consider this data
Label | Value |
A | 1 |
A | 2 |
B | 3 |
B | 4 |
C | 4 |
C | 5 |
and then compare this calculated columns
Column1 = CALCULATE(SUM('Table'[Value]),ALL('Table'), 'Table'[Label]='Table'[Label]) Column2 = CALCULATE( SUM('Table'[Value]), ALL('Table'), 'Table'[Label]=EARLIER('Table'[Label]) --we iterate over Table[Label] comparing it over the evalulation of the column in the filter context outside of CALCULATE ) Column3 = VAR CurrentLabel = 'Table'[Label] -- evaluated in the unmodified row specific context RETURN CALCULATE( SUM('Table'[Value]), ALL('Table'), --changes filter context to the whole table 'Table'[Label]= CurrentLabel )
you can use it to change the filter context of a column to one of its previous states

Can you please explain me with a real time example?
