Q: How do I clear Analysis Services (SSAS) database cache?
A: To clear a cache you should use XMLA command ClearCache. You can choose to clear cache for database, cube or measure group. Note: you should specify object IDs and not names. In many cases this might not be the same. To see ID of the object you can open database in the BIDS, then select object (database, cube or measure group) and check value for property ID.
