Difference Between Calculate & Filter

[Enan]

Hi Experts,

Need your guidance to understand the behaviour of Filter & Calculate.

I have used below DAX measures to calcualte total Transactions based where quantity =6 and for Jan97.

However when i use the slicer and slect quantity less than 06 it gives blank value for PINK text box (Filter DAX used) but when i nothing changes in Blue Text Box (Calcualte use).

Can you please guide me how it is working.

Below images and DAX are for your inforamtion:

No Slicer SelectedSlicer Value Selected

Total Transaction Jan97 & Qty equals 6 using Filter = CALCULATE(COUNTROWS(

    FILTER(Transactions_Data_Fact,Transactions_Data_Fact[quantity]=6 &&

     Transactions_Data_Fact[year]=1997 &&

     Transactions_Data_Fact[Month] =1)))

Total Transaction Jan97 & Qty equals 6 using Calculate = CALCULATE(COUNTROWS(Transactions_Data_Fact),

Transactions_Data_Fact[quantity]=6,

Transactions_Data_Fact[year]=1997,

Transactions_Data_Fact[Month]=1)

Refer to this sqlbi article: https://www.sqlbi.com/articles/filter-arguments-in-calculate/

To directly try to answer your question, filters statements in CALCULATE that don't explicitly use FILTER are implicitly using FILTER( ALL( Table[Column] ), <condition> ). I.e. your 'using Calculate' version is equivalent to:

= CALCULATE(
    COUNTROWS( Transactions_Data_Fact ),
    FILTER( ALL( Transactions_Data_Fact[quantity] ), Transactions_Data_Fact[quantity] = 6 ),
    FILTER( ALL( Transactions_Data_Fact[year] ), Transactions_Data_Fact[year] = 1997 ),
    FILTER( ALL( Transactions_Data_Fact[Month] ), Transactions_Data_Fact[Month] = 1 )
)
