I have a requirement MS Project was probably not intended for, but maybe there is a tricky way to do this.
We have a lot of "resources" that are really software licenses. For example, if our license to use BigSoft 2.2 expires on 15 June, then all the projects using BigSoft 2.2 will grind to a halt the next day, 16 June. Our Contracts department does not always renew licenses on time. Similar resource behavior exists for things like server farms being turned off for good, etc.
The problem is that each one of the 70 or 80 ongoing tasks uses these resources, but the resources are never overcommitted, since they are, for all practical purposes, "Machine infinite". The only thing that kills us is when the resource literally goes bye-bye for, say, a month.
I COULD just state that each task uses, for example, 1/1,000 of the resource, but Project doesn't allow percentages that small. I COULD create a resource group with a pile of pseudo resources with similar names to avoid this, but that has the evil smell of a contrived work-around. Before I just go hog-wild into the world of workarounds, gray tape, and stitched-together solutions, I thought I would throw the problem out to the Community.
