How to check Invalid file path
I have to write some data to a file in the application server using Open Dataset-Close Dataset.
From the selection screen I will get the file path & name. How should I check whether the file path is valid in the server? If not it is giving a short dump. So I need to check it in the event 'AT SELECTION-SCREEN' itself and give out a message like 'File path is invalid'.
But I don't know how I should check it. Please help me.
