Differentiate operations

[Tommyvhod]

Hello all

I have a formula which calculates the days between two operations:

Aging = var _time =

    MAX(Data[Datum trans])

        VAR _maxLastTime  =

        CALCULATE(MAX(Data[Datum trans]),

        FILTER(ALLEXCEPT(Data, Data[ID]), Data[Datum trans] < _time)

        )

    VAR _datedif =

    DATEDIFF(_maxLastTime,_time,DAY)

    Return

    IF(_datedif >0,_datedif,0)

The problem here is that if I have the same date on the last 4 operations and x day before those all the 4 last operations shows x day difference.

I am wondering how could I add another line differenciating the number of the operation ( its always ascending - eg. operation 1, 2 , 5 , 10, 20, etc)

Thank you

Thank you. Yes the index column was a good Idea. What I also changed is the

IF(_datedif >0,_datedif,0)

To _datedif, Blank()) so the visual wont show unecessary columns

Hi @Tommyvhod ,

Based on your description, I have created a simple sample:

Please try:

add an index column:

Then apply the measure:

Aging = 
var _time =
    MAX(Data[Datum trans])
var _index = MAX('Data'[Index])
        VAR _maxLastTime  =
        CALCULATE(MAX(Data[Datum trans]),
        FILTER(ALLEXCEPT(Data, Data[ID]), [Index]=_index-1)
        )
    VAR _datedif =
    DATEDIFF(_maxLastTime,_time,DAY)
    Return
    IF(_datedif >0,_datedif,0)

Final output:

Best Regards,
