AME for invoice Approval

 Hello,

We would like to use AME  a position/job hierarchy and a document type of invoice. We do not have a position/job hierarchy set up. We need this functionality for invoice approval.

Can you recommend a white paper or metalink document that explains how to do this? i have the Approvals Management implementation guide, but cannot see how to use position/job hierarchies with a document type of invoice.

Thank you,

Abigail
