I have written a DAX which is supposed to mark a 1 in the cell if the Organisation has been with multiple (distinct) sectors, however, I keep running into some issues.
Dup =
CALCULATE(
COUNT('Inspection Scheduling Spreadsheet'[Licensed Establishment / Organisation]),
FILTER(
VALUES ('Inspection Scheduling Spreadsheet'[Licensed Establishment / Organisation] ),
DISTINCTCOUNT( 'Inspection Scheduling Spreadsheet'[Sector]) > 1
)
)
The column Dup should be returning 0 because the organisation has been with the same sector.

Whereas, this is when Dup should return a 1
So whenever an organisation has been with more than one sector the column Dup should return a 1 else 0
