    Hi cris1196 

    The following shall return unique count of customers. 

    Common Customers =
VAR T1 =
    CALCULATETABLE (
        VALUES ( 'Table'[Cutomer] ),
        'Table'[first_order] = "True",
        'Table'[YearMonth] = 202201
    )
VAR T2 =
    CALCULATETABLE (
        VALUES ( 'Table'[Cutomer] ),
        'Table'[Day] = 1,
        'Table'[YearMonth] = 202201
    )
RETURN
    COUNTROWS ( INTERSECT ( T2, T1 ) )
    New Customers =
VAR T1 =
    CALCULATETABLE (
        VALUES ( 'Table'[Cutomer] ),
        'Table'[first_order] = "True",
        'Table'[YearMonth] = 202201
    )
VAR T2 =
    CALCULATETABLE (
        VALUES ( 'Table'[Cutomer] ),
        'Table'[Day] = 1,
        'Table'[YearMonth] = 202201
    )
RETURN
    COUNTROWS ( EXCEPT ( T2, T1 ) )

I was hopping that you explain what are trying to achieve not how are you trying to achieve it. However there is a chance that I correctly guessed your requirement. It could be much simpler than you might think. Please try

Common Customers =
VAR CurrentMonth =
    SELECTEDVALUE ( 'Table'[YearMonth] )
VAR T1 =
    CALCULATETABLE (
        VALUES ( 'Table'[Cutomer] ),
        'Table'[first_order] = "True",
        'Table'[YearMonth] = CurrentMonth - 1,
        ALL ( 'Table'[Day] )
    )
VAR T2 =
    VALUES ( 'Table'[Cutomer] )
RETURN
    COUNTROWS ( INTERSECT ( T2, T1 ) )
