Need help in optimizing Dax query

Hi Team,

 

I need help in optimizing this query that i am writing in dax 

 

Debug Avg =
AVERAGEX(SUMMARIZE(approxtable,approxtable[Customer_ID],"s",CALCULATE(DIVIDE(SUM(approxtable[Sales]),DISTINCTCOUNT(approxtable[Customer_ID]),0),PATHCONTAINS(TRIM(SUBSTITUTE(SUBSTITUTE(VALUES(approxtable[Control_Id]), ",","|")," ","")),approxtable[Customer_ID]))),[s])

Re: Need help in optimizing Dax query

Hey, i got the solution. In the previous query, PathContains were taking too long as it has a callback during query execution.

So I did change my query to this

 

AVERAGEX(SUMMARIZE(approxtable,approxtable[Customer_ID],"S",
VAR OrderList = TRIM(SUBSTITUTE(SUBSTITUTE(VALUES(approxtable[Control_Id]),",","|")," ",""))
VAR OrderCount = PATHLENGTH ( OrderList )
VAR HandleNullCount = IF(OrderCount>0,OrderCount,1)
VAR NumberTable = GENERATESERIES ( 1, HandleNullCount, 1 )
VAR OrderTable =
GENERATE (
NumberTable,
VAR CurrentKey = [Value]
RETURN
ROW ( "Key", PATHITEM ( OrderList, CurrentKey ) )
)
VAR GetKeyColumn = SELECTCOLUMNS ( OrderTable, "Key", [Key] )
VAR FilterTable = TREATAS ( GetKeyColumn, approxtable[Customer_ID] )
RETURN
CALCULATE(SUM(approxtable[Sales]), FilterTable )),[S])

 

 

This query executes pretty fast. 

Thanks

Re: Need help in optimizing Dax query

Hi @shobhitgupta,

 

Please modify it as below:

 

Debug Avg =
AVERAGEX (
    SUMMARIZE (
        approxtable,
        approxtable[Customer_ID],
        "s", IF (
            PATHCONTAINS (
                TRIM (
                    SUBSTITUTE (
                        SUBSTITUTE ( VALUES ( approxtable[Control_Id] ), ",", "|" ),
                        " ",
                        ""
                    )
                ),
                approxtable[Customer_ID]
            )
                = TRUE,
            DIVIDE (
                SUM ( approxtable[Sales] ),
                DISTINCTCOUNT ( approxtable[Customer_ID] ),
                0
            )
        )
    ),
    [s]
)

Re: Need help in optimizing Dax query

Is it possible to improve query performance or achieve this in some other manner as this query is still running slow.
