RE: Calculate max value of a column
 
You need to feed your ports through an Aggregator Tranformation.  eg.

Input  = salary.  Not output
Output = maximum_salary --> max(salary) - Output

Connect the maximum_salary fields to the output to use it
Define other keys as "Group by" as needed.

You cannot use max(salary) function in expression - it only works on a single row
