Auto Approve POs that have been Matched & Received

Content

Hi. Using the Approval Workflow spreadsheet, does anyone know the criteria to have Invoices that are PO matched AND Received to auto approve. Currently we are saying:

if Invoice Header PO Matched = Yes

and if 

Invoice Line Receipt Matched = Yes

then 

Auto Approve

But it is not working as expected. Also need to do the inverse where:

if Invoice Header PO Matched = Yes

and if 

if Invoice Line Receipt Matched = No

then

Route to Project Manager or Requester depending if PO is Project-related or not

Not sure if the Invoice Line Receipt Matched is the way to accomplish the Receipt requirement. Any ideas to accomplish the Receipt requirement appreciated! Thank you.
