Finding the difference between date values in the same row of different column within a Matrix

[Merle]

Hi,

I will greatly appreciate help in finding the difference between dates values within a matrix inorder to determine WoW%.

Desired out put in screen shot below.

This visual was obtain using the new tool New Calculation(fx) but has limitation of not being able to export data with these calculations.

These are the calculation used.

Versus previous = [Purchase Complete] - PREVIOUS([Purchase Complete], COLUMNS).

WOW = FORMAT(DIVIDE([Versus previous], PREVIOUS([Purchase Complete],COLUMNS),0),"#,#0%").

@Joe_Barry Thanks for your contribution on this thread.

Hi @Merle ,

You can create a measure as below to get it, please find the details in the attachment.

WOW = 
VAR _pcdate =
    SELECTEDVALUE ( 'Table'[Purchase Complete] )
VAR _category =
    SELECTEDVALUE ( 'Table'[Category] )
VAR _predate =
    CALCULATE (
        MAX ( 'Table'[Purchase Complete] ),
        FILTER (
            ALLSELECTED ( 'Table' ),
            'Table'[Category] = _category
                && 'Table'[Purchase Complete] < _pcdate
        )
    )
VAR _prevalue =
    CALCULATE (
        SUM ( 'Table'[Sales] ),
        FILTER (
            ALLSELECTED ( 'Table' ),
            'Table'[Category] = _category
                && 'Table'[Purchase Complete] = _predate
        )
    )
RETURN
    DIVIDE ( SUM ( 'Table'[Sales] ) - _prevalue, _prevalue )

Hi Joe,

Thanks for your response. Dax Formula used is giving the same value as the date column not the difference between the column dates of the previous. Is there a different way to format this formula? Thank you.

Hi @v-yiruan-msft,

Thank you again for your solution to my previous question. 

I have encountered an issue in finding the Conversion rate (CR) of two measures between dates. Can you please assist me with this?

CR Formula = Upgrade / Signups

Expected results:

I have tried your dax formula with a slight modification:

This is my result, it is only calculating the first date between Upgrade and Signups.
