Calculate average between double counting rows

[mathewsjoy]

Requested Year	Customer Name	Project	Processor Number	Ecap Price ($)	Ceiling Volume	WeightedEcap
2019	Beta	A1	XXX1	$770	204,000	157080000
2019	Theta	A1	XXX1	$770	200,000	154000000
2019	Alpha	B1	CCC2	$1,650	102,000	168300000
2020	Alpha2	C1	BBB2	$1,550	50	77500

I have data in the above format and there is many more rows, what iam trying to do is essentially do a weighted average.

Where i made a measure that does

Average Ecap Price ($) = SUM(Table1[WeightedEcap]) / SUM(Table1[Ceiling Volume])

And this works fine.

However, I've come to realise in the data set I have I have double counting deals/rows. E.g Rows 1 and 2 in the example table above.

Where a deal has the same Year, Project, Sku, Ecap Price $ BUT Differnt Customer Name and Ceiling volume.

Instead I want to do this fromula (Average Ecap Price ($) = SUM(Table1[WeightedEcap]) / SUM(Table1[Ceiling Volume])) on the data set. But where there is double counting deals, I want to take the average of the ceiling volume e.g. average of 204,000 and 200,000 and multiple that by the ecap $770 once, to get the WeightedEcap column value, just once for each double counting deal.

Does anyone know how I could achieve this?

Hi @mathewsjoy ,

You can create a calculated column as below to get it, please find the details in the attachment.

WeightedEcap = 
VAR _avgcvol =
    CALCULATE (
        AVERAGE ( Table1[Ceiling Volume] ),
        FILTER (
            'Table1',
            'Table1'[Requested Year] = EARLIER ( Table1[Requested Year] )
                && 'Table1'[Project] = EARLIER ( 'Table1'[Project] )
                && 'Table1'[Processor Number] = EARLIER ( 'Table1'[Processor Number] )
        )
    )
RETURN
    _avgcvol * 'Table1'[Ecap Price ($)]

If the above one is not your expected result, please provide more raw data in your table with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.
