Personalizing the PERWSHRG form by making the supervisor field mandatory

Question

Hello
I need to make the Supervisor field on the Assignment screen of the PERWSHRG form mandatory. There are many employees in our oracle system without a supervisor. I need to force the user to capture a supervisor whenever an employee is queried without a supervisor.
When an employee is queried i can make the supervisor field manadatory (yellow) on the assignment screen. But somehow oracle still alllows the user to save and then exit the record without having to enter a supervisor. Almost like the madantory field is not enforced
my current setup is
Condition:
Trigger Event: WHEN-NEW-ITEM-INSTANCE
Trigger object: PERSON.LAST_NAME
Condition: :PERSON.LAST_NAME is not null and
:ASSGT.SUPERVISOR_ NAME is null
Processing Mode: Both
Actions:
Seq:1
Type: Property
Object Type: item
Target Object: ASSGT.SUPERVISOR_NAME
Property Name: REQUIRED (APPLICATIONS COVER) --and i even tried REQUIRED and REQUIRED (ITEM-INSTANCE)                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   

Answer 1

Hi,
At the time of personalizing the assignment form it may not work perporly as you expected because the record is created as soon as the employee record is saved on the enter and matain form. That's you are facing problem and try to do it in other way around.
1) when validate record.
2) Call a function or procedure to show error message if the user do not pass any value.
and the last option is try to built a USER HOOK to validate the same.
Thanks
