3769592 - ProductHierarchyInternalID and ReceiverProductHierarchyInternalID not populated in SOAP API for Product Master

ProductHierarchyInternalID and ReceiverProductHierarchyInternalID are expected per the Node Product documentation, but not populated in the replicated SOAP message for product when replicating Product Master data from SAP S/4HANA Public Cloud to Client.

The queries focus on:

1. Whether a known limitation about Product Hierarchy visibility mentioned in KBA 3695474 also applies to the SOAP API
2. Why ProductHierarchyInternalID and ReceiverProductHierarchyInternalID remain in the API specification if so. 

SAP S/4HANA Cloud Public Edition

This is intentional behavior of SAP S/4HANA Public Cloud system, not a defect. This behavior is also applied for the SOAP API Product Master - Replicate from Client to SAP S/4HANA Cloud.

• In On-Premise systems, Product Hierarchy was stored directly in the material master (table T179, field MARA-PRDHA).
• In S/4HANA Cloud Public Edition, this has fundamentally changed: Product Hierarchy is no longer part of the product record. It is now managed centrally via the Fiori app "Manage Product Hierarchies", based on a new UHF framework that enables version control, validity periods, unique product assignments per hierarchy version, and multi-tenant compliance.

Because the hierarchy data is decoupled from the product master, the SOAP API returns empty values for the corresponding fields by design. The API itself remains Active in the Business Accelerator Hub with no planned deprecation — it has simply evolved to reflect this new architecture.

Use specific, separate ODATA APIs designed for product hierarchies and assignments to access product hierarchy information for a product:

• Product Hierarchy Nodes – Read, Create | SAP Help Portal
• Products to Product Hierarchies Assignment - Read, Create | SAP Help Portal

The relevant APIs in Business Accelerator Hub:

• Product Hierarchy Nodes – Read, Create
• Products to Product Hierarchies Assignment - Read, Create

This behavior of Product Hierarchy Field is also explained in the following KBA:
