Show subsequent data after selecting a filter

Hi, vic3197 

You can try the following methods.
Sample data:

Make a new filter table. Two tables do not establish a relationship directly.
Table:

Slicer = VALUES('Table'[Week])

Measure:

Measure = 
SWITCH (
    TRUE (),
    SELECTEDVALUE ( Slicer[Week] ) = BLANK (), 1,
    SELECTEDVALUE ( 'Table'[Week] ) <= SELECTEDVALUE ( Slicer[Week] )
        && SELECTEDVALUE ( 'Table'[Week] )
            > SELECTEDVALUE ( Slicer[Week] ) - 12, 1,
    0
)

Put Measure into the view and set it equal to 1.

Show all when slicers are not selected. When the slicer is selected, it displays the data for the selected week and the previous eleven weeks.

Is this the result you expect?
