    You could try either of these measure expressions

     

    TimeDiff = SUMX(Table, Table[TimeColumn1] - Table[TimeColumn2]

     

    or


    TimeDiff = SUMX(Table, DATEDIFF(Table[TimeColumn1], Table[TimeColumn2], MINUTE))

     

    If you make a table visual with both time columns, you should see the difference when you add the measure.  Or you could use the aggregate, maybe switching to AVERAGEX, MAXX, etc. depending on what you are looking for.

     

    Also, there are probably more impactful ways to reduce the file size of your model.

     

    If this works for you, please mark it as the solution.  Kudos are appreciated too.  Please let me know if not.

    Regards,

I tried that measure and when I put it in a table it only gives one value. I am trying to replicate the following column as a DAX measure:

 

 This was calculated using the following calculation:

 

Start Time Variance =
DATEDIFF('bv AFKO: Order Header Data PP Orders'[GSUZS_SIMP_TM: (GC) Scheduled Start (Time)] , 'bv AFKO: Order Header Data PP Orders'[GSUZI_SIMP_TM: (GC) Actual start time] , MINUTE) / 60
 
The columns in the calculation are the following:
