Trouble formatting dates for T/F Check

[tabil]

I have a date column with LatestCompletion m/d/yy. I used table[LatestCompletion].[Month] to separate out the months and did the same with the years. I want to compare the month and year to see previous month's data, but I can't format the resulting [Month] column. It only gives me the months as full text (January, etc.) and I get an #ERROR! when I try to change the data type or use format(). Is there a better way to do this?

Hi  @tabil ,

Create a column similarly as below:

Month = MONTH('Table (2)'[Date])

And you will see:

@tabil , if you have date, best is to use time intelligence with date table

example

MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD('Date'[Date]))
last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-1,MONTH)))

last year MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-12,MONTH)))
Previous year Month Sales = CALCULATE(SUM(Sales[Sales Amount]),previousmonth(dateadd('Date'[Date],-11,MONTH)))

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 :radacad sqlbi My Video Series Appreciate your Kudos.
