    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" ) )
    )
)

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.
