Logical Count Function.

Hi again TSP

Please provide screen prints of the tables and columns next time.

You knew what you meant, but it was not 100% clear to me from your text.

I have added comments to this measure so hopefully you can fathom the solution now, but ask for more help if needed

My count =

-- 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
VAT Onboth = INTESECT( ApplicationsNotBlank, AssignmentsBlank)

RETURN

-- counts loans on both
COUNTROWS(Onboth)

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 =

This works almost exactly how I need it to, but I think I need to specify that the  loan "has" to have an application date. Would I include that filter in the 2nd VAR?

Thank  you for your help,

Hi again TPN

Thank you for your kudos, I enjoyed helping you during lockdown

Sorry, I just assumed all the applications would have an application date.

You can change the 2nd var using CALCULATETABLE with FILTER to just get a list of applications with an application date, like this ...

My count =

VAR AssignedLoans =
CALCULATETABLE(VALUES(LoanTable[LoanID]),
FILTER(ALL(LoanTable),
LoanTable[AssignedDate] <> BLANK() ))

VAR Applications =
CALCULATETABLE(VALUES(ApplicationsTable[LoanID]),
FILTER(ALL(ApplicationsTable),
ApplicationsTable[AppliedDate] <> BLANK() ))

RETURN
COUNTROWS(
EXCEPT( Applications, AssignedLoans)
)

See below: The original formula worked closely, but I had to add a filter to the graph to get it to work.

Now this is what I have, and the tables and counters are not populating.

To reiderate: When Assigned Date IS Blank, then count loans that have an application date.

"-- 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,

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.
