Calculating difference between consecutive rows

‎10-18-2018 01:41 PM

Hi, I am new to Bi and having a hard time in calculating the difference between consecutive rows for a particular ID.

I want to caculate the difference between consecutive volume for a particular "Unique ID". 

As the ID changes, the cumulative difference calculation should correspond to that particular "Unique ID"

 

Thnaks in advance.

Hi @hmeegada,

 

1. Add an index in the Query Editor. 

2. Add a calculated column with the formula below.

Column =
VAR currentIndex = [Index]
VAR currentVolume = [Volume.Volume]
VAR lastVolume =
    CALCULATE (
        MIN ( Table1[Volume.Volume] ),
        FILTER (
            ALLEXCEPT ( 'Table1', Table1[Unique ID] ),
            Table1[Index]
                = currentIndex - 1
        )
    )
RETURN
    IF ( ISBLANK ( lastVolume ), 0, currentVolume - lastVolume )

Hi @hmeegada,

 

What's the expected result? Since the "Unique" is unique, you can just calculate the number of "Unique".

[Unique]    count('table'[Unique])

Hi,  I have provided a sample data below for your reference and the last column is the expected result

 

The difference between consecutive rows should continue for a particular Unique ID and as soon as the Unique ID changes, the difference between consecutive rows should correspond to that particular Unique ID.

Hi @hmeegada,

 

1. Add an index in the Query Editor. 

2. Add a calculated column with the formula below.

Column =
VAR currentIndex = [Index]
VAR currentVolume = [Volume.Volume]
VAR lastVolume =
    CALCULATE (
        MIN ( Table1[Volume.Volume] ),
        FILTER (
            ALLEXCEPT ( 'Table1', Table1[Unique ID] ),
            Table1[Index]
                = currentIndex - 1
        )
    )
RETURN
    IF ( ISBLANK ( lastVolume ), 0, currentVolume - lastVolume )
