Hello Experts,

We'd like to allow our end users that can submit requisitions to request also new supplier via the actions, More tasks drop down at the Requisition home page. The issue is that when opening the Request new supplier page it is missing the default procurement BU.

I've tried grant the employee role, added the default BU at the Procurement BU profile but with no success

With my user I can submit it but I have additional roles as supplier admin, buyer and other implementation roles.
