Max( Set_Expression [ , Numeric_Expression ] )

A valid numeric expression that is typically a Multidimensional Expressions (MDX) expression of cell coordinates that return a number.

If a numeric expression is specified, the specified numeric expression is evaluated across the set and then returns the maximum value from that evaluation.
