Need to create AP Invoice from VBCS screen through OIC call

Summary:

Hi,

There is a requirement to create AP invoice from custom VBCS page. This page invokes OIC to create the AP invoice via Invoice Service from the Oracle ERP Cloud connection or via REST API through a REST connection. This connection is configured with a service user and hence the invoices created by this OIC always shows created by as this service user. We want the created by on the invoice to have the user id/username of the logged in user who submits the request from the VBCS page.

How can this be achieved?

Your help would be highly appreciated.
