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:

Best Regards,

Liu Yang

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 )
``````
