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:
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:
If you still have some question, please don't hesitate to let me known.

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)
8wk_Total =
VAR LastWeek =
MAX ( Query1[Week] )
VAR Last8Weeks =
TOPN (
8,
FILTER ( ALL ( Query1 ), Query1[Week] <= LastWeek ),
Query1[Week], DESC
)
RETURN
CALCULATE ( SUM ( Query1[Sales] ), Last8Weeks )Unfortuantely, this returns same result as the 2nd image.
