Power Query Date Column: to display month based on an existing column

[nic2023]

We are currently in month of August, I have a raw data with a column contains Dates ranged from later June to all possible July dates, the majority of the dates are July.  

The desired outcome is to add a column to show all entries (can be June or July) with a standardzied "Jul-23" as the majority dates within tha report, i.e. those entries dated with June also flagged as "Jul-23"

Is there any formula related to show MMM-YY from averged date or majority date point of view?

Thanks in advance.

Hi @nic2023 ,

Raw data:

Final result:

Steps of the soltuion:

1.Add a custom column to return MonthYear based on the date column.

2.Group by the date column.

3.Add a custom to return the majority of the month year.

4.Fill down/up the monthyear.

5.Remove unneeded columns and expand the all rows, you will get the result.

Hi Stephen, Would you be able to elaborate more on the above step 5? How to 'expand all rows"? 

5.Remove unneeded columns and expand the all rows

Thank you so much!

@nic2023  I hope this helps you. Thank You.

Create Custom Column
MMM YY =
Date.ToText(#date(Date.Year([DATETIME]), Date.Month([DATETIME]), Date.Day([DATETIME])), [Format="MMM-yy", Culture="de-DE"])

Note :
 change Culture="de-DE" based on your Region and location.

Yes, the Jul-23 can be populated as advised.

However the June dated entries are also show their real month as Jun-23 

The desired outcome is to show all entries with Jul-23 as the majority dates within tha report. 

Is there any formula related to show MMM-YY from averged date or majority date?
