• What is the cause and solution for SAP error message LTR2_BASIS_CHECK620 - Parameter &1 is specified as changing. The value &2 is not necessary. ?

  The SAP error message LTR2_BASIS_CHECK620 indicates that a parameter specified in a function module or method is marked as "changing," but the value provided for that parameter is not necessary or is not being used in the context of the operation being performed. This typically occurs in ABAP programming when a developer has defined a parameter as changing, but the logic of the program does not require it to be changed.
  Cause:
  
  Parameter Definition: The parameter in question is defined as a changing parameter in the function module or method signature, but the logic does not modify its value.
  Unnecessary Value: The value being passed to the changing parameter is not needed for the operation, leading to this warning/error.
  Code Logic: The code may have been written in a way that does not utilize the changing parameter effectively.
  
  Solution:
  
  Review Parameter Usage: Check the function module or method where the error occurs. Ensure that the changing parameter is actually being modified within the function. If it is not being modified, consider changing its definition to an input parameter instead.
  Modify the Call: If the parameter is not needed, you can remove it from the call to the function module or method.
  Adjust Logic: If the parameter is necessary for other reasons (e.g., for consistency or future use), ensure that the logic within the function/module modifies the parameter as intended.
  Documentation: Review the documentation for the function module or method to understand the expected behavior of the changing parameter.
  
  Related Information:
  
  Changing Parameters: In ABAP, changing parameters are used to pass data to a function module or method that can be modified within that function. If a parameter is not modified, it may lead to confusion and unnecessary complexity.
  Function Module/Method Signature: Always check the signature of the function module or method to understand the expected input and output parameters.
  Debugging: Use the ABAP debugger to step through the code and observe how the parameters are being used. This can help identify why the parameter is not being modified as expected.
  
  By addressing the above points, you should be able to resolve the LTR2_BASIS_CHECK620 error and ensure that your ABAP code functions as intended.
