I have two tables, Courses and Lessons. A course can have muliple lessons. A lesson can be in many courses. Because of this, I have a lookup table (~Lookup_Couse-Lessons) with a 1:Many relationship on each side. I need a measure for a visual that will calculate the total Course Duration by summing the Duration in Hours for each Lesson within a course.
I'm new to DAX, and confused. I've spent a few days on this, playing with SUMX, FILTER, CALCULATE, and more. I'm pulling my hair out, and would really appreciate any help!
Solved! Go to Solution.
Hi, @Anonymous , I assume you use a matrix with Courses[Course] in row field, you may try such a measure to sum up durations of lessons composed in corresponding courses.
Sum Duration =
CALCULATE ( SUM ( Lessons[Duration in Hours] ), '~Lookup_Couse-Lessons' )
Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension! |
DAX is simple, but NOT EASY! |
