Hi, @Anonymous 

Based on your description, I created data to reproduce your scenario. The pbix file is attached in the end.

Table:

Base Date(a calculated table):

Base Date = DISTINCT('Table'[Date])

Compare Date(a calculated table):

Compare Date = DISTINCT('Table'[Date])

You may create three measures as below.

Count of Dimensions = COUNTROWS('Table')

Net variance = 
IF(
    HASONEVALUE('Base Date'[Date])&&HASONEVALUE('Compare Date'[Date]),
    COUNTROWS(
        FILTER(
            'Table',
            [Date]=SELECTEDVALUE('Compare Date'[Date])
        )
    )-
    COUNTROWS(
        FILTER(
            'Table',
            [Date]=SELECTEDVALUE('Base Date'[Date])
        )
    )
)

Actual varaince = 
var _comparetab =
CALCULATETABLE(
    DISTINCT('Table'[Dimension]),
    FILTER(
        ALL('Table'),
        'Table'[Date]=SELECTEDVALUE('Compare Date'[Date])
    )
)
var _basetab = 
CALCULATETABLE(
    DISTINCT('Table'[Dimension]),
    FILTER(
        ALL('Table'),
        'Table'[Date]=SELECTEDVALUE('Base Date'[Date])
    )
)
var _result = 
COUNTROWS(
    FILTER(
        _comparetab,
        NOT([Dimension] in _basetab)
    )
)
return
IF(
    HASONEVALUE('Base Date'[Date])&&HASONEVALUE('Compare Date'[Date]),
    IF(
        ISBLANK(_result),
        0,
        _result
    )
)

Result:

This is the requirement

Hi, @Anonymous 

Based on your requirement, I have modified the data as below. The pbix file is attached in the end.

Base Date(a calculated table):

Base Date = DISTINCT('Table'[Date])

Compare Date(a calculated table):

Compare Date = DISTINCT('Table'[Date])

You may modify the measure as below.

Actual varaince = 
var _comparetab =
CALCULATETABLE(
    DISTINCT('Table'[Dimension]),
    FILTER(
        ALL('Table'),
        'Table'[Date]=SELECTEDVALUE('Compare Date'[Date])
    )
)
var _basetab = 
CALCULATETABLE(
    DISTINCT('Table'[Dimension]),
    FILTER(
        ALL('Table'),
        'Table'[Date]=SELECTEDVALUE('Base Date'[Date])
    )
)
var _result = 
COUNTROWS(
    FILTER(
        _basetab,
        NOT([Dimension] in _comparetab)
    )
)
return
IF(
    HASONEVALUE('Base Date'[Date])&&HASONEVALUE('Compare Date'[Date]),
    IF(
        ISBLANK(_result),
        0,
        _result
    )
)

Hi, count is coming right but I need to variance per employee but data is poping for every employee .

[Anonymous]

I have also replaced the country of A(india ) to A(USA) on 06/01/19

[Anonymous]

Net variance is coming wrong by selecting groups in slicer

Hi, @Anonymous 

You may try the following measure to see if it works.

Actual varaince = 
var _comparetab =
CALCULATETABLE(
    DISTINCT('Table'[Dimension]),
    FILTER(
        ALLSELECTED('Table'),
        'Table'[Date]=SELECTEDVALUE('Compare Date'[Date])
    )
)
var _basetab = 
CALCULATETABLE(
    DISTINCT('Table'[Dimension]),
    FILTER(
        ALLSELECTED('Table'),
        'Table'[Date]=SELECTEDVALUE('Base Date'[Date])
    )
)
var _result = 
COUNTROWS(
    FILTER(
        _basetab,
        NOT([Dimension] in _comparetab)
    )
)
return
IF(
    HASONEVALUE('Base Date'[Date])&&HASONEVALUE('Compare Date'[Date]),
    IF(
        ISBLANK(_result),
        0,
        _result
    )
)

Hi,

Thanks for your help but its not working while comparing 1/1/19 and 6/1/19 its giving different value when selecting india and usa as countries

@Anonymous , refer if this blog can help

https://community.powerbi.com/t5/Community-Blog/Comparing-Data-Across-Date-Ranges/ba-p/823601

You can use single date if needed

[Anonymous]

This completely different for what I am looking for I need to calculate variance and i have many dimesnsion for different dates

[Greg_Deckler]

@Anonymous Not really enough information to go on, please first check if your issue is a common issue listed here: https://community.powerbi.com/t5/Community-Blog/Before-You-Post-Read-This/ba-p/1116882

Also, please see this post regarding How to Get Your Question Answered Quickly: https://community.powerbi.com/t5/Community-Blog/How-to-Get-Your-Question-Answered-Quickly/ba-p/38490

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.

for base date =1/1/2019(A,B) and  compare date=  6/1/2019  (A,B,B,F) ACTUAL VARINANCE =1 as F is not present in 1/1/2019 but actual varaince for  base date = 6/1/2019 (A,B,B,F) and  compair date =1/12019(A,B,) is 0 as both A,B is present in base date

[Anonymous]

I need to calculate actaul variance  and net variance by slected 2 dates from slicer for eg(base date = 1/1/2019 and coampare date = 6/1/2019 actual variance =1 and net =2 but for base date = 6/1/2019 and copare date 1/1/2019 actaul variance =0 and net variance =2)
