Hi @Anonymous ,

Total =
SWITCH (
    MAX ( 'Table (2)'[Category] ),
    "Count A", COUNT ( 'Table'[Col A] ),
    "Sum B", SUM ( 'Table'[Col B] )
)

Previous Month =
SWITCH (
    MAX ( 'Table (2)'[Category] ),
    "Count A",
        CALCULATE (
            COUNT ( 'Table'[Col A] ),
            FILTER ( 'Table', DATEDIFF ( 'Table'[DATE], TODAY (), MONTH ) = 0 )
        ),
    "Sum B",
        CALCULATE (
            SUM ( 'Table'[Col B] ),
            FILTER ( 'Table', DATEDIFF ( 'Table'[DATE], TODAY (), MONTH ) = 0 )
        )
)

Best Regards,

@Anonymous , have tried time intelligence with date table

example

MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD('Date'[Date]))
last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-1,MONTH)))

diff = [MTD Sales]-[last MTD Sales]
