I have to raise an error message when no value is entered to the 'description' field in the transaction codes WAK1 and WAK2. I can do this using badi or implicit enhancement. But after the error, upon pressing enter, i need to have the field editable again to re-enter. This is not happening.
I have tried giving W message and display like E. But in this case values gets saved thereafter even if the second time the field is empty. Is there a way to display error and get it editable after that without having to use access key?
