PO report by OR originator

Hi Everyone,

We are looking for a way to generate a PO report by OR originator.

Our process is that user A will create an OR using P4310 that will then get approved. Once approved, user B will use P43060 to turn the OR into an OP.

We are looking for a simple way to track the original originator for each purchase order, not the one who just turned the OR into a PO.

Is there either:

1- A PO report that will show related OR and related originator

2- A way to keep user A name as originator in OP instead of user B when generating PO  with P43060?
