We accidentally updated one of our screw generics and created 2 new screws in a newer version of Creo than production. All users were failing when opening their assemblies. We did a work-around, but it would have been easier to just select the generic and the 2 instances and delete while using the option "Delete latest iterations of each object included in the table". However, the event manager throws up an error and says that it can't do that because the instances have only one iteration. It would be great it there was an overrideable method to tell the system to do it anyway (just as it does it an item is in someone's workspace).
