What authentication does SAP S/4HANA require?

SAP S/4HANA uses Communication Arrangements with a dedicated Communication User. You create a technical user in the Fiori Launchpad, assign it to a Communication System, and link it to the appropriate Communication Scenario (e.g. SAP_COM_0008 for Business Partners).

Can I create purchase orders through the agent?

Yes. The `create_purchase_order` tool posts to the A_PurchaseOrder OData endpoint. Provide the supplier, purchasing organization, plant, material, quantity, and price — the agent returns the PO number on success.

Does it support querying custom OData services?

Absolutely. The `query_odata` tool executes GET requests against any OData v4 service exposed via your Communication Arrangement, including custom CDS views. Full $filter, $expand, and $select support is included.

Can I check stock levels across multiple plants?

Yes. The `get_material_stock` tool queries the A_MaterialStock OData service, returning current stock quantities by plant and storage location. You can filter by material number, plant, or storage location.
