I am trying to create new measures that will only show the data value of the Last day every month and another measure will show the data value of every week Saturday in Power BI.
Many thanks in Advance.
The data is continuing and the next series of data will appended data wise
Output:
Need to create a measure which will show only last day of the Week value ( Example- Saturday is my Last of the Week and Count numbers I need to see as output)
Similarly for Month - Last day of the Month I need to see the Numbers of each service.

Do you have Calendar table mark as "Date Table", which is connected by relationship to your Table? If so, then you can use ENDOFMONTH ( 'Calendar'[issue_date] ) to get lastDateOfMonth
then simply:
ShowValueAtLastDayOfMonth =
calculate( sum(Table[Total sale]),
KEEPFILTERS(
filter(ALL('Calendar'[issue_date]),
'Calendar'[issue_date] = ENDOFMONTH ( 'Calendar'[issue_date] )
)
)
)
ShowOnlyOnSaturday =
calculate(sum(Table[Total sale]), KEEPFILTERS( FLITER(ALL('Calendar[issue_date]),
WEEKDAY ( SELECTEDVALUE('Calendar'[issue_date])) = 7 )))
Without a "Date Table" we need to replace 'Calendar'[issue_date] with your Table[Date] and ENDOFMONTH with:
VAR LastDateVisible =
CALCULATE ( MAX ( 'Table'[Date] ) )
VAR LastYearVisible =
YEAR ( LastDateVisible )
VAR LastMonthVisible =
MONTH ( LastDateVisible )
VAR DaysInMonth =
FILTER (
ALL ( 'Table'[Date] ),
YEAR ( 'Table'[Date] ) = LastYearVisible
&& MONTH ( 'Table'[Date] ) = LastMonthVisible
)
VAR LastDayInMonth =
MAXX (
DaysInMonth,
'Table'[Date]
)
VAR Result =
CALCULATETABLE (
VALUES ( 'Table'[Date] ),
'Table'[Date] = LastDayInMonth
)
RETURN
Result
