I am wanting to clean up my revenue acknowledgements by inactivating processes that are no longer used, but I don't want them to be lost forever, trying to retain historical information and retrieve/reactivate if needed. If I choose Inactivate on the revenue acknowledgement letter (first step of setting them up), it gives an error that it cannot be inactivated because an assign letters process is using it - which the process isn't running and hasn't been for a long period of time. I don't want to delete the assign letters nor the actual acknowledgement process, there is no inactivate option on these two. Any suggestions?
