Re: Cube connection

Hi @kishoresakamuri,


Based on my test, it's not supported to do data modeling in SSAS cube live connection, includes create a measure, calculated column or table.


To do data modeling, we can connect to SSAS cube in Import mode. In your scenario, you can write a MDX query to retrieved useful data.

Re: Cube connection



1. Live Connection.

    We can't do anything using DAX here. All the stuff u have to in SSAS cube itself.

     In live connection there is no data import on your Local so it should be fast.


2. Import mode.

     We can do all the DAX stuff here.

     All the datas are loaded in local so it might slow peformance.


My Suggestion:


Go with Live Connection, Without live connection y u went to cube ?

if u want to create new column or measure we can do in SSAS Cube itself. it was increase your performance dude.


SSAS - Power BI id best combination , when u go with Live connection

Re: Cube connection

Hi @Baskar,


Thanks for your reply. What about when you need to connect two data sources and would like to build calculations off of them? i.e. I would like to leverage a sales report and a forecast report that are from different sources. If I use a live connection I can no longer use the "Get Data" function?


In this case, is building a DAX import my only option?

Re: Cube connection

Hi @Baskar,


What would you recommend for scenarios where you want to leverage two data sources, one cube and one excel table? When you use the cube as a live connection, the Get Data function is no longer available, so you cannot build calculations, connect other data etc. In this case is using the import model and DAX your only option?


Please let me know.

Re: Cube connection

Dear Friend,


Sorry for my previous one. 
Import is always faster then live connection. It is based on the data size.

let come to here.


1. If u connect one source as live connection we can't use another connection as import.


solution for this scenario.

1. Try to import that excel file into cube and do the all modelling and calculation in cube itself. 


2. Change the live connection to import then do the calculation here.


Note :

Few updates back Power BI introduce one new feature. that we can do the DAX calculation in power bi desktop if even connected with Live source too.
