Current week data compare previous data

Hi Anonymous ,

I created a sample pbix file(see attachment) for you, please check whether that is what you want.

1. Create a custom column with the date which the date is get from

2. Append these two queries from different two dates in Power Query Editor

3. Create two measures to get the item and count separately

Item = 
VAR _mindate =
    DATE ( 2021, 6, 17 ) 
VAR _maxdate =
   DATE ( 2021, 6, 24 ) 
VAR _tab1 =
    CALCULATETABLE (
        VALUES ( 'New'[ID] ),
        FILTER ( ALLSELECTED ( 'New' ), 'New'[Date] = _mindate )
    )
VAR _tab2 =
    CALCULATETABLE (
        VALUES ( 'New'[ID] ),
        FILTER ( ALLSELECTED ( 'New' ), 'New'[Date] = _maxdate )
    )
VAR _tab3 =
    EXCEPT ( _tab1, _tab2 )
VAR _tab4 =
    EXCEPT ( _tab2, _tab1 )
RETURN
    IF (
        SELECTEDVALUE ( 'New'[ID] ) IN _tab3,
        "MOD",
        IF ( SELECTEDVALUE ( 'New'[ID] ) IN _tab4, "FDD", BLANK () )
    )

Count = 
CALCULATE (
    COUNT ( 'New'[ID] ),
    FILTER ( ALLSELECTED ( 'New'[ID] ), NOT ( ISBLANK ( [Item] ) ) )
)

Best Regards
