M solution converted to DAX

Good day beautiful people,

 

I need a help with below solution, for now it is made in PQ. This is just one piece of bigger query, which unfortunately is causing some issues with performance so I would like to switch from PQ to DAX.

 

Date format: d/m/yyyy

 

What I need?

IDAging_Start_DateEnd_Date
ABC1231/1/20221/5/2022

 

Above table contains about 10k rows with unique IDs and dates for each.

What I need to present on visualization is how many IDs were aged per month. Main problem is that I have only start_date and end_date, so if my filters are between 1/2/2022 - 4/1/2022 this ID will be ignored or I will just see data for January and May.

 

I need to see data for Jan 1st, Feb 1st, Mar 1st, Apr 1st and May 1st (1 per month).

 

I'm using below PQ solution which works amazing but I would like to get rid of heavy calculations (merges etc.) from PQ and focus on DAX only.

 

let

AllDates = {Number.From([Aging_Start_Date])..Number.From([End_Date])},

 

StofMonthDates =

List.Distinct(

List.Transform(

AllDates, each Date.StartOfMonth(Date.From(_))
)
)

in
StofMonthDates

Is there a way to receive similar result as with above query? Sample of the result is presented below.

 

IDAging_Start_DateEnd_Date
ABC1231/1/20221/5/2022

 

After query will be transformed to:

 

IDStofMonthDates
ABC1231/1/2022
ABC1231/2/2022
ABC1231/3/2022
ABC1231/4/2022
ABC1231/5/2022

 

Edit: I can't center the tables, sorry for this. HTML errors.

@Magistralis , refer to the file of the blog. Both have little bit different approch

Absolutely fantastic solution!
It's quite simple when you look at it but my brain could not figure it out.

 

Thank you!
