Here at my company, we use ePDM and Enovia V6 (also known as eMatrix) side-by side. I want to create an ePDM workflow splits our design cycle into 2 parts: the "in development" stage before we upload to Enovia, and the "Controlled" stage after. Put simply, I want to use numeric revs up to a certain point, then switch to letter revs once we hit a certain level of maturity. Once we begin using letter revs, I want to start from Rev A. Is there a way to tell ePDM to switch from number to letter revs (starting at Rev A) once it makes a certain transition? The diagram below should help clarify.
