this is a customer function, so you need to code for this exception for the scenarios where you dont want the Changes.

Hi,

CALL customer-function '014', is called from a standard program. There might be a case where depending on certain conditions you want to restrict the user from making changes on the screen. In that case you you will raise the exeption in the implementation of the user exit where you write your own code.

In this case

RAISE no_changes_allowed. 

For further details on how to raise the exception, refer to the keyword 'RAISE'
