Visual has exceeded available resources - how to optimize dax code?
Hi there,
I think my DAX code is slowing down my visual, it will not load because the code is taking too long to run for each column of my table visual. How can i optimize my code or make it more efficient?
I am creating a visual where each column shows training completion date for a course, for each employee. My dax code is broken down in two measures : 1st is to check if course is complete, 2nd is to retrieve the completion date. 2nd is the one that i show on my dashboard. The course transcript is the one i use to check completion. It is in a one - to -many relationship with my main list of employees who each have unique ID. The transcript has many courses so one employee can complete many courses.

Hi ALL,
Firstly MFelix and johnt75 thank you for yours solutions!
And himanimistry , For your first code, you can combine the FILTER condition into a single FILTER function, which can be used to reduce the number of iterations, and you can leave out the RELATEDTABLE if the table relationships are already defined in the model. reduce the complexity of the code, as MFelix and johnt75 wrote
If the amount of data is too large, using maxx will increase the computation time unnecessarily, you can try the combination of caculate and max to optimize the code.FON304 Date(optimize) = CALCULATE( MAX(CSPS_TRANSCRIPT[Transcript Completion Date]), CSPS_TRANSCRIPT[NextGen Course Code] = "FON304" && CSPS_TRANSCRIPT[Transcript Status] = "Completed Successfully" )If you have further questions, check out the pbix file I uploaded, I hope it helps, and I'd be honored if I could help you out!
Hope it helps!

You can try
FON304 = IF ( CALCULATE ( COUNTROWS ( CSPS_TRANSCRIPT ), CSPS_TRANSCRIPT[ NextGen Course Code] = "FON304", CSPS_TRANSCRIPT[Transcript Status] = "Completed Successfully" ), "✔" ) FON304 Date = VAR CompletedCourses = FILTER ( VALUES ( CSPS_TRANSCRIPT[Course ID] ), [FON304] = "✔" ) VAR Result = CALCULATE ( MAX ( CSPS_TRANSCRIPT[Transcript Completion Date] ), CompletedCourses ) RETURN ResultHi himanimistry ,
Try to use the following code then you can force the condittional formatting to change the 1 into the icon that you need
FON304 = IF( COUNTROWS( FILTER( CSPS_TRANSCRIPT, CSPS_TRANSCRIPT[ NextGen Course Code] = "FON304" && CSPS_TRANSCRIPT[Transcript Status] = "Completed Successfully") > 0 , 1 )FON304 Date = MAXX(ADDCOLUMNS(CSPS_TRANSCRIPT, "FON304", [FON304]), [FON304] = 1))Hi ALL,
