Hi @NellF ,

Thanks for your reply, you can try to see if you are using measure instead of column. This might solve your problem.

  I have prepared two solutions to the problem:

  • Use COLUMN to solve this problem

result_column = 
VAR _1 =
    CALCULATE (
        MAX ( 'Table'[Time at Build Place] ),
        FILTER ( 'Table', 'Table'[Index] = EARLIER ( 'Table'[Index] ) - 1 )
    )
VAR _2 = 'Table'[Time at Build Place] - _1
RETURN
    IF ( 'Table'[Index] = 1, BLANK (), _2 )
  • Use MEASURE to solve this problem

result_measure =
VAR _1 =
    CALCULATE (
        MAX ( 'Table'[Time at Build Place] ),
        FILTER (
            ALL ( 'Table' ),
            'Table'[Index]
                = SELECTEDVALUE ( 'Table'[Index] ) - 1
        )
    )
VAR _2 =
    CALCULATE (
        SUM ( 'Table'[Time at Build Place] ),
        FILTER (
            'Table',
            'Table'[Time at Build Place] = SELECTEDVALUE ( 'Table'[Time at Build Place] )
        )
    ) - _1
RETURN
    IF ( SUM ( 'Table'[Index] ) = 1, BLANK (), _2 )

Hi @NellF 

 

Please follow these steps:

  1.        index your table

vyifanwmsft_0-1700812989875.png

  1.        After moving a down one row, the two columns are subtracted. The first line outputs a blank value.

result = 
VAR _1 =
    CALCULATE (
        MAX ( 'Table'[Time at Build Place] ),
        FILTER ( 'Table', 'Table'[Index] = EARLIER ( 'Table'[Index] ) - 1 )
    )
VAR _2 = 'Table'[Time at Build Place] - _1
RETURN
    IF ( 'Table'[Index] = 1, BLANK (), _2 )
  1.         final output.
