Hi Carolina, great question. If you’re referring to SAP S/4HANA Cloud, private edition (often confused with “HANA cloud”), the recommended way to automate Material Master is to use the released OData APIs for the Product (Material) object. In S/4HANA the Material Master is modeled as “Product Master,” which you can also maintain via the “Manage Product Master” app; this is the same business object you would target with the APIs .

Recommended options (from most to least cloud-friendly):

• OData V2 Product Master API (commonly known as API for Product Master). This is the standard for create/read/update of products and their plant/sales/valuation views in S/4HANA and is fully supported in Private Edition. S/4HANA PCE broadly exposes business objects via OData APIs (example shown for ATP to illustrate the pattern in PCE) .
• BAPI/RFC (BAPI_MATERIAL_SAVEDATA) if you’re inside ABAP or must integrate via RFC in a PCE/on-prem style scenario. It’s still widely used, but prefer OData for new integrations.
• IDoc MATMAS for distribution scenarios to other systems. It’s robust for asynchronous/mass flows, but for CRUD automation from external apps, OData is typically simpler.

Key considerations before you pick the API:

• Long material number (40 chars): if you’ve enabled it, ensure your external interfaces and payloads use the extended fields; SAP’s guidance is to use the “new/extended” fields in released external interfaces when long material is active .
• Scope: do you need to create base data only, or also extend to plant/sales/WM/EWM views? The Product Master API covers sub-entities; for warehouse-specific data you still maintain via the Product Master/EWM apps and related objects .

To point you to the exact service name and entities, could you share a bit more detail?

• Edition/version (e.g., S/4HANA Cloud, private edition 2023/2024)?
• Operations: create, change, extend to plant/sales, classification/batches, or mass loads?
• Integration style: real-time from an external app, or scheduled/batch via middleware?

With that, I can suggest the precise service name, example payloads, and the right entity sets for your case. Happy to help you wire it up end-to-end.
