Document Approval job level workflow

Content (required):

Hi all

To Document Approval I want to use Job Level as the list builder. On all PO´s it is required to enter project information as well.

Just a simple example - the hierarchy looks as follow:

Director = Level 4 with an approval limit of 10,000,000.

Vice President = Level 3 with an approval limit of 5,000,000.

Administrative Officer = Level 2 with an approval limit of 1,000,000

Project Managers (Role-based, not job) must approve all PO´s at first and can approve up to 100,000 without anyone else's approval.

What will happen with the approval for a PO of 500,000 if the Director is also the Project Manager?
