11 Week Look Ahead Dynamic Calculation

Hi, Anonymous 

You can create this summary table, or use it as a table filter in other measures.

Like this:

Two columns first:

weekday = WEEKDAY([Date],2)

weeknum = WEEKNUM([Date],1)

Table1 = 
VAR a =
    MAXX ( FILTER ( ALL ( 'Table' ), [Date] = TODAY () ), [weeknum] )
RETURN
    SUMMARIZE (
        FILTER (
            ALL ( 'Table' ),
            [weeknum]
                = MAXX ( FILTER ( ALL ( 'Table' ), [weeknum] = a + 11 ), [weeknum] )
        ),
        [Date],
        [weekday],
        [weeknum]
    )

HelloAnonymous 

Because I don't know what your requirements are used for, so I just created a table.

You need to create table by new table button.

Reference:

SUMMARIZE function (DAX) - DAX | Microsoft Docs

Can you share your formula and error screenshots in the report? If you can describe in detail how your needs are presented in the report visual, I can help you more specifically.
