Hi  @Anonymous ,

Here are the steps you can follow：

1. Create calculated column.

week = WEEKNUM('Table'[Date],1)

2. Create measure.

Previous Value =
var _week=WEEKNUM(MAX('Table'[Date]),1)
return
CALCULATE(SUM('Table'[Value]),FILTER(ALL('Table'),'Table'[week]=_week-1))

Flag =
var _today=TODAY()
var _week=WEEKNUM(_today,1)
return
IF(
    WEEKNUM(MAX('Table'[Date]),1)=_week-1,1,0)

3. Place [Flag]in Filters, set is=1, apply filter.

4. Result:

Hi,

I am not sure how your data model looks like, but I tried to create a sample pbix file like below.

Please check the below picture and the attached pbix file.

Previous value: =
VAR _currentdate =
    MAX ( Data[Date] )
VAR _previousdate =
    MAXX (
        FILTER ( ALLEXCEPT ( Data, Data[Code] ), Data[Date] < _currentdate ),
        Data[Date]
    )
VAR result =
    CALCULATE (
        [Current value:],
        FILTER ( ALL ( Data[Date], Data[Label] ), Data[Date] = _previousdate )
    )
RETURN
    IF ( HASONEVALUE ( Data[Label] ), result )
