Count Documents Issued within Certain Month

Hi nr83 ,

The following is my solution, please point out if it is not right.

1.Create a calculated table by New table under Calculations. Make sure that the new table is not related to the old table.

Slicer = 
DISTINCT (
    SELECTCOLUMNS (
        FILTER ( 'Table', [Workflow Start] <> BLANK () ),
        "YearMonth",
            YEAR ( [Workflow Start] ) & "-"
                & FORMAT ( MONTH ( [Workflow Start] ), "00" )
    )
)

2.Create a measure to count the YearMonth which is selected.

Count YearMonth =
CALCULATE (
    COUNT ( 'Table'[Workflow Start] ),
    FILTER (
        'Table',
        MONTH ( 'Table'[Workflow Start] )
            = VALUE ( RIGHT ( SELECTEDVALUE ( 'Slicer'[YearMonth] ), 2 ) )
            && YEAR ( 'Table'[Workflow Start] )
                = VALUE ( LEFT ( SELECTEDVALUE ( 'Slicer'[YearMonth] ), 4 ) )
    )
)

3.The result is this.
