Referenced query issue

Hi,

 

I'm trying to understand how is the "reference table" works.

 

Having 2 queries A, B, where B is a reference to A, and A is a query to my data source.

When refreshing A and B, I expect only 1 call to my data source (from A), but I see 3 calls.

2 calls are running in parallel at the same time and when finished I see the 3rd call being executed for the same query.

 

Can someone elaborate on that process?

 

Will it be more efficient if I wouln't "reference" to A but "duplicate"?

 

Thanks

    nadian I am not entirely 100% on how query calls are made but i would assume that if you have two queries A and B, where B is reference of A then during refresh only one call is made as B is reference of A and is going to be updated once A is updated. On other hand duplicate B of A means they both refernce data source seperately and so two calls will be made. 

     

    Perhaps MS insider like SamLester can confirm this for us on how query calls are made for reference and duplicates.
