Cumulative by week breaks at Week 10

[jhartranft60]

Hello,

I've created a measure to count enrollments week over week.  My data is sliced by week and by session (each session has 8-10 weeks, depending on time of year).  I'm using the following formula:

Cumulative_Enrollments = CALCULATE(SUM(Enrollments[Count], FILTER( ALLEXCEPT(Enrollments, Sessions[Session]), Enrollments[Week_Num]<=Max(Enrollments[Week_Num])))

*Note - There is a relationship built between Enrollments[Session] & Sessions[Session] that allows filtering by session across several charts/tables in the dashboard. That's why the ALLEXCEPT() function above references a different table than the rest of the formula.

This formula works absolutely perfect for any session I filter to that have 8 or 9 weeks, but if I filter to a 10-week session, the calculation begins with the Week 10 enrollment count.  I don't have any of the columns sorted in any way that 10 would come before 1, so I'm stumped.  I know I haven't provided much data, but hoping the answer may be simple.  If not, I will be happy to provide any sample data that may be needed.

Hi @jhartranft60,

In data table 'Enrollments', is [Week_Num] formatted as numeric (e.g 1, 2, 3, 4...10) or text (e.g Week1, Week2, Week3... Week10)? If it is a Text field, you need to add an extra column to sort the [Week_Num] column numerically rather than alphabetically.

Hello @v-yulgu-msft,

Thank you for replying.  Week_Num is formatted as a whole number.  The chart is using a column "Week Text" on the X-Axis and is sorted Ascending using the Week_Num column.
