• What is the cause and solution for SAP error message C0651 - Export parameter & missing in function call ?

  The SAP error message C0651, which states "Export parameter & missing in function call," typically occurs when a function module is called without providing all the required export parameters. This error indicates that the function module expects certain parameters to be passed to it, but one or more of those parameters are missing in the call.
  Cause:
  
  Missing Export Parameter: The function module you are calling has defined export parameters that must be provided, and one or more of these parameters are not included in your function call.
  Incorrect Function Call: The function module might be called incorrectly, either due to a typo in the parameter name or by not following the expected structure.
  Changes in Function Module: If the function module has been modified (e.g., new parameters added) and the calling program has not been updated accordingly, this error can occur.
  
  Solution:
  
  
  Check Function Module Definition: 
  
  Go to transaction SE37 (Function Builder) and enter the name of the function module that is causing the error.
  Review the export parameters defined for the function module and ensure you understand which parameters are required.
  
  
  
  Update Function Call:
  
  In your ABAP code, ensure that you are passing all required export parameters when calling the function module.
  Example of a correct function call:
  CALL FUNCTION 'FUNCTION_MODULE_NAME'
    EXPORTING
      PARAMETER1 = value1
      PARAMETER2 = value2
      ...
    IMPORTING
      RETURN = return_value.
  
  
  
  
  Check for Optional Parameters: If there are optional parameters, ensure that you are not mistakenly omitting any that are necessary for the specific context in which you are calling the function.
  
  
  Review Documentation: If available, check the documentation for the function module to understand the expected parameters and their significance.
  
  
  Debugging: If you are unsure which parameter is missing, you can use the debugger to step through the code and see the function call in action. This can help identify which parameter is not being passed.
  
  
  Related Information:
  
  Function Module Documentation: Always refer to the documentation of the function module for detailed information about its parameters.
  SAP Notes: Check SAP Notes for any known issues or updates related to the function module you are using.
