Aggregation Tables: Summarization Type "Count" and "Count Table Rows" are inactive

[isabel_vasco]

Hello everyone! 

I'm working on the Mixed Storage mode PowerBI report where the detailed table is in the Direct Query mode and aggregation table is in the Import mode. For both tables I pull the data using SQL query. 

Detailed and Aggregated tables have UserID as a varchar data type, I count them using COUNT(DISTINCT USERID). When I try to manage aggregations, the summarization type Count is not active. 

Also I add to my SQL query COUNT(*) AS NB_ROWS for both tables, but the summarization type "Count Table Rows" is not active. 

How can I activate both summariozation types to manage aggregations?

Thank you!

Try creating a measure then i think it may be because of how power bi is handling the different mode of connectivity and interpretation

For directquery as the summarisation is disabled
