The answer was .."You answered your own question. You simply install another instance of SSAS."..
My MS SQL 2014 has a database engine installed with AdventureWorks DB and AdventureWorksDW DB. I also have installed Analysis server with a database containing a multi-dim cube.
I tried to install a another instance of SSAS to allow me to test the tabular mode, but the DVD disk did not give me the option to add another instance of SSAS for tabular.
What am I missing?
How do I do this .."You simply install another instance of SSAS.".. for the new instance of SSAS to source data off my already installed AdventureWorkdsDW dataBase.
Thanks - First response was the answer
