the sum of lines containing a multiplication is incorrect.

[Laska]

Hello,

I get, I don't think so complicated problem, just not solved.

Goal: I want to calculate the total stockvalue of a warehouse.

I have the following data available:

table: article

          field: articlecode

table: stock

          field: quantity

table: purchase

          field: purchaesprice

By multiplying quantity x purchaseprice I get the stock value per item (articlecode). I get the total stock value by adding up all the lines per item.

The result I now get in the PowerBi report is as follows:

Articlecode	Quantity	Purchaseprice	Stockvalue
A123	25	125,00	3.125,00
B123	10	90,00	900,00
C123	9	275,00	2.475,00
Total	44	490,00	21.560,00
Correct			6.500,00

So it's totally wrong. The Total is also the multiplication of the totals of quantity and purchase price. It should be as mentioned by Correct.

I think it has to do with Sum and Sumx, but I'm not sure what to do.

Please advice.

Hi @Laska 

Try this:

Stock Value =
VAR _A =
    ADDCOLUMNS(
        stock,
        "Stockvalue", SUM( stock[quantity] ) * SUM( purchase[purchaesprice] )
    )
RETURN
    SUMX( _A, [Stockvalue] )

Hi 

Create 2 measures as below.

1. Stock Value1 = sum(Stock[Quantity])*sum(Stock[PurchasePrice])

2. Stock Value = sumx(SUMMARIZE(Stock,Stock[ArticleCode],Stock[Quantity],Stock[PurchasePrice]), [Stock Value1]) 

Please confirm if the solution works..!!
