We have a rather large old multidimensional 2012 SSAS cube, 120+ dimensions and a whole bunch of measures. It was created 5+ years ago. It is used as the source for a suite of SSRS reports and was never designed to be exposed directly to users so a
lot of the naming conventions are rubbish and there are a lot of redundant attributes.
We are now starting to use Power BI to make this available to power users. Problem is the cube would really need a good tidy
up but I cant touch it because all the reports would break and there are more than 100 of them. I know I could use a
perspective to hide some stuff but I can't use that to rename attributes etc. I don't want to create a copy and have to
maintain 2 cubes, one specifically for Power BI.
Is my best option to create an imported dataset in Power BI Desktop, edit this, publish to the service, stick on a refresh
schedule and share with everybody? I guess I then create roles on the dataset and manage permissions that way?
I'm not sure if all this would actually be better than just creating another cube!!
Any help / thoughts / advice much appreciated - thanks.
