Calculate values for each month based on a date/time column

[Anonymous]

How can I create a measure to calculate 'PPV= (Sum of TRUE COL for June 2020)/(Sum of TRUE COL for June 2020+ Sum of FALSE COL for June 2020)'?.  June 2020 is just an example. The formula needs to be applied to all the date/time and PPV should be different for different months and years. I need to visualize this calculated PPV to show changes every month and year.

@Anonymous , Try a measure like this

divide(sum(Table[True Col]),sum(Table[True Col]) + sum(Table[False Col]))

For date filter better join to date filter an use that.

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :

Appreciate your Kudos.

Hi @Anonymous ,

This formula is dynamic and should work for all periods selected (one month, several months, several years).

PPV =

var TrueCol = SUM(Sheet1[True Col])

var FalseCol = SUM(Sheet1[False Col])

var Total = TrueCol + FalseCol

RETURN

DIVIDE(TrueCol,Total)

Cheers,
