Comparing dates between two unrelated fact tables (many to many)

[SeanGannon]

We have two fact tables - Payments and Customer Contacts.  We would like to find out how many Payments are made within 6 days of a Customer Contact (a call or email from a collections staff member).  Payments and Customer Contacts both relate to DimAccount, and both will have many records for each account.

FactPayments

DimAccountID

PaymentDate

PaymentAmount

FactCustomerContact

DimAccountID

DimCampaignID

ContactDate

This measure uses TREATAS to force this relationship, this allows be to display both dates together in a table.  

Payment = CALCULATE(SUMX(Payments, Payments[Payment Amount]),TREATAS(VALUES('Customer Contacts'[DimCustomerID]),Payments[DimCustomerID]))

But I can't seem to figure out how to filter this measure to only show Payments where the DATEDIFF between these dates is between 0 and 6.

Thanks!

Hi @SeanGannon ,

Can you share some sample data?

@SeanGannon , one the way is to get the contract date in Fact payment

a new column

Con date= maxx(filter(Contract, Contract[DimAccountID] = payment[DimAccountID] && contract[ContactDate]< Payment[Payment Date]), Payment[Payment Date])

now you can only work with payment fact

countx(filter(payment, payment[Payment Date]<= [con date] +6 && payment[Payment Date]>= [con date] ), [DimAccountID])

There are (potentially) many contacts per payment, won't this force repeating records into FactPayment?
