Trying to figure out the Purchase Requisition process

We have not used the purchase requisition process up to this point. I am trying to run sample information through a test 8.03.409C database. I setup a sample job with no material or operation lines. I then created a purchase requisition with 2 material lines for that job. Someone who messed around with purchase reqs a few years ago had created 2 requisition actions (Approve which is mandatory and Send to Purchasing which is checked as send to purchasing). I approved the Req and sent to purchasing. It now shows as Send to Purchasing-Pending. I then ran Generate Purchasing Suggestions as regenerative and using today's date. I thought that the lines would then show in PO Entry -> Actions -> New PO Suggestions but nothing shows up. What am I missing in this process?
