Need help Calculate Prior year values working for one other filter

[MaliniBaktha]

Hi , 

I am working on the data where I am calculating the sum of appointments total by prior fiscal year.  to calculate the prior year values , I have used a calculation suggested by this forum, it works fine  when we select year filter, but the moment I select other filter this calculation prior year calculation doesnot hold good. 

How do I correct it ?

This is the calculation I am using to calculate previous year 

calculate(sum('OLD ONE'[COUNT(DISTINCT APT)]),filter(ALL('OLD ONE'),[FISCAL_YEAR_NUM]=SELECTEDVALUE('OLD ONE'[FISCAL_YEAR_NUM])-1))

Now I want this calcualtion to work for other region level filter too . the moment I chose a region filter the prior year filter is not working

Source Data

Previous Year Formula

Result when nothing is selected

Result when 2024 is selected. Please check the prior snapshot for the result of 2023 in the matrix table.

Business Development is selected from Department Slicer.

One more thing before doing the measure I had created the year column from the date column.

Please let me know if the same formula is applicable for your dataset or not.

Hi,

I assume your datamodel does not have calendar dimension table or region dimension table.

One of the best ways is to have those dimension tables, but in case you cannot create those, please try something like below.

expected previous year =
CALCULATE (
    SUM ( 'OLD ONE'[COUNT(DISTINCT APT)] ),
    VALUES ( 'OLD ONE'[Region Name] ),
    FILTER (
        ALL ( 'OLD ONE' ),
        [FISCAL_YEAR_NUM]
            = SELECTEDVALUE ( 'OLD ONE'[FISCAL_YEAR_NUM] ) - 1
    )
)
