Anonymous this was to be done in PQ.
For DAX use this
Column = DATE('Table'[Year],'Table'[Month Number],1)
Here for the last date or maximum date, I want the last day of month instead of first day, eg if my data lies between Jan 2023 to Jan 2024, I want all records between Jan 2023 to Dec 2023 to show date for first day of month(MMM/01/YYYY) except the records having date in Jan 2024 which I want to show as last day of month(01/31/2024).

Community ChampionHi, last day of month you can achieve this way:
Date.EndOfMonth(#date([Year],[Month Number],1))I don't want the enddate for all the records, only for the records having last(latest) month and year.

For future requests, provide sample data as table so we can copy/paste (see note below my comment) and expected result based on sample data please.
