• What is the cause and solution for SAP error message C0320 - - Charact.& &: Function module & contains unpermitted exceptions ?

  The SAP error message C0320 indicates that a function module contains unpermitted exceptions. This typically occurs during the development or modification of function modules in ABAP (Advanced Business Application Programming) when the function module is defined to raise exceptions that are not allowed according to the SAP standards or guidelines.
  Cause:
  
  Unpermitted Exceptions: The function module is trying to raise exceptions that are not defined in the interface or are not allowed by the SAP system.
  Incorrect Exception Handling: The function module may have been designed to handle exceptions in a way that does not comply with the SAP standards.
  Inconsistent Exception Definitions: The exceptions defined in the function module do not match the expected exceptions in the calling programs or other related function modules.
  
  Solution:
  
  Review Exception Definitions: Check the exceptions defined in the function module. Ensure that all exceptions are properly defined and are permitted according to SAP guidelines.
  Modify Exception Handling: If there are unpermitted exceptions, either remove them or replace them with permitted ones. You can do this by:
  
  Going to the function module in transaction SE37.
  Checking the "Exceptions" tab and ensuring that only valid exceptions are listed.
  
  
  Use Standard Exceptions: Where possible, use standard exceptions provided by SAP instead of creating custom exceptions.
  Check Calling Programs: Ensure that any programs or function modules calling this function module are prepared to handle the exceptions that are defined.
  Transport Requests: If the function module is part of a transport request, ensure that the transport is correctly configured and that all dependencies are included.
