Hi Team,

I am trying to create the dax for the Maximum date in the previous month. Could you please share your idea?

Hi @Neel98 , 
Hope you have a datedimension table in your data set, if not create that first and create a one to many relationship from your date table to this table and create the below measure. 


CALCULATE( 
          MAX(Report Date),
          DATEADD('Date Dimension'[date],-1,MONTH)
)

month = CALCULATE(MAX('date'[Date]), PREVIOUSMONTH('date'[Date]))
  • MAX('date'[Date]): This function calculates the maximum date from the 'Date' column of your 'date' table.
  • PREVIOUSMONTH('date'[Date]): This function returns a table containing dates from the previous month, considering all dates in the 'Date' column of your 'date' table.
  • CALCULATE: This function evaluates an expression in a modified filter context.

So, when you use CALCULATE with MAX and PREVIOUSMONTH, you're instructing Power BI to calculate the maximum date from the previous month based on the dates in your 'date' table. Your measure will dynamically adjust as the current month changes, always showing the maximum date from the previous month.

This DAX measure should work effectively for your requirement.
