Expressions that yield variant data-type cannot be used to define calculated columns

[Anonymous]

Dear Community,

I have the below formula that is returning the above error - please can you help me?

I'm trying to achieve a column that defines the status of a milestone based on dates. I already created previous formulas that were not working, but I did not get this error. And I am not mixing number and text values, so I can't figure out why is not working. Can you please help me?

Basically I want to define the status of the response milestone, based on the dates (response date, and target date). However and because I have multiple conditions I found easier to use the switch function:

Response Status =

SWITCH(TRUE(),

'main table'[Response Date]< 'main table'[Response_Target_Date], "Succeeded",

'main table'[Response Date]> 'main table'[Response_Target_Date], AND(OR(ISBLANK('main table'[Response Date]),'main table'[Response_Target_Date]<TODAY()),"Noncompliant"),

AND(ISBLANK('main table'[Response Date]),'main table'[Response_Target_Date]>TODAY()),"Response not sent",

"NA")

Thank You!

@Anonymous , Try like

Response Status =

SWITCH(TRUE(),
'main table'[Response Date]< 'main table'[Response_Target_Date], "Succeeded",
AND('main table'[Response Date]> 'main table'[Response_Target_Date], OR(ISBLANK('main table'[Response Date]),'main table'[Response_Target_Date]<TODAY())),"Noncompliant",
AND(ISBLANK('main table'[Response Date]),'main table'[Response_Target_Date]>TODAY()),"Response not sent",
"NA")

@Anonymous hi

the problem is somewhere in this part

'main table'[Response Date]> 'main table'[Response_Target_Date], AND(OR(ISBLANK('main table'[Response Date]),'main table'[Response_Target_Date]<TODAY()),"Noncompliant"),

AND(ISBLANK('main table'[Response Date]),'main table'[Response_Target_Date]>TODAY()),"Response not sent",

I was not able to understand the logic, but I can suppose that you have an incorrect first AND

try

Response Status =

SWITCH(TRUE(),
'main table'[Response Date] < 'main table'[Response_Target_Date], "Succeeded",
'main table'[Response Date] > 'main table'[Response_Target_Date] && 
  (OR(ISBLANK('main table'[Response Date]),'main table'[Response_Target_Date] < TODAY()), "Noncompliant",
AND(ISBLANK('main table'[Response Date]),'main table'[Response_Target_Date] > TODAY()), "Response not sent",
"NA")

Hi az38,

Thanks you for your quick answer. The formula is not giving any error now.

However I have a problem with the Status. As you can see in the reply to amitchandak. Maybe you can help as well.

I am stuck and cannot move further with this.

Thank you!

Hi amitchandak,

Thanx for answering so quick!

The issue is now solved. However the formula is not retrieving the correct status:

AND(ISBLANK('main table'[Response Date]),'main table'[Response_Target_Date]>TODAY()),"Response not sent"

I am getting the "Succeeded" status with the Response Date in blank and the Target Date < Today. 

And if the Target Date is missing it is appearing as " NA", even if the Response Date is blank.

Also if I have a Response Date, but not a Target Date it is appearing as "Noncompliant", which souldn't because if it does not have a target date.

I am realizing that I have a lot of conflicting conditions, and not sure how to proceed further with this.

Thanks for your help!

Hi, @Anonymous 

Is  this your expected result ?

Try calculated column as below:

Response Status = 
IF (
    ISBLANK ( 'main table'[Response_Target_Date] ),
    "N/A",
    IF (
        ISBLANK ( 'main table'[Response Date] )
            && 'main table'[Response_Target_Date] > TODAY (),
        "Response not send",
        IF (
            'main table'[Response Date] <> BLANK ()
                && 'main table'[Response Date] <= TODAY ()
                && 'main table'[Response Date] < 'main table'[Response_Target_Date],
            "Succeeded",
            "Noncompliant"
        )
    )
)

Hi @v-easonf-msft Thanks for your reply. That is exactly what I need. I've just replicate your formula in my pbix and... is working! You don't know how happy I am right now! Thank you so so much for your help!
