percentage from the parent column, regardless what is the parent column as it changes

[KiMoZ]

I have date from 13 columns that user can change but they need the messure to caluclate the % from total an when they expand the expand be % of the parent not from the grand total tried the below and didnt work any ideas , 

% of Parent Total =
DIVIDE(
SUM(Table[MeasureColumn]),
CALCULATE(
SUM(Table[MeasureColumn]),
ALLSELECTED(Table)
)
)

This was impossible before Visual Calculations were introduced. Now it is trivial. read about COLLAPSE.
