Share your thoughts on DirectQuery for Power BI datasets and Azure Analysis Services (preview)

Hello. I have a use case for needing more than 3 chain lengths for direct query to AS. Our Operations department uses multiple applications in their day to day activities. We have a data warehouse where we have slowly connected most of these applications and modeled their data according to our processes for easy reporting. We still have some applications not yet added to our data warehouse and some data sources which will never be added to our DWH so we have utilized data flows to access these data sources. We have created about 4 certified datasets for the data from these applications connected to our DWH and shared these within our organization for employess to use if they desire. Now our Operations department wants a set of KPIs in a single report based on data from all of the various applications they use. Up to now, we have had to develop a single BIG dataset containing the same tables from all of the certified dataset plus the data from the above mentioned data flows. This is so we could create the single report with multiple bookmarks, buttons, and slicers. This BIG dataset has been a nightmare to maintain (over 100 measures, over 60 tables) and we would much rather compartmentalize the data into these smaller certified dataset which would be easier to maintain and manage changes. I attempted to create the same BIG model using the new DQ for AS feature but since it contained 4 datasets and about 15 dataflow tables, it would not publish to the service. Please tessahurr increase the maximum number of chains!
