Divide count distinct column by non calculated column

oriabbhou1 — Sat, 23 Jan 2021 06:45:13 GMT

Hi,

I'm doing a quick measure to divide 2 columns without doing any calculation on the denominator column.

So here's the scenario: The numerator column(lesson count) does a count of lessons and i have a criteria for each school. I entered the criteria(required lesson) by creating a table in powerbi and joining by school in the relationships tab. The issue is that when i try to divide lesson count(i did a count distinct on this column which is what i wanted) by required lesson, it forces me want to use some form of aggregation(sum, count, standard deviation, etc) to the required lesson column which is not want i want. I just want to divide lesson count/required lesson without the aggregation to the denominator. Is there a dax that does this perfectly? I've looked at some post but the answers i see is not working for me.

Please help.

Hey oriabbhou1

I'd Suggest you to create a Calculated column for your solution

column=divide(table[LessonCount],table[RequiredLesson],0)

if you dont want to use above solution can you please share some sample data

Did I answer your question? If Yes, Please mark this as a solution

Hi iXpert_info & Anonymous ,

I tried creating a calulated column but the required lessons column from the lessons required table is not popping up as the denominator.

Both columns are whole numbers so i dont see why it shouldnt work. I'm pretty much trying to accomplish the % completion colum in the sample data below.

Here's my sample data below:

oriabbhou1 try the following

% Completion = DIVIDE('Lessons(SQL Table)'[Count of Lesson],RELATED('Lesson Required Table'[Lesson Required]))

I've added a PBIX file to this one drive link that shows how I achieved it for you.
