Dividing from different rows into another row in Power Query

[Remi_B_Q]

Hi !

I have to add a "Mean Price" row to a table, based on a simple calculation (Turnover / Volume sold). I have turnover and Quantities sold for many stores, and for each product reference, so those have to match.

Thing is : I have 1 row for Turnover, one row for Volume, and multiple other KPIs as well. In fact, I have a "KPI" Column containing the KPI i.e. Turnover, Volume and others, and a "Value" column with the numerical value.

I'd like to keep this structure but add a "Mean Price" KPI and the calculated value on new rows, keeping the other column values such as Store, regions, SKU etc. The data file is huge already, and has a lot of other columns, here's a sample.

The data :

SKU	Supplier	Store	Période	KPI	Value
7,613E+12	Brand1	9718	P6 2023	Volume	37
7,613E+12	Brand1	9711	P6 2023	Volume	30
7,613E+12	Brand1	9389	P6 2023	Volume	59
7,613E+12	Brand1	9322	P6 2023	Volume	72
7,613E+12	Brand1	9718	P6 2023	Turnover	138
7,613E+12	Brand1	9711	P6 2023	Turnover	107
7,613E+12	Brand1	9389	P6 2023	Turnover	149
7,613E+12	Brand1	9322	P6 2023	Turnover	152

The desired outcome :

SKU	Supplier	Store	Période	KPI	Value
7,613E+12	Brand1	9718	P6 2023	Volume	37
7,613E+12	Brand1	9711	P6 2023	Volume	30
7,613E+12	Brand1	9389	P6 2023	Volume	59
7,613E+12	Brand1	9322	P6 2023	Volume	72
7,613E+12	Brand1	9718	P6 2023	Turnover	138
7,613E+12	Brand1	9711	P6 2023	Turnover	107
7,613E+12	Brand1	9389	P6 2023	Turnover	149
7,613E+12	Brand1	9322	P6 2023	Turnover	152
7,613E+12	Brand1	9718	P6 2023	MeanPrice	3,73
7,613E+12	Brand1	9711	P6 2023	MeanPrice	3,57
7,613E+12	Brand1	9389	P6 2023	MeanPrice	2,53
7,613E+12	Brand1	9322	P6 2023	MeanPrice	2,11

I need MeanPrice to be new KPI row so I favour PowerQuery instead of a DAX measure. Can you help me for the formula ? Thanks in advance !

I highly suggest utilizing DAX measures for aggregation rather than attempting to make it work in Power Query. For this example, you could do the following:

Volume = CALCULATE(SUM('Fact'[Value]), 'Fact' [KPI] IN {"Volume"})

Turnover = CALCULATE(SUM('Fact'[Value]), 'Fact' [KPI] IN {"Turnover"})

And make other explicit measures based on what is in your KPI field, then utilize those measures to create a measure for the Mean Price. 

Alternatively, you can pivot the KPI column in PowerQuery, then do SUM measures (or whatever aggregation you need) on each of the columns with their value.
