Calculate values in one fact table from another fact table

[BILearner]

Hi ,

I have following data model which has 2 fact tables 3 dimension tables and 1 bridge table to resolve many to many relationship. 

I am trying to calculate Sales Volume since the contract Start Date for each "Product ID" in Contracts Table using following formula

Sales Volume Since Contract Start Date=
CALCULATE ([Total Volume],
FILTER (
SalesFact,
SalesFact[INVOICE_DATE]
>= MIN ( Contracts[Contract Start Date] )
),
SalesFact[PRODUCT_ID]
IN VALUES ( Contracts[Product ID] ),
SalesFact[BILL_TO_CUST_ID]
IN VALUES ( Contracts[Bill To ID] )
)

I get correct results when I throw this measure in a table which provides Context for  MIN ( Contracts[Contract Start Date] ) . However, if I throw this measure in a card visual or in any other visual without a Contract Start date context I get incorrect results. 

Can somone please tell me how can I resolve this? I think I need to use somekind of iterator function to get the result I need, but I can't seem to figure it out.  

Thanks!

@BILearner , Try like. In case it joined with contract table and other tables, then what is need of in clause

sumx(summarize(Contracts, Contracts[Product ID] , "_1" ,CALCULATE ([Total Volume],
FILTER (
SalesFact,
SalesFact[INVOICE_DATE]
>= MIN ( Contracts[Contract Start Date] )
)
)) ,[_1])

Thank you for your advice @amitchandak I was able to build on your formula to come up with following forumla

Actual Volume =

SUMX (

ADDCOLUMNS (

SUMMARIZE (

Contracts,

'NewSKUBridge'[Product ID],

BillToBridge[Bill To ID]

),

"Act Vol", CALCULATE([Total Units Sgls],DATESBETWEEN('Calendar'[Date],MIN(Contracts[Contract Start Date]),MAX(Contracts[Contract End Date])))

),

[Act Vol]

)

However, with this formula the Date is always locked to contract start date and contract end date. What I want is a user should be able to make a selection on date slider/slicer to see back in time. However this solution doesn't allow that as the start and end dates are locked based on dates in Contract Table.

So, I wrote another measure as follows, but it is not working at all. 

Actual Volume 2 =

SUMX (

ADDCOLUMNS (

SUMMARIZE (

Contracts,

'NewSKUBridge'[Product ID],

BillToBridge[Bill To ID]

),

"Act Vol", CALCULATE([Total Units Sgls],DATESBETWEEN('Calendar'[Date],MIN('Calendar'[Date])>=MIN(Contracts[Contract Start Date]),MAX('Calendar'[Date])<=CALCULATE(MAX(Contracts[Contract End Date]),USERELATIONSHIP(Contracts[Contract End Date],'Calendar'[Date]))))

),

[Act Vol]

)

Could you please advice how can I fix this? 

Below is the updated data model with inactive relationship between calendar-date field and Contract End Date

@BILearner , Try with Values at Invoice Id or Date level

CALCULATE ([Total Volume],
FILTER (
SalesFact,
SalesFact[INVOICE_DATE]
>= MIN ( Contracts[Contract Start Date] )
),
SalesFact[PRODUCT_ID]
IN VALUES ( Contracts[Product ID] ),
SalesFact[BILL_TO_CUST_ID]
IN VALUES ( Contracts[Bill To ID] )
, values(SalesFact[INVOICE_ID]) //SalesFact[INVOICE_DATE]
)

@amitchandak  Thank you for your response I tried both of your solution with Values(INVOICE_ID)// INVOICE_DATE.

It didn't work, it gave me the exact same result as my previous formula.
