Weighted average Measure

[Anonymous]

Hi guys,

i need to create a weighted average measure for the following scenario:

I have 3 SKU on stock with a stock reach of 10 days each (Col: Stock reach per Qty). 

They all have 5 quantities on stock (Col: Average Qty on stock).

But they have different volume (Col: Volume per stock unit). 

Now i want to weight the total stock reach of the quantities with the volume. To illustrate i created the two Helping Columns where i calculate what i need for the weighted average. The result is the Col: Total Days Stock reach weighted. This column i want to create with a measure. But without the helping columns since i dont want to create them in the Power BI Model. Here the example:

					Helping Columns
SKU	Stock reach per Qty	Average Qty on Stock	Volume per Stock Unit		Total Days Stock reach	Total Volume for stock reach	Total Days Stock reach weighted	Calculation
123	10	5	1		50	50	0,45	=50*50/5550
1234	10	5	10		50	500	4,50	=50*500/5550
12345	10	5	100		50	5000	45,05	=50*5000/5550
TOTAL						5550

How must i create the measure for this column?

Thanks guys!

@Anonymous ,

So 'Total Days Stock reach' and 'Total volumn for stock reach' are two calculate columns, right? Could you also share the dax expression of the two calculate columns?

@Anonymous ,Try like

divide(sumx(all(Table),Table[Stock Unit]*Table[Stock reach]*Table[Stock reach]) ,sumx(all(Table),Table[Stock Unit]*Table[Stock reach]))
