DAX expression I cannot get to work - please help.
Hi.
My first post.
So I have a matrix and on this matrix I am trying to calculate in DAX a field called % of Premium.
Please see pic above, for 2017 the % of Premium value for the Liability section should be 22.14% (175607198 / 793274434)
However given the following DAX formula I get 33.61% (175607198 / 52638561)
% of Premium = SUM('Agency Scorecard 3'[Earned Premium]) / CALCULATE(SUM('Agency Scorecard 3'[Earned Premium]), ALLSELECTED())
You may be asking why I'm not using SQL to do this and the fact is that running this calculation over SQL will get me spurious results. I really need to use the row total Power BI is using.
Please help.
Here's what worked but I don't understand why!
I just added the red part and all worked.
% of Premium = DIVIDE(SUM('Agency Scorecard 3'[Earned Premium]), CALCULATE(SUM('Agency Scorecard 3'[Earned Premium]), ALLEXCEPT('Agency Scorecard 3','Agency Scorecard 3'[Loss Year]),'Agency Scorecard 3'[Summary Line ID],'Business Division'[BusinessDivisionID], VALUES('Business Division'[BusinessDivisionID])), 0)
Thanks all for your help in getting me on the right track.
Here's the post that explains why the Values function works so now I know.

You keep adding for all your report (might work with page/visualisation filters I don;t know) filters as follows:
% of Premium = DIVIDE(SUM('Agency Scorecard 3'[Earned Premium]), CALCULATE( SUM('Agency Scorecard 3'[Earned Premium]), ALLEXCEPT('Agency Scorecard 3','Agency Scorecard 3'[Loss Year]),'Agency Scorecard 3'[Summary Line ID],'Business Division'[BusinessDivisionID], VALUES('Business Division'[BusinessDivisionID]), VALUES('Agent'[Agent Alternate 1]), VALUES('Agent'[Agent Alternate 2]), VALUES('Sub Producer'[Alt Sub Producer 2]), VALUES('Managing Unit'[Managing Unit Name]), VALUES(Office[Office]), VALUES('Product Line'[Product Line Name]), VALUES(Underwriter[Underwriter Name]) ),0)

Hi. Thanks but that gave 7.28% for the example I gave. I donlt even know how 7.28% is caculated.
Hi Sureshot
Actually ALLSELECTED works on Totals. It does not impact Row and Column filters
Could you share your file via googledrive or onedrive?
