Use aggregator stage. Put the group by column as department_no and count column as employee_name.
Propagate count column as employee_list which will gives the number of employs based on department_no.

First sort the columns Department_no and employee_name in ascending order.
Then use the stage variables.
current=department_no
result= If current=prev then result:,:employee_name else employee_name
prev=current
Then use Remove duplicate stage to retain last.
Finally populate the result to target you will get the required output.

Use Pivot enterprise stage and select vertical pivoting. Also perform sort in the stage using the partitioning as Hash. Take Dept_number as group by column and Employee_name as Pivot column and the output will be in the form of Dept_number|Employee list. For example:
10|A|B|C|D
20|P|Q|R|S
