Subtract columns from 2 tables

Hello,

 

I am trying to build result table (Say C) which is derived from Table A and Table B. Table A and Table B has same columns and more than 500K records. User can filter records based on indepedent date slicer for each table.  How can I get below result in PowerBI (Table C = TableA on X date - TableB on Y date) ?

 

SELECT 

ISNULL(a.ID , b.ID) as ID,

ISNULL(a.CategoryID , b.CategoryID) as CategoryID,

ISNULL(a.Year , b.Year) as FYear,

ISNULL(a.Quarter , b.Quarter) as FQuarter,

(ISNULL(a.Val,0) -ISNULL( b.Val,0) ) as ResultVal

FROM (select * from TableA where sDate=X) as a

FULL OUTER JOIN (Select * from TableB where sDate=Y) as b

ON a.ID=b.ID and a.CategoryID=b.CategoryID and a.Year=b.Year and a.Quarter=b.Quarter
