Calculating Revenue by Region

[lastnn30]

Hi

I am not familar with M or DAX. I have 3 tables in Excel (please see below).  I used PowerBI to Get these 3 tables. Went to Modeling and create relationship between these 3 tables (Power BI did it). What I want to create is a report like this:

Region	Revenu
East	?
West	?
North	?
South	?

Revenue for each product is = (1-Discount)* Unit * Price.

Now I do not know how to calculate the revenu and where? in Power Query or in Power BI?

I went to Power Query and opened FactTable and tried to Add-->Custome Column and then tried to write this formula

=(1-[Discount])*[Units]* ?????

here I stucked!! the Price is in another table (dTable1)? How can I finish that formula?

Is there an easier way I can get the revenu for this case using Power BI?  Thank you very much indeed.

 dTabel1

Product	Price
A	100
B	200

dTable2

SalesRep	Region
Alex	West

FactTable

SalesRep	Product	Discount	Unit
Alex	A	0.02	2
Mary	B	0.05	4

Thanks again for your help. I have a question please. I selected FactTable in PowerBI, and then clicked on Table Tools tab in the ribbon and then New Column, then I entered this formula in the Formual bar

Column = (1-FactTable[Discount])*FactTable[Units]*dTable1[price]

the last part "dTable1[price]" was grayed out and it seems that PBI did not recognaize that part. I checked "Model" and found that I already have 1-to-Many relationships between the FactTable and dTable1 and dTable2. Why then PBI does not recognize --> dTable1[price]

Thank you very much.

@lastnn30 , you need to use RELATED function in this case:

Column = (1-FactTable[Discount])*FactTable[Unit]*RELATED(dTabel1[Price])

Hi,

Assuming you have One-to-Many relationships between your two dimension tables and the fact table, this measure:

Revenue =
SUMX(
    FactTable,
    ( 1 - FactTable[Discount] ) * FactTable[Unit]
        * RELATED( dTable1[Price] )
)

which can then be used in a simple table visual together with the Region field from dTable2.
