How have you handled releases in Solution Manager - The only way we can see to handle them is by creating a new implamentation project for the global template for every release?
Sorry it took me so long to reply - I have also been given ownership of MDM (what fun). We use implamentation templates for each project release (a new implamentation template for each release). These are all connected to one Global Template through the Solution Directory which gives a current state of what we have implamented in SAP in one place vs. searching and combining the other projects. There is no maintenace on the Global Template after the initial set up, so it fit our need.
