    Hi lancea,

     

    Try measure as:

    8wk_Total =
VAR LastWeek = MAX ( Query1[Week] )
VAR Last8Weeks = TOPN (8, FILTER ( ALL ( Query1[Week] ), Query1[Week] <= LastWeek ), Query1[Week], DESC)
RETURN
CALCULATE ( SUM ( Query1[Sales] ), FILTER(ALL('Query1'),Query1[Week] IN Last8Weeks )

    Here is the output:

Sorry, this does not work and returns error in the formula:

 

For reference, I created a Week_Table using the formula:

Week_Table = UNION(VALUES(Query1[Week]),{""})
 
Then I created a 1:* relationship between Query1 and Week_Table (the only other alternative is *:*)

    It works now but unfortunately, I still get the same results:

     

     

    Here is my formula for 8wk_separate:

     

    8wk_separate = VAR LastWeek = MAX ( Query1[Week] )
    VAR Last8Weeks = TOPN(10,filter(all(Week_Table[Week]), Week_Table[Week] <=max(Week_Table[Week])),Week_Table[Week],DESC)
    RETURN
    CALCULATE ( SUM ( Query1[Total PO lines due this week (CRD)] ), Last8Weeks )
