As sad as it is, there needs to be focus on one way forward - that appears to be tabular. A migration path is needed, but having the two models is confusing and becoming unnecessary. Even if full sup...
'@tf: Another serious limitation for me is the Direct query functionality of tabular models, which is meant to be analogous to ROLAP cubes. The fact is that when you turn direct query on, we get a severe set of limitations, which in my view makes Direct Query as useful as an ashtray on a motorbike :) For example we cannot use direct query when combining multiple data sources. This means that creating a tabular model to query line of business applications is inpractical since I cannot combine it with other data-sources, such as a date dimension from another DB.
