Employee as Supplier

Hi,

The following question pertains to Rel12, Payables, HR is only Shared.

When automatically creating employees as supplier, supplier number is defaulted to employee number.  Can someone please confirm this is out of the box functionality?

I have two internal clients with two separate and distinct Oracle Rel 115.10 applications instances.  Each instance assigns supplier number differently for employee types: one defaults to employee number from employee form, the other assigns the next sequential supplier number to employee types.  I can't tell which process has been customized.  We need to confirm the out of the box functionality as we are now planning for a fresh Rel 12 re-implementation.  Appreciate a quick response.  Thanks in advance.
