Summing value from a matrix

Hi Anonymous , Thank you for reaching out to the Microsoft Community Forum.

Build a new measure that recreates that row-level context manually using SUMMARIZE, and then sums the results with SUMX. Example:

TotalReallocateClasses =
VAR vTable =
SUMMARIZE(
Sheet1,
Sheet1[acad_org],
Sheet1[day_of_week],
"__Reallocation", [ReallocateClassesPerDay]
)
RETURN
SUMX(vTable, [__Reallocation])

This forces DAX to recalculate [ReallocateClassesPerDay] for every (acad_org, day_of_week) pair exactly as it appears in the matrix and then adds them up to give the true total. After writing this measure, drop it into a card visual to display the correct total number of classes that need to be reallocated.
