Hello,
How can I hide the "Closed as Won" button on the Opportunity form based on a text field (accountnumber) in the Account entity? Each Opportunity can have one associated Account. If the accountnumber field is blank, I want the button to be hidden. I'm assuming I should use a Value Rule, but I don't know exactly how to do this for related entities.
If this is not possible to do, what would be the best workaround?
Thanks!
