Hi, I have a data looks like this:

 I would like to create a three new columns (like shown on the right of the picture),

the first column should contain the first reason of error (type of error according to importance, should be number 3 as it is the most important).

Second column should contains the second reason of error ( should be number 2)

And thrid column should contains the third reason.

Hi @ab00sa7i ,

I create the table as you mentioned.

Then I think you can create three calculated columns.

reason1 = 
VAR _max =
    CALCULATE (
        MAX ( 'Table'[number of repeted error with important degree] ),
        ALLEXCEPT ( 'Table', 'Table'[id] )
    )
RETURN
    CALCULATE (
        SELECTEDVALUE ( 'Table'[error type] ),
        ALLSELECTED ( 'Table' ),
        'Table'[number of repeted error with important degree] = _max
    )

reason2 = 
VAR _max =
    CALCULATE (
        MAX ( 'Table'[number of repeted error with important degree] ),
        ALLEXCEPT ( 'Table', 'Table'[id] )
    )
VAR _next =
    CALCULATE (
        MAX ( 'Table'[number of repeted error with important degree] ),
        FILTER (
            ALLSELECTED ( 'Table' ),
            'Table'[id] = EARLIER ( 'Table'[id] )
                && 'Table'[number of repeted error with important degree] < _max
        )
    )
RETURN
    CALCULATE (
        SELECTEDVALUE ( 'Table'[error type] ),
        ALLSELECTED ( 'Table' ),
        'Table'[number of repeted error with important degree] = _next
    )

reason3 = 
VAR _min =
    CALCULATE (
        MIN ( 'Table'[number of repeted error with important degree] ),
        ALLEXCEPT ( 'Table', 'Table'[id] )
    )
RETURN
    CALCULATE (
        SELECTEDVALUE ( 'Table'[error type] ),
        ALLSELECTED ( 'Table' ),
        'Table'[number of repeted error with important degree] = _min
    )

Finally you will get what you want.

Best Regards
