Query Plan become slower when applying Visual level filter

Dear all Power BI Guru,


I am creating a ranking measure which can dynamically identify TopN sales by client.


My measure is working fine, however, when I apply the ranking measure in the visual level filter, it slows down all the query plan.


My question is there any way to enhance it?


Attached is my reproduced PBIX file using Contoso dataset.!AuELRdj9xWWta0xJfF6rRXOYcQ4?e=YW9UPf

(I know with Contoso dataset the variance is very minimum, but my real report has more data point and more measure in the matrix, so the difference is quite noticeable)

Below are the snapshots for the illustration.


Snapshot 1: I apply the Ranking measure in visual level filter



Snapshot 2: I run the Performance Analyzer to get query plan



Snapshot 3: I try to analyze the Server Timings with/without "__valueFilterDM3", which is the query reflecting ranking measure in visual level filter



Snapshot 4: Server Timings without visual level filter 



Snapshot 5: Server Timings with visual level filter, which is slower than without the filter

Hi @tomtang ,


From my test, replacing [Sales Amount] with [SalesAmount] field in the original table could slightly reduce the query time.


In addition, you could try to use OPTIMIZEDAX() function



Hope these help.

Thanks @v-eqin-msft for answering!

I will try it out later with your approach.


p.s. I do hope the OPTIMIZEDAX is real.😅

Sorry if this is a stupid question, but could you just use a Top N visual level filter without a separate measure?

Hi Gabriel,


In order to make it dynamic, I have to use this approach.


Thanks for response!
