3782221 - I configure a cost center-based approval workflow in SAP Ariba Invoicing but PO-based invoices are automatically approved

• I configure an approval workflow variant in the Manage Workflows for Supplier Invoice Approval app using a cost center or WBS element as a start condition or step condition.
  
• When I post a supplier invoice that references a Purchase Order (PO), the invoice is automatically approved and does not trigger the workflow. 
  
• The Workflow tab on the invoice does not show any active approval step, and no approval task appears in My Inbox.
