--------------------------------------------------------------
Hello Anoop, sum(x*y) couldn't be translated to sum(X) and sum(Y) with any
operator, so it is not supported by Kylin, unless you define a column "z" =
"x*y" in the source table, and then define "sum(z)" as a measure. If you're not
willing to add this column in your hive table, you can define it in a hive
view, and then use the view as the cube fact table.

> supported for * while executing SQL: "select
> sum(riskscoreinitial*cyc_xxx_balanceAdb), cyc_xxx_cyclesdelinquent from
> fct_profit_table_monthly group by cyc_xxx_cyclesdelinquent LIMIT 50000"

> My query looks something like this :
>
> select sum(<Metric1>*<Metric2>), <dim1> from <table> group by <dim1>
> Any guidance will help
