Use MROUND ( number, SIGN ( number ) * multiple ) if the the sign of the number is not known in advance:

DifferenceYOY RoundedToThousands := 
VAR Difference = [DifferenceYOY] 
VAR Multiple = 1000 
RETURN 
    MROUND ( Difference, SIGN ( Difference ) * multiple ) 
--  Rounding functions, using multiples of the second argument
--
--  FLOOR returns the smaller multiple
--  MROUND returns the nearer multiple (does not work with negative values)
--  CEILING returns the larger multiple
--  ISO.CEILING is like CEILING, handles differently negative numbers
