New employee doesn't appear in the approver list when creating a rule

Hello,

We use AME with AP r12, with supervisor hierarchy (no position nor job)

I wanted to insert a new person into our hierarchy, so I created him as an employee and an user with this new employee attached.

Then I tried to create a substitution rule, but when I want to choose him in the list modifier 'Any approver', I didn't see him.

Should I run a program?

I see a similar issue in Metalink and a bounce of Apache solved it, but I don't want to go this way.

Please help!
