Where in the UI can we see who is the Purchase Order Creator or Owner?

Hello Community,

I've seen that requisitions always show who the requestor is, there is a "Requestor" field, also there are so many references to requisition owner or creator.

In the purchase order we can see the "Buyer" field, but this is not actually who could have created the PO. Is there any field in the UI where we can detect who created the PO?

I've searched in Oracle documents and can't find this answer.

Thank you in advance for your help.
