    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.

Thank you! Ok I am very green in Power BI and completely self taught. What is a summary table? I was able to successfully create the first 2 columns as you listed above the Weekday and Weeknum columns. I went to add a new table and when I got to this portion: ( 'Table' ), [Date]

it gave me an error. I was trying to load my Scheduled Start Date table in that spot but it gave me a syntax error. It is loading 'Scheduled Start Date'.Date so I am thinking I am doing something wrong but it is making me select .Date. Hopefully that makes sense.
