I need to take a vendor asset list and create a tracking calendar for it so the user can then be alerted when a renewal date is 30, 60, or 90 days out. The vendor list is done, and I have set up a calendar where the time interval is both End Dates. Simple so far.
I am struggling over how set up the alerts. I considered workflows which would be automatically triggered at the appropriate 30, 60, or 90 intervals, but have reached an impasse. A modified "approval" workflow and the 3-state one can't function as I'd like or else I haven't set things up right (always a possibility!). The solution has to be OOTB since I don't have SP Designer trainng or a developer in-house.
Any advice?
