In E1 9.2 requisition self service, how can we approve by document type?

Hello MOSC,

In E1 9.2 requisition self service, how can we approve a requisition by requisition document type?

I know that we can create multiple versions of business function P43E0001 and give them multiple document types. Also different business units could use different document types, but what is the next step?

We currently have an approval route (distribution list) for each employee. The approval authority constants does not have a level for "employee/business unit".

Thanks in advance for any suggestions on approval by requisition document type.

Russell
