Block a checkbox whit BPM

Good Morning, i need help to create a BPM code that blocks a checkbox when it has already been selected.

BPMs cannot change the User Interface to block a field. They CAN keep user from saving a change… for example, you can specify in the BPM that if a checkbox changes from True to False, throw an error… but that will not be seen until after the user presses save.

What I am looking for is that once the Received field of the entry has been checked, and saved, the user cannot check it again.

A RowRule can help here, Condtion => Recieved = true Action: Disable Received.

You are a genious.
But how do I do that?

Customization Guide is available in EpicWeb (or the Epicor Help Menu) covers RowRules pretty thoroughly. I’d start there, come back if you run into issues and we’ll gladly assist.
