How to grey out the "state" field at RITM level once a RITM(record) is completed?

[Harshil5]

How can i grey out(readonly) the "state" field at RITM(requested items) level once a RITM(requested Item) record is completed. so that once it is completed, not one can change the "state" of the RITM.

in this picture, just like "stage" is greyed out, i need to grey out "state" feild once the RITM is completed.

You can write a UI policy for state is one of closed complete, closed skipped , rejected etc make it readonly.

Alternatively you can have a ACL on that field to be readonly when state is one of closed complete, closed skipped , rejected

Hey Sonali, Thanks for your reply.

I've been trying apply your solution and im probably doing something wrong.

Would you please share the steps of applying the solution and a screen shot of either the UI policy for state, or the alternative ACL solution.

Create a UI policy on Req Item table for Active = false.

Ui policy actions - State - readonly True.
