Sourcing RFQ Approval Process?

Hi,

My idea is related to Oracle Sourcing RFQ Approval Process;

As Standard Functionality (standard WF);

The approval process is not hierarchical;

All approvers can access and approve the document simultaneously.

There are no dependencies among approvers

All members identified as approvers [approver check box marked Y] must approve the final version before the document can be published

For Business Requirements;

The approval process is should follow hierarchical flow

The list of approvers depend on multiple criteria such as [Amount, Type...etc.]

My Idea

My idea is to add a new process into standard WF (xyz) to call a new created AME Transaction Type (abc.)
