Is it possible to restrict users from closing an open Case (I intend on creating a Open Status Reason titled 'Pending Closure') if there are records associated to that Case are in an active state?
I'd like to avoid using a plugin/code to achieve this.
Probably not without 'some' code, no. I could be wrong, but I'm not aware of anything like this.
If you were going to do it with code, you could intercept the onSave event, check for a status change, then do some queries of the related entities to check the count of 'active' related records. If any of them are > 0, interrupt the save and display an alert to the user to let them know.
