3578123 - Issue with Updating Contact's Email Address via API_BUSINESS_PARTNER in SAP S/4HANA Cloud Public Edition

When attempting to update a contact's email address via A_AddressEmailAddress using API_BUSINESS_PARTNER, the API processes the updates successfully. However, the updated email address does not appear in the Manage Business Partner Master Data or Maintain Business Partner apps.

SAP S/4HANA Cloud Public Edition

Use the A_AddressEmailAddress API to update a Contact's email address.

1. Go to Maintain Business Partner app.
2. Open the Business Partner.
3. Navigate to the relationships tab.
4. Select the contact person.
5. Go to the address data tab.
6. The contact person's email ID remains unchanged.

Although the PATCH operation allows the update, it is not reflected in the fiori apps (Manage Business Partner Master Data or Maintain Business Partner). This is because the Business Partner framework currently does not support maintenance for contact person addresses. While the system appears to process the update, performing this operation is not recommended, as it may lead to inconsistencies.

SAP is actively working on developing this functionality and aims to release support for this use case at the earliest possible time.
