ensure that the calling code accounts for that.
  
  
  Debugging: If you are unsure where the mismatch is occurring, you can use the ABAP debugger to step through the code and inspect the parameters being passed.
  
  
  Documentation: Ensure that any changes to the subroutine or its parameters are well documented, so that future modifications do not lead to similar issues.
  
  
  Related Information:
  
  ABAP Documentation: Refer to the official SAP documentation for more details on subroutine definitions and parameter passing.
  Error Handling: Implement error handling in your ABAP code to catch such issues early during development.
  Code Review: Regular code reviews can help catch these types of errors before they make it to production.
  
  By following these steps, you should be able to resolve the SY116 error and ensure that your ABAP code runs smoothly.
