I'm Using Checklists in Oracle HRMS R12.
When I am trying to create a life event reason(Total compensation-->general definitions-->additional setup)
I'm not able to select the Person Changes and Related Person Changes tabs as they are being shown as disabled.
Some one advice me on why those two tabs are disabled?
I can see the life event reasons which means OAB is installed, I guess
Oracle Advanced Benefits (OAB) must be installed in order to create a Life Event with Defined Person Changes. So a full install of OAB is a mandatory prerequisite to using Life Event Checklists.
So Please check, and Install Oracle Advanced Benefits (OAB) in order to set up life events.
This will resolve your issue.
Yes, this is the cause. OAB must be installed, but not necessarily implemented nor licensed to use it. Please refer to the Oracle support note "OAB\OSB Licensed to Use the Life Event Checklist Functionality? [ID 748543.1]". You can test this in a test/Dev environment first then proceed.
