Best Practices for Managing "From Email Address" in Cross-Region Customer Accounts

Hi Experts-

We are encountering a challenge with how collector email addresses are handled in Oracle AR when customer accounts are shared across multiple Organizational Units (OUs) or regions.

Currently, Oracle's invoice generation programs (e.g., Invoice Print New Invoices, Contract Invoice Print New) use the collector details at the account level to determine the "From Email Address" for invoices. This setup creates issues when:

1. A single customer account spans multiple OUs or regions, resulting in invoices being sent with an email address tied to one region (e.g., APAC) instead of the region that generated the invoice (e.g., EMEA).
