• What is the cause and solution for SAP error message CBGLBC013 - Specify a changing parameter in function module &2 ?

  The SAP error message CBGLBC013 indicates that a changing parameter is not specified in the function module you are trying to call. This error typically occurs when you are working with function modules that require certain parameters to be defined as "changing" but they are not properly specified in your call.
  Cause:
  The error arises when:
  
  A function module is called without specifying a required changing parameter.
  The function module is designed to modify the data passed to it, but the calling program does not provide the necessary parameters as changing.
  
  Solution:
  To resolve this error, you should:
  
  
  Check the Function Module Definition: Go to transaction SE37 (Function Module) and look up the function module mentioned in the error message (denoted as &2). Review the parameters and identify which ones are marked as "changing".
  
  
  Modify Your Call: Ensure that when you call the function module, you are passing the required changing parameters. For example, if the function module has a changing parameter named CHANGING_PARAM, your call should look something like this:
  CALL FUNCTION 'FUNCTION_MODULE_NAME'
    CHANGING
      CHANGING_PARAM = your_value.
  
  
  Review Documentation: If available, check the documentation for the function module to understand the expected parameters and their roles.
  
  
  Debugging: If you are unsure which parameters are required, you can set a breakpoint in the function module and debug the call to see what parameters are being passed.
  
  
  Related Information:
  
  Changing Parameters: In SAP ABAP, changing parameters are those that can be modified by the function module and are expected to return modified values to the calling program.
  Function Module Documentation: Always refer to the documentation of the function module for detailed information about its parameters and expected behavior.
  Transaction Codes: Use SE37 to view and analyze function modules, and SE80 for broader object-oriented development.
  
  By ensuring that you correctly specify all required changing parameters in your function module calls, you should be able to resolve the CBGLBC013 error.
