How to combine 2 tables into 1

[PBI_newuser]

Hi, I want to calculate the total expense per job by month based on the below 2 tables.

For example, the total expense for WM in January is $100 and Job count in January is 2. Hence, $100/2 = $50.

For Product = Non-WM, I would like to take the total expense divide by Total Job Count for Product = WM.

Eg. In March, total expense for Non-WM is $300 and total job count for WM = 1, so the expense per job = $300/1 = $300

Same goes to Product = Non-REF, I would take the total job count for product = REF as denominator.

Table A:

Date	Product	Employee	Expense
01/01/2021	WM	ABC	100
02/25/2021	REF	BCD	200
03/24/2021	Non-WM	CDE	300
05/12/2021	Non-REF	EFG	400

Table B:

Date	Job No.	Product
01/05/2021	Job-123	WM
01/20/2021	Job-234	WM
02/12/2021	Job-345	WM
03/23/2021	Job-456	REF
05/03/2021	Job-457	REF

I'm not sure if this is what you are after, and I have had to modify your tables to showcase the measures, but here we go...

With this model:

 and these measures:

Sum Expense = SUM('Table A'[Expense])

Job Number = DISTINCTCOUNT('Table B'[Job No.])

Expense per job = 
VAR NumJobs = DISTINCTCOUNT('Table B'[Job No.])
RETURN
DIVIDE([Sum Expense], NumJobs)

Non-REF from REF =
VAR REF =
    CALCULATE (
        [Job Number],
        'Dim Product'[Product] = "REF",
        ALL ( 'Dim Product' )
    )
RETURN
    IF (
        SELECTEDVALUE ( 'Dim Product'[Product] ) = "Non-REF",
        DIVIDE ( [Sum Expense], REF )
    )

Non-WM from WM =
VAR WM =
    CALCULATE ( [Job Number], 'Dim Product'[Product] = "WM", ALL ( 'Dim Product' ) )
RETURN
    IF (
        SELECTEDVALUE ( 'Dim Product'[Product] ) = "Non-WM",
        DIVIDE ( [Sum Expense], WM )
    )

You get this...

Hi @PBI_newuser ,

Why using count of WM for Non-WM and count of REF for Non-REF?

Best Regards,
