first let me say i know practically nothing about SSAS.
We have a dev team who have been building a cube, it was working fine, till recently when it starting failing and not letting you go into the settings of it giving thte above error. They restored it from a backup and it started working again, only for a few days before it happened again.
This has happened 3 times now. Any ideas whats going on. I found a few blogs etc about how to resolve the issue (re-process the structure, then processfull.) Is it strange that its just started happening?
