"-- get a list of all loans on both lists
VAT Onboth = INTESECT( ApplicationsNotBlank, AssignmentsBlank)"

 

Just to make sure this is "VAR" on both and "INTERSECT"

 

I have done exactly that, the table actually loads with column names, but no data.

 

 

Thank you,

Sorry about the typo.  Yes of course INTESECT should be INTERSECT.

 

I have created this example you. So you can look at the data, relationships and data measure
Download this example 

 

This counts the number of loans that have blank TableA[AssignedDate] and not blank TableB[ApplicationDate].

Note only loans 2, 4 and 7 fullfill this condition. So My count = 3.

 

My counts =


-- get a list of all loans with blank assignments on TableA
VAR AssignmentsBlank =
CALCULATETABLE(VALUES(TableA[LoanID]),
FILTER(ALL(TableA),
TableA[AssignedDate] = BLANK() ))

-- get a list of all loans with application dates on TableB
VAR ApplicationsNotBlank =
CALCULATETABLE(VALUES(TableB[LoanID]),
FILTER(ALL(TableB),
TableB[ApplicationDate] <> BLANK() ))

-- get a list of all loans on both lists
VAR Onboth = INTERSECT(ApplicationsNotBlank, AssignmentsBlank)

RETURN
-- counts loans on both
COUNTROWS(Onboth)

    I accept that this would probably work in most scenarios. However, I think there may be some limitations regarding our SQL queries.

     

    I can do the first part by itself and it will create a table, I can also do the same with the 2nd table.

     

    When I do both and try to intersect, nothing populates.
