DAX Error when using If Statement with DateAdd

https://1drv.ms/u/s!AjIGh95acxebg6JDCZEPNu4K7yIYQg?e=i1Vuqa  - PBIX File

 

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
DATEADD
if statement

    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]
        )

    We want to help you but your description is too vaugue. Please write it again clearly.

    Please DON'T copy & paste your DAX that does not work and expect us to fathom what you want to do. That is a bit crazy. 😀

    Please just give a simple non technical functional decscription of what you want, then let us suggest the solution. Thank you.

    Provide example input data as table text (not a screen print) so we can import the data to build a solution for you.
    Also provide the example desired output, with a clear description of the process flow.
    Remember not to share private data ... we don't want you to get into trouble. 😧
    Take time and care to use the same table and field names in the input, output and description so we can understand your problem and help you.
    Try keep it simple and ask one question per ticket.
    You will get a quick response if you put time, care and effort into writing clear problem descriptions.

    Vaugue descriptions can waste your time and ourtime.

    Look foward to helping you when the above information is forthcoming

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

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