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

[DrewCarousel]

Dear Community,

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

I'm trying to achieve a column that gives me a date & time field.

Formats:

Channel = Text

Parent Account = Text

Submitted = Date

SLA = Date&Time

CalcSLA = if('Master Table'[Channel]="IE Own Network",if(OR('Master Table'[Parent Account]="CUSTOMER A",'Master Table'[Parent Account]="CUSTOMER B"),format('Master Table'[Submitted],"General Number")+0.729167,if('Master Table'[Parent Account]="CUSTOMER C",format('Master Table'[Submitted],"General Number")+0.729167,format('Master Table'[Submitted],"General Number")+0.5)),if('Master Table'[Channel]="UK Own Network - NIGHT",format('Master Table'[Submitted],"General Number")+format('Master Table'[SLA Temp],"General Number"),format('Master Table'[SLA],"General Number")))

Hi @DrewCarousel ,

You could refer to the following DAX:

CalcSLA =
IF (
    'Master Table'[Channel] = "IE Own Network",
    IF (
        OR (
            'Master Table'[Parent Account] = "CUSTOMER A",
            'Master Table'[Parent Account] = "CUSTOMER B"
        ),
        VALUE ( FORMAT ( 'Master Table'[Submitted], "General Number" ) ) + 0.729167,
        IF (
            'Master Table'[Parent Account] = "CUSTOMER C",
            VALUE ( FORMAT ( 'Master Table'[Submitted], "General Number" ) ) + 0.729167,
            VALUE ( FORMAT ( 'Master Table'[Submitted], "General Number" ) ) + 0.5
        )
    ),
    IF (
        'Master Table'[Channel] = "UK Own Network - NIGHT",
        VALUE (
            FORMAT ( 'Master Table'[Submitted], "General Number" )
                + FORMAT ( 'Master Table'[SLA Temp], "General Number" )
        ),
        VALUE ( FORMAT ( 'Master Table'[SLA Temp], "General Number" ) )
    )
)

@DrewCarousel , Make sure all of them return text add & "" to make sure in all if and else

Hi Amit,

Thank you for this.

Please could you edit my original formula or give more guidance on where to place the &"".

Also to confirm, this will still add the decimal numbers to the original dates? To reiterate, I'm looking to get a date and time output.

Best regards,

Drew

@DrewCarousel : considering breaking the formula into multiple measures (a,b,c) so you can know exactly where the error is occurring. Then have your last output measure equal measure A + measure B + Measure C.
