How to get grand total from Difference of monthly averages to provide sum not average?

[VinhTon]

Desired result: get sum of Sales by workdays (sum of monthly diff) = 129,496 instead of 196,024.74

Background: trying to get the grand total sum of monthly difference between the average of sales by workdays. Have figured out all the parts including getting grand total of averages but it does not work with month;y differences. Ruled out hasonevalue as it works fine with sum of averages.

Thanks to the community help, I am confident about getting the sum of averages from this previous post. Don't know how to troubleshoot the sum of diff of avgs though.

Details

• See pbix file
• Sales by workday (avg): 

  DIVIDE( SUM(financials[Sales]), [Num Of Workdays] )
  

• Sales by workday (sum avg): 

IF (
    HASONEVALUE ( 'Date'[Month Year] ),
    [Sales by Workdays (avg)],
    SUMX ( VALUES ( 'Date'[Month Year] ), [Sales by Workdays (avg)] )
)

• Sales by Workday (avg prev month) =

  CALCULATE( financials[Sales by Workdays (avg)], PREVIOUSMONTH( 'Date'[Date] ) )

• Sum of monthly diff =

  financials[Sales by Workdays (avg)] - financials[Sales by Workday (avg prev month)]

• Sales by Workdays (sum of monthly diff) =
  

           var x = [Sales by Workday (monthly diff)]
  
  Return
  
              IF( HASONEVALUE( 'Date'[Month Year] ), x,
  
              SUMX( VALUES( 'Date'[Month Year] ), x )
  
   )

Hi @VinhTon ,

Please simply use:

Sales by Workdays (sum of monthly diff) = SUMX(VALUES('Date'[Month Year]),[Sales by Workday (monthly diff)])

Hi @VinhTon ,

You may try :

Measure = 
var _t= SUMMARIZE(ALLSELECTED(financials),financials[Month Year],"sum",[Sales by Workday (monthly diff)])
return IF(HASONEVALUE(financials[Month Year]) ,[Sales by Workday (monthly diff)],  SUMX(_t,[sum]))

If it still not work , please share me with your pbix file after removing sensitive data. Refer to:

You could try

Sales by Workdays (sum of monthly diff) =
IF( ISINSCOPE( 'Date'[Month Year]), [Sales by Workday (monthly diff)],
SUMX( VALUES('Date'[Month Year]), [Sales by Workday (monthly diff)] )
)

Also gives 196,024
