Hi guys,
I have a scenario where anyone in the company can create PR for a project. PR should always first go to Project Manager for review (easy already configured) once project manager review and give a go a head that this PR can be consumed on my project it should than go to approval process.
If the PR is within Project Manager approval limit (signing authority) it should get automatic approved. if its not with in PM approval limit than PR should be routed to PM's manager not requester or preparer manager.
If PM raise a PR for his own project, it should again goes to himself for review (unusual i know) and then irrespective to approval limit and purchase requisition approval amount, it should go to him/her manager for approval.
If PR is raise by PMs manager for PM project., it should again goes to himself for review (unusual i know) and then goes to manager's manager for approval.
I have configured following.
- signing limits
- position hierarchy / managerial hierarchy
- review workflow element selected participants and role based select expenditure participant so PR should go to PM for review first.
My problem is that PR managerial hierarchy does not start from PM its starts from following.

Can some advice me how can I configure this business scenario without customization.
Please preparer will not select requester as PM. preparer infarct never use requester field.
