Measure Performance Issue
Please see below measure, i am trying to calculate number of customers with 80% sales. I am getting correct result but measure responding very slow almost takes 40 seconds to refresh 3 month data. I am using calculated customer table as i dont have the separate customer table in model.
Customer 80% =
VAR totalsales = [Sales]
VAR vtable =
SUMMARIZE(
Customer,
Customer[CustomerN],
"vRanking",RANKX(ALLSELECTED(Customer),[Sales],,DESC),
"vSales",[Sales])
VAR vtable2 = ADDCOLUMNS(vtable,
"v2CumSales",SUMX(FILTER(vtable,EARLIER([vRanking])>=[vRanking]),[vSales]))
RETURN
Countx(
FILTER(vtable2,[v2CumSales]<=totalsales*0.80),
[vSales]
)
