• What is the cause and solution for SAP error message FL009 - EXIT function groups may not contain underscores (_) ?

  The SAP error message FL009 indicates that there is an issue with the naming convention of function groups in your SAP system. Specifically, the error states that "EXIT function groups may not contain underscores (_)." This typically occurs when you are trying to create or modify a function group that does not adhere to the naming conventions set by SAP.
  Cause:
  The primary cause of this error is that the name of the function group you are trying to create or modify includes an underscore (_). In SAP, certain naming conventions are enforced to maintain consistency and avoid conflicts. For EXIT function groups, the naming convention explicitly prohibits the use of underscores.
  Solution:
  To resolve this error, you should rename the function group to comply with SAP's naming conventions. Here are the steps you can take:
  
  
  Identify the Function Group: Determine which function group is causing the error. This is usually indicated in the error message or can be found in the transaction where the error occurred.
  
  
  Rename the Function Group: 
  
  Go to the transaction SE80 (Object Navigator) or SE37 (Function Builder).
  Locate the function group in question.
  Rename the function group to remove any underscores. Ensure that the new name follows the SAP naming conventions (typically, it should start with a letter and can contain letters and numbers, but no special characters like underscores).
  
  
  
  Check Dependencies: If the function group is already in use, check for any dependencies or references to it in your code. You may need to update those references to match the new name.
  
  
  Transport Changes: If you are working in a development environment, ensure that you transport the changes to the appropriate systems (e.g., quality assurance, production) after testing.
  
  
  Related Information:
  
  Naming Conventions: Familiarize yourself with SAP's naming conventions for various objects, including function groups, function modules, and other development objects. This can help prevent similar errors in the future.
