Logical Count Function.

I am trying to calclulate the following: When a certain date is blank, count a related date.   IF(IsBlank(A Date)          ,COUNT(B Date)                      ,Blank()   *This is a direct query...

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.

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 =


    -- 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)

    "-- 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.
