Need help/suggestions

Question

hi ,
i need to develop a report --
a report with columns: emp_id, emp_name, manager_number
Basically i have 4 tables -- dept_table, emp_table, time_table, role_table
dept_table has columns ---> dept_id, dept_name
emp_table has columns --> emp_name, dept_number, emp_key, emp_id
time_table ---> time_key, year
role_table --> time_key, emp_key
joins:
emp_table and role_table are joined thru ---- emp_key
role_table and time_table are joined thru ------ time_key
dept_table.dept_id = emp_table.dept_number
parameter of the report:
year from time_table.
for example
the dept_table has 20 depts => 20 dept ids
the emp_table has 100 employees.
these 100 employees wud be assigned to one of the 20 depts. (some employees might be given a wrong dept id which actually doesn’t exist)
Now i need to develop a report with the field columns of the emp_table: emp_id, emp_name, dept_number
where dept_number is not a valid dept_number (i.e. dept_id not present in dept_table)
how shud i proceed?
In discoverer admin, how shud i create the join between the database folders dept_table and emp_table like
master_item detail_item
dept_table.dept_id = emp_table.dept_number (???)
or the other way round???
under options of create join: what shud be the join details which i need to select ??
thanks

Hi Rodwest,
Thanks for the suggestion. But did not work.
(i) For all the employees that are not assigned to a department.
I have created the join and the report as u suggested. I have put 4 fields from emp_table and 1 field (i.e. dept_table.dept_id).
There I could see the employees who are not assigned to any dept has dept_table.dept_id as NULL. So, when I apply the condition dept_table.dept_id IS NULL to pick up all employees without a valid department, it still shows some employees with valid depts.
i dont understand what to do.
(ii) I have proceeded just as u suggested. But I dont see all the depts. some depts are filtered by the parameters (this is the main issue).
I need to have all the depts. and its corresponding employee count irrespective of the parameters.
Some depts are filtered by the parameters. the dept_table doesnt have any of the parameters. There are three parameters, one from time_table and 2 from emp_table. These 3 parameters are filtering the dept_id s and is not allowing all the depts to show up.
awaiting ur response.
Thanks
