How do you know if probation end date is using auto complete?

Our Probation End Date is populating upon entry of the method and a begin date. We would like to understand what is there and how to change it.

• How do you confirm that an auto complete rule is controlling that task?
• If it isn't auto complete, where do you look so you can change that?
• If it is auto complete, is the only way to get permission to address it via a key and enabling the auto-complete rules in the Manage Profile Options task? Wouldn't that be done if an auto complete rule was in place?

Thanks,

Wendy
