Hello @mjmcs13,
Thank You for posting your query onto the Forum.
Well, in this case, I’m presuming that when you say “ALL” option is not working you mean that eventhough when you make a selection in the slicer for Schools, the percentages should not change upon those selections.
Below is the measure alongwith the screenshot of the final results provided for the reference -
SB Math Average - Harsh =
CALCULATE(
CALCULATE(
AVERAGEX( Assessments ,
Assessments[Performance_Score] ) ,
FILTER( Assessments ,
Assessments[TEST_SHORTNAME] = "SB" &&
Assessments[SUBLEVEL1_SHORTNAME] = "MATH" ) ) ,
ALL( School_LKP ) )
I’m also attaching the working of the PBIX file as well as providing few of the links below of the posts which our expert @AntrikshSharma has created.
Hoping you find this useful and meets your requirements that you’ve been looking for.
Thanks and Warm Regards,
Harsh
