Using Previousday

Anonymous , It takes the first day from the context on the calendar if not date is selected. so if page has date range of this month, then it gives the last date, last month

You can try

Last Day = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Date]=max('Date'[Date])-1))

Yesterday = CALCULATE([Net], FILTER('Date','Date'[Date] = Today()-1 ) )

Last Day = CALCULATE(sum('Table'[Qty]), dateadd('Date'[Date],-1, day))

Hi Anonymous ,

PREVIOUSDAY function will return a table that contains a column of all dates representing the day that is previous to the first date in the dates column, in the current context. Could you please provide the related formula of measure which involved PREVIOUSDAY function? And what's your final expected result? You can show some sample(fake) data(exclude sensitive data) to explain your requirement, later we can provide you a suitable solution. Thank you.

Best Regards
