Hi PB Community

i am trying to use If statement in my DAX expression as below

new date1 = IF('bi v_shift'[shiftName] = "night" && 'bi v_shift'[startOffsetMinutes] > 55, DATEADD('bi v_shift'[dateTimeNearestHour],-1,DAY),'bi v_shift'[dateTimeNearestHour]).

I get the below error

"A single value for column 'dateTimeNearestHour' in table 'bi v_shift' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count"

All i want is if Shift name is "night" and StartOffsetMinutes is greater than 55 minutes, then the Date in Datetimenearesthour should go back by 1 day.

FYI Datetimenearesthour is Date/time type, i changed it to DAte time still getting errors.

I am fine with Either Column or Measure

replace the following expression
DATEADD('bi v_shift'[dateTimeNearestHour],-1,DAY)
with
bi v_shift'[dateTimeNearestHour]-1

[wasirafi]

still the same error

[Ahmedx]

remove these ( )
I also advise you to give columns and tables a normal name without spaces or hyphens.

Ahmed,

I only removed "()" not the content inside it, as that is the second IF criteria.

I did note your point on not having Spaces and Hypen in the name of the table. The Dataset is owned by 3rd party and i cannot influence that.

The error still remains

[Ahmedx]

Is this columns in this table or in another?

[wasirafi]

i just attached the PBIX file....if that helps

[Ahmedx · Accepted solution]

pls try this

Column = IF(
        'bi v_shift'[shiftName]= "night"&& 
        'bi v_shift'[startOffsetMinutes]>55,
        'bi v_shift'[dateTimeNearestHour].[Date]-1,
        'bi v_shift'[dateTimeNearestHour].[Date]
        )

Thanks @Ahmedx  You were very helpful

All the columns are from the same Table.
