PO Owner
The PO Owner role can be used to designate who is responsible for the PO. It does not give access to PO list page, reports, etc. Note this role is not assigned; it is obtained when the user is assigned as a PO Owner on a PO. If the user is removed from all POs as the PO Owner, then the role will be removed from that user and from any alternates for that user.
PO Owner must be an active user. If the PO is associated with a PR, the field is pre-populated with the value from the Requestor field of the original PR, or the latest PR Mod if it exists.
For Mods, it is pre-populated with the value from the original PO.
If the PO Owner is modified on a document, the PO Owner of all the other documents of the series does not change. In other words, the historical data is not automatically modified by the system.
