Variable usage in CALCULATE statement

[rmsaunders]

Hello. I'm new to Power BI and DAX, and I'm trying to get the following code more compact:

This works:

calc_TY_Sales_YTD =

VAR var_Metric = SELECTEDVALUE(table_Sales_Metrics[Metric])

VAR var_TY_sales_YTD =

SWITCH(TRUE(),

var_Metric = "Units", CALCULATE(SUM(SALES_TABLE[qty_sold]), DATESBETWEEN(DATE_TABLE[date], [calc_Report_Start_Date], [calc_Report_End_Date])),

var_Metric = "Cost $", CALCULATE(SUM(SALES_TABLE[dollar_sold]), DATESBETWEEN(DATE_TABLE[date], [calc_Report_Start_Date], [calc_Report_End_Date])),

var_Metric = "Retail $", CALCULATE(SUM(SALES_TABLE[retail_sold]), DATESBETWEEN(DATE_TABLE[date], [calc_Report_Start_Date], [calc_Report_End_Date])))

I'd rather do this...

calc_TY_Sales_YTD =

VAR var_Metric = SELECTEDVALUE(table_Sales_Metrics[Metric])

VAR var_Sales_measure =

SWITCH(TRUE(),

var_Metric = "Units", SUM(SALES_TABLE[qty_sold]),

var_Metric = "Cost $", SUM(SALES_TABLE[dollar_sold]),

var_Metric = "Retail $", SUM(SALES_TABLE[retail_sold]))

VAR var_TY_sales_YTD =

CALCULATE(var_Metric, DATESBETWEEN(DATE_TABLE[date], [calc_Report_Start_Date], [calc_Report_End_Date]))

...or this...

calc_TY_Sales_YTD =

VAR var_Metric = SELECTEDVALUE(table_Sales_Metrics[Metric])

VAR var_Sales_measure =

SWITCH(TRUE(),

var_Metric = "Units", SALES_TABLE[qty_sold],

var_Metric = "Cost $", SALES_TABLE[dollar_sold],

var_Metric = "Retail $", SALES_TABLE[retail_sold])

VAR var_TY_sales_YTD =

CALCULATE(SUM(var_Metric), DATESBETWEEN(DATE_TABLE[date], [calc_Report_Start_Date], [calc_Report_End_Date]))

...but neither of thise seem to work.

Am I stuck with the first method, or am I missing something?

Thanks.

Hi @rmsaunders,

Do you have any performance issue? Or just want to compact the formula? If so, please try out this one. 

calc_TY_Sales_YTD =
VAR var_Metric =
    SELECTEDVALUE ( table_Sales_Metrics[Metric] )
VAR var_TY_sales_YTD =
    CALCULATE (
        SWITCH (
            var_Metric,
            "Units", SUM ( SALES_TABLE[qty_sold] ),
            "Cost $", SUM ( SALES_TABLE[dollar_sold] ),
            "Retail $", SUM ( SALES_TABLE[retail_sold] )
        ),
        DATESBETWEEN (
            DATE_TABLE[date],
            [calc_Report_Start_Date],
            [calc_Report_End_Date]
        )
    )
RETURN
    var_TY_sales_YTD

If it doesn't help, please provide a sample that we can download or copy with. Please mask the sensitive parts first.

Best Regards,

I just wanted to compact the formula, and your solution has done that.

Thanks!

Hmm, probably a better way, can you share sample data that can be copied and pasted so that I can try a few things? Please see this post regarding How to Get Your Question Answered Quickly: https://community.powerbi.com/t5/Community-Blog/How-to-Get-Your-Question-Answered-Quickly/ba-p/38490.
