Calculation using different tables with no relationship

[RavitPBI]

Table A: Outbound

Date_id	Org_id	OutboundUnits
1	80	500.00
2	80	600.00
3	80	700.00
1	86	100.00
2	86	200.00
3	86	300.00

Table B: Inbound

Date_id	Org_id	Vendor_id	InboundUnits
1	80	1	50.00
1	80	2	60.00
2	80	1	70.00
2	80	2	10.00
3	80	1	20.00
3	80	2	30.00
1	86	1	50.00
1	86	2	60.00
2	86	1	70.00
2	86	2	10.00
3	86	1	20.00
3	86	2	30.00

Table C: GoalUPH (Goal Units per Hour)

Date_id	Org_id	GoalUPH
1	80	20.00
2	80	20.00
3	80	20.00
1	86	25.00
2	86	25.00
3	86	25.00

My data model has the above setup of tables A, B and C (amongst many other tables). Unfortunately, there is no active/inactive relationship between these A, B, C tables (since my PowerBI desktop doesn't allow for many-to-many relationships). I am trying to achieve the following formula:

HoursNeeded = (OutboundUnits + InboundUnits) / GoalUPH --> for each combination of Date_id and Org_id.

So, for example, for Date_id = 1 and Org_id = 80, the calculation would (mathematically) go like:

HoursNeeded = (500.00 + (50.00 + 60.00)) / 20.00 = 30.5

I'd appreciate any help in creating the above calculation. Thanks!

@RavitPBI , Create two/three common dimension table date, org, and vendor. Accompany them with boards and then use it.

Refer to this video how two create one when they have one -https://www.youtube.com/watch?v=Bkf35Roman8

Hi, @RavitPBI 

It’s my pleasure to answer for you.

According to your description, I think you can create two slicers(column in table C) and a measure to calculate the desired result.

Like this:

HoursNeeded =
VAR dateid =
    SELECTEDVALUE ( GoalUPH[Date_id] )
VAR orgid =
    SELECTEDVALUE ( GoalUPH[Org_id] )
VAR sumunits =
    SUMX (
        FILTER ( ALL ( Outbound ), [Date_id] = dateid && [Org_id] = orgid ),
        [OutboundUnits]
    )
        + SUMX (
            FILTER ( ALL ( Inbound ), [Date_id] = dateid && [Org_id] = orgid ),
            [InboundUnits]
        )
RETURN
    IF (
        ISFILTERED ( GoalUPH[Date_id] ) && ISFILTERED ( GoalUPH[Org_id] ),
        DIVIDE ( sumunits, SELECTEDVALUE ( GoalUPH[GoalUPH] ) ),
        0
    )

If it doesn’t solve your problem, please feel free to ask me.

Hi @v-janeyg-msft,

Thanks for sharing the solution. While it seems this calculation would work with your recommendation, however, usage of slicer is not an option for me. This calculation should be performed behind the scenes without the use of any end-user interaction. Appreciate the help!

Hi @amitchandak,

Thanks for providing the right direction. The video gave some ideas to build upon my own solution using bridge tables. Appreciate the help a lot! 🙂
