How can I disable a check box in one screen?

Question

Hi,
I need to disable a check box in the screen 1106 on the program of the transaction F110. I can do that with a user exit or what I can use to do that?
Thanks!

Answer 1

you have two options :
user exit  , check if there is one for this transction
i attach program below .
field exit  :
Within the CMOD transaction type PRFB in the transaction window.
PRFB is the ok-code to bring up the field exits.
You can also use Program RSMODPRF to create field exits.
