Need Formula of DAX Calculation for Quantity by Amount

[Anonymous]

Hello,

I have the below data:

Qty	Amount	Total
2	10	20
2	3	6
1	4	4

Total                                30 - Result Expecting in a new measure

I have Qty column in TableA and Amount column in TableB , I was creating a DAX calculation (A New Measure) in TableA where in i should be able to multiply TableA[Qty] * TableB[Amount] 

I am trying to create a DAX caluclation for this where in i will get the total of that calculation as "30" shown in the table and display the total '30' into a CARD visual in Power BI.

Solution i tried:

TableANewMeasure = Sum('TableA'[Qty]) * Sum('TableB'[Amount])

I am a newbie so was trying to solve this simple issue. Thanks in Advance for your help.

Thank You,

TSN

Hi , @Anonymous 

According to your description, you want to calculate the sum of the [Quantity] * [Amount]. Right?

Here are the steps you can refer to :

(1)This is my test data:

(2)We can click "New measure" and enter this:

*value = var _t = ADDCOLUMNS('Table B' , "Qty" , CALCULATE(SUM('Table A'[Qty])))
return
SUMX(_t ,[Amount]*[Qty])

(3)Then we can put this on the visual and we can meet your need:

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI! 

Best Regards,

Hi @Anonymous 

Please try

NewMeasure =
SUMX (
SUMMARIZE (
TableA,
TableB[MatNbr],
TableB[Amount],
"@Qty", SUM ( TableA[Qty] )
),
[Amount] * [@Qty]
)

@tamerj1  This is not working. The Calculation Qty * Amount is coming as incorrect.

Hi @Anonymous 

What is the relationship between the two tables?

@tamerj1 

TableB::    1->*      ::TableA

[One - Many Relationship]

Thanks TSN,

@Greg_Deckler , Thanks , Would you be more specific to this problem , As i am trying to calucate quantity * Amount = Total and the sum of that list of total. I saw the post as it is calculated based on the date.

As i am a newbie to this DAX , It would be much appreciated if you can provide a solution specific to my question -

Thanks,

TSN
