You can do it with either of the below approaches based on your broader requirement:
- Current week filter in information link
- Current week filter in each visualization
- Create a dummy data table with a value say "Show" and in your main data table create calculated column such as case when (Month([Date])=Month(DateTimeNow())) and (Year([Date])=Year(DateTimeNow())) and (Week([Date])=Week(DateTimeNow())) then "Show" else "Hide" end.
Then apply data relation on this column and in filters do include filtered rows only. So everytime it will show data for current week only whenever the report is opened/refreshed.
