TopN returns different results when adding additional column

I am generating the following table below which just displays week number, total for the week (sum of sales), and a measure for calculating 8-week Running Total:

My problem is that, when I add the Week Description column (which is just text column from data source), the 8-week running total is no longer returning the correct results and is just the same as Total for the Week:

lancea_1-1624856783490.png

My formula for the 8-week Running Total is below:

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] ), Last8Weeks )

 

Why does this happen and how can I fix this?

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:

@lancea , In such case better to have separate week or date table, That will allow you to all or allselected of table then column

 

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

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 *:*)

@lancea , change topN like and try

 

TOPN(10,filter(all(WeekTable[Week]), WeekTable[Week] <=max(WeekTable[Week])),WeekTable[Week],DESC)

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 )
