How do I tell which Edition and Version my SSAS Instance is running? In SQL Server on the database engine, you can run a SQL query like this to get the server's version info like Edition and Version, and Update Level, etc.

SELECT @@VERSION


What is the MDX equivalent for querying an SSAS (Tabular or Multidimensional) instance? Are there SSAS DMVs that can get me this answer?

I browsed the Books Online page for SSAS DMVs, but I didn't notice any DMVs that could help me. DISCOVER_INSTANCES didn't seem to have the info.

Let's assume that SQL Server Database Engine is not installed on this same server as the SSAS instance, so I cannot check this by querying the database engine.

In my case, this is for a SQL 2012 Tabular instance, but would like to know how to query Multidimensional instance too.
The easiest way is : 

using SSMS -- connect to instance --> reports -> standard reports --> General
