SAMEPERIODLASTYEAR with previous date filter

[DavidEg]

Hi,

I have a table tickets, with two dates. Opening Date and solution Date. I relate them through a calendar table.

N_TicketsOpening = CALCULATE (COUNT (CCBI_vwTickets [TicketId]), CCBI_vwTickets [OpeningDate])

And I need a measure that counts the tickets from the same previous period.

I tried

N_TicketsOpening_LY = CALCULATE (COUNT (CCBI_vwTickets [TicketId]), SAMEPERIODLASTYEAR (CCBI_vwTickets [OpeningDate]))

but it doesn't work, it doesn't show data.

I put a page filter that selects the last 12 calendar months.

Hi @DavidEg 

My Sample:

I add YearMonth into Page filter and select 202101 and 202112.

Please try my measure:

N_TicketsOpening_LY = 
VAR _CurYear = YEAR(MAX(CCBI_vwTickets[OpeningDate]))
Return
CALCULATE(COUNT(CCBI_vwTickets[TicketId]),FILTER(ALL(CCBI_vwTickets),YEAR(CCBI_vwTickets[OpeningDate])=_CurYear-1))

Result is as below.

If this reply still couldn't help you solve your problem, please show me a sample like what you are dealing with by your Onedrive for Business.

This will make it easier for me to understand your requirement.

Best Regards,

@DavidEg - If you are using a page filter, then you will not be able to get those rows back via DAX using ALL or ALLEXCEPT, etc. Page filters pre-filter the rows available to DAX calculations.

Sorry, having trouble following, can you post sample data as text and expected output?
