Multidimensional or Tabular model?

$

Hi,

 

I hope some of you can give me some advise on the following:

We are currently building our datawarehouse to use with Power BI specifically.

 

As we would like to keep the data on premise, we made sure we have all the required pre-requisites.

(MS SQL 2014 BI edition, Enterprise Gateway, etc)

As a test, we created a Cube with a couple of dimensions and measures in a multidimensional model, and hooked it to Power BI.

Seems to work fine, however: there seem to be some limitations. I have spend the last year learning DAX, working with both Excel en Power BI, but it seems if I 'live' connect Power BI to our Cube, I am unable to add Measures, Calculated Collumns, and such. We can create them in the Model of course, but that is all in MDX and works quite a bit different than DAX.

 

If we where to move to a Tabular model, we could add the measures and calculated columns in the model by using DAX, but are there any downsides to using tabular? What would your preference be? A list of pro's and con's of both models in regards to Power BI would be most welcome!

 

Thank you for any help you can provide! Smiley Very Happy
