Supplier As Customer In Oracle EBS R12 Module.

Hello Experts -

I initially created ABC as a supplier, and it is now appearing under the customer form as Customer ABC. Kindly confirm if there are any additional mandatory steps required to ensure that ABC functions properly as both a supplier and a customer within the system.

Is it necessary to create a separate customer site and define Bill-To and Ship-To locations to ensure transactions are processed correctly?

Please guide in detail, thank U.
