Dear..
I want to make user exit field mandatory in transaction MD01. In my case two departments wants to run it online.. but in case user is not giving any input in user exit key.. then it is taking all the materials at the plant level. this is creating problem. If the user exit field is blank..then the logic is not going into the user exit Z program. Hence I want to make the user exit key field as mandatory. So please let me know... how can I do it?
Regards,
Surya.
