Correct measure to use to mapping in Bridge table

[InsHunter]

Hi,

Being a new bie to PBI Need help to arrive at correct measure to take in to account the bridging table .
Recreated my actual case with simple sample data.
Two fact tables,Three dim tables and a Bridge table.
Bridge table has n to 1 relationship as well as 1 to n relation ship between ID1 and ID2

My current measure does not take in to account the relation ship while calculation as it still calculates the values for independent IDs  and not taking the ID  mapping to account. Expected correct values given in red after aggregation.

Enclosing the PBIX sample file.
Deeply appreciate your support.

Thanks.

Request to confirm whether the below approach is right in current context

Energy_per_cum(Rev1) = 
CALCULATE(

VAR Units =
CALCULATE(
    [Energy (Units)],
    TREATAS(
        SUMMARIZE(
            Bridge_Table,Bridge_Table[ID1]),
            Fact_Table1[ID1])
)

VAR Flow_cum  = 
CALCULATE(
    [Flow (Ltrs)],
    TREATAS(
        SUMMARIZE(
            Bridge_Table,Bridge_Table[ID2]),
            Fact_Table2[ID2]
    )
)

VAR Units_per_Cum = DIVIDE(Units,Flow_cum)

RETURN Units_per_Cum
)

Yeah, sort of.  The good thing about TREATAS is that it works (better) without joins.

[lbendlin]

Are you familiar with the TREATAS function?
