{/* MANUAL-CONTENT-START:intro */}
[SAP S4HANA](https://www.sap.com/products/erp/s4hana.html) is SAP's flagship intelligent ERP suite, running on the in-memory HANA database. It powers finance, supply chain, procurement, sales, and manufacturing for organizations of every size, and exposes its business data through a broad catalog of OData services on SAP Business Technology Platform (BTP).

With SAP S4HANA, you can:

- **Run core business processes**: Manage finance, procurement, sales, logistics, inventory, and manufacturing on a single source of truth.
- **Model master data at scale**: Maintain business partners, customers, suppliers, products, and organizational structures across multiple company codes, sales organizations, and plants.
- **Execute transactional flows end to end**: Create and update sales orders, purchase requisitions, purchase orders, deliveries, billing documents, supplier invoices, and stock movements with full audit trails.
- **Govern access cleanly**: Use Communication Arrangements, Communication Systems, and Communication Scopes to scope OAuth client credentials to exactly the services each integration needs.
- **Integrate via standard OData**: Every entity supported here speaks OData v2 with consistent paging, filtering, expansion, and ETag-based optimistic concurrency.

In Sim, the SAP S4HANA integration lets your agents read and write directly against your tenant's OData services using per-tenant OAuth 2.0 client credentials. Agents can list and fetch master data, create and update transactional documents, run stock and material document queries, and execute arbitrary OData v2 calls against any whitelisted Communication Scenario — all routed through a single internal proxy that handles token acquisition, CSRF fetch-and-retry, and OData error normalization. Use it to automate order-to-cash, procure-to-pay, and inventory workflows, keep SAP in sync with the rest of your stack, or trigger downstream agent logic from SAP business events.

## Usage Instructions

{/* MANUAL-CONTENT-START:usage */}
Connect any SAP S4HANA tenant — **Cloud Public Edition**, **Cloud Private Edition (RISE)**, or **on-premise** — and read or write business data through the official OData v2 services. Each tool routes through a single internal proxy that handles token acquisition, CSRF fetch-and-retry for write operations, and OData error normalization.

### Deployment modes

Pick the deployment that matches your tenant in the **Deployment** dropdown:

- **S4HANA Cloud Public Edition** — provide your **BTP subaccount subdomain** and **region** (e.g., `eu10`, `us10`). The host is derived automatically as `{subdomain}-api.s4hana.ondemand.com`, and OAuth tokens are fetched from the matching BTP UAA endpoint. Authentication is OAuth 2.0 client credentials configured in a Communication Arrangement.
- **S4HANA Cloud Private Edition (RISE)** — provide your **OData Base URL** (e.g., `https://my-tenant.s4hana.cloud.sap`). Authenticate with **OAuth 2.0 client credentials** (provide the tenant's UAA `tokenUrl`, `clientId`, `clientSecret`) or **HTTP Basic** with a Communication User (`username`, `password`).
- **On-premise S4HANA** — provide your **OData Base URL** (e.g., `https://sap.internal.company.com:44300`). Authenticate with **OAuth 2.0 client credentials** issued by your on-prem identity provider, or **HTTP Basic** with a service user.

### What you can do

Read and create business partners, customers, suppliers, sales orders, deliveries (inbound/outbound), billing documents, products, stock and material documents, purchase requisitions, purchase orders, and supplier invoices. Update business partners, customers, suppliers, products, sales orders, purchase orders, and purchase requisitions with PATCH. Run arbitrary OData v2 queries against any whitelisted Communication Scenario or registered service.

### Optimistic concurrency

All update tools accept an optional `ifMatch` ETag. When omitted, `If-Match` defaults to a wildcard (unconditional). For safe concurrent updates, fetch the entity first, capture its ETag from the response, and pass it as `ifMatch` to detect lost updates.
{/* MANUAL-CONTENT-END */}


Connect SAP S4HANA Cloud Public Edition with per-tenant OAuth 2.0 client credentials configured in your Communication Arrangements. Read and create business partners, customers, suppliers, sales orders, deliveries (inbound/outbound), billing documents, products, stock and material documents, purchase requisitions, purchase orders, and supplier invoices, or run arbitrary OData v2 queries against any whitelisted Communication Scenario.

### `sap_s4hana_update_product`

Update fields on an A_Product entity in SAP S/4HANA Cloud (API_PRODUCT_SRV). Uses HTTP MERGE (OData v2 partial update) — only the fields you provide are written; existing values are preserved. Flat scalar header fields only — deep/multi-entity updates across navigation properties are not supported by API_PRODUCT_SRV MERGE/PUT (see SAP KBA 2833338); update child entities (plant, valuation, sales data, etc.) via their own endpoints. If-Match defaults to a wildcard (unconditional) — for safe concurrent updates pass the ETag from a prior GET.

### `sap_s4hana_update_purchase_order`

Update fields on an A_PurchaseOrder header in SAP S/4HANA Cloud (API_PURCHASEORDER_PROCESS_SRV). Uses HTTP MERGE (OData v2 partial update) — only the fields you provide are written; existing values are preserved. Header-only — line-item changes are not supported via deep update on the header (SAP KBA 2833338); use the A_PurchaseOrderItem entity directly to modify items. If-Match defaults to a wildcard - for safe concurrent updates pass the ETag from a prior GET to avoid lost updates.
