Impact of Changing Primary Address at Customer Party Header Level

Summary:

We have a customer with two different business unit sites (ABC and DBD), each having its own primary address.

The customer is asking how changing the primary address at the customer party header/registry level will impact the system, particularly in cases where the primary address for both the sites are different and one of the site address becomes the primary at registry.We understand that for AR invoices and OM orders, the system picks the address associated with the business unit's site. However, the customer is concerned that changing the primary address at the header level might have an impact on one of the business unit whose primary address not being setup as primary at registry level.
