After processing SSAS cube I get error: Server error : Process error [object doesn't exist]

Q: After processing my cubes I have this error: Server error : Process error [object doesn't exist]

A: Try to do this - go to Business Intelligence development studio, open your data source view and then on the diagram do right mouse click choose option "Refresh...". This will tell you what changes are between what you have in SSAS and what is really in database. It looks like one of your dimensions or measure groups is referencing table that does not exists in source database. By refreshing source database you will force Analysis Services check for changes and they will be reported to you. After accepting changes that Microsoft SQL Server Analysis Services reported, you will have to fix affected dimensions or measures for this problem to go away.
