What's the best way to disallow resources to associate transactions with CLOSED projects? 1. Inactivating - Nope. We need to see the project record. 2. Allow Time Entry = F and Allow Expenses = F - associating transactions through Checks, Vendor Bills, etc. is still possible 3. Train users not to - Difficult Am I missing something? I think it must be native.

If they are resistent to all that then you can do scripting to throw up a nag. You can also set the user preferences to see Inactive projects. The final option I have is use a Saved Search email alert to let someone know when one of these projects is added to a transaction.

About that preference, do you mean the Include Inactives in Global and Quick Search?

yes, that way they can find and see the inactive projects

Thanks but not that user-friendly. It seems that there's no native functionality for this. I might check workflow first. Thanks again!
