PO Approval Customization

Hello Gurus,

We have a custom requirement. We want to customize the standard PO Approval Workflow to meet the following need:

We have 2 business groups. The first (BG1) is used for HR jobs and positions assignments to employees, and the second one (BG2 : a fictive business group) is just used to define PO approval hierarchies and approval groups.

We would like to customize the approval workflow, so that it uses the BG2 business group to retrieve the approval hierarchies instead of BG1.

The second BG (BG2) is a fictive business group, it is just used to define approval hierarchies and groups.
