# SAP RFC/BAPI and transactional CDC

> Resources, examples, configuration and evidence for SAP RFC/BAPI and transactional CDC.

Use the `@bijection/connectors/sap` entrypoint to declare SAP RFC/BAPI and transactional CDC resources.

## Availability

This page describes the pinned source package. Published availability is unestablished for this artifact. [Source build and package availability](https://docs.bijection.com/client/sdk-distribution.md).

## Resources and modes

| Resource | Mode | Description |
| - | - | - |
| RFC function | `rfc` | RFC/BAPI |
| SAP change stream | `cdc` | ABAP CDC |

Declare a resource in application code, then bind deployment-specific settings and credentials. See [typed resources](https://docs.bijection.com/integrations/resources.md), [connections](https://docs.bijection.com/integrations/connections.md) and [source inspection](https://docs.bijection.com/integrations/cli.md).

## RFC function

### rfc: RFC/BAPI

The following example matches configuration `standard`.

```ts theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
import { sap } from "@bijection/connectors/sap";
import { v } from "bijection/values";
import { makeFunctionReference } from "bijection/server";

export const writeDemo = sap.function.rfc({
  name: "BAPI_SALESORDER_CREATEFROMDAT2",
  digest: "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa",
  args: {
    import: v.object({ ORDER_HEADER_IN: v.object({ DOC_TYPE: v.string() }) }),
    changing: v.object({}),
    table: v.object({}),
  },
  output: v.object({
    export: v.object({ SALESDOCUMENT: v.string() }),
    changing: v.object({}),
    table: v.object({}),
  }),
  access: {
    read: makeFunctionReference<"query", any, [null]>("policies:sap"),
    reads: [],
  },
  governingRule: makeFunctionReference<"query", any, [null]>("policies:sap"),
});
```

> **Inferred record types**
>
> ```ts theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
> {
>   "key": string;
>   "contract_digest": string;
> }

The function references identify application policy queries. Implement those policies in your application; the references alone grant no authority.

#### Configuration: standard

Case: `sap/function/rfc/standard`.

Connection and resource configuration are declared by this exact case.

Credential kind: `http`. Keep credential material in the private credential inventory.

| Setting | Type | Required | Owner |
| - | - | - | - |
| `endpoint` | string | Yes | Shared connection |

Hosted qualification: **unestablished for this catalog configuration**. Installed connections report their own identity, authority and current status.

## SAP change stream

### cdc: ABAP CDC

The following example matches configuration `standard`.

```ts theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
import { sap } from "@bijection/connectors/sap";
import { v } from "bijection/values";
import { makeFunctionReference } from "bijection/server";

export const demoRows = sap.stream.cdc({
  name: "ORDERS",
  digest: "bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb",
  row: {
    MANDT: v.string(),
    VBELN: v.string(),
    NETWR: v.string(),
    WAERK: v.string(),
  },
  access: {
    read: makeFunctionReference<"query", any, [null]>("policies:sap"),
    reads: [],
  },
});
```

The function references identify application policy queries. Implement those policies in your application; the references alone grant no authority.

#### Configuration: standard

Case: `sap/stream/cdc/standard`.

Connection and resource configuration are declared by this exact case.

Credential kind: `http`. Keep credential material in the private credential inventory.

| Setting | Type | Required | Owner |

| `endpoint` | string | Yes | Shared connection |

**Recorded checks**

| Requirement | Scope | Evidence | Result |
| - | - | - | - |
| change-history-gap | \{"kind":"collection","name":"records"} | The ABAP add-on owns seeded history, update-LUW events and epoch refusal. ABAP activation and hosted CDC recovery require a real SAP system. | Execution result unavailable |

Hosted qualification: **unestablished for this catalog configuration**. Installed connections report their own identity, authority and current status.

## Provider guidance

Use `bijection source sap capture` to capture selected JCo function interfaces and
seeded ABAP CDC stream schemas. A `sap.contract` project generates typed bindings
under `_generated/sap`. Private gateway endpoint, bearer credentials and CDC epoch
belong to the normal HTTP connection binding.

Function resources use exact captured signatures, explicit governing rules and
single-attempt delivery. The customer gateway uses SAP JCo and keeps a BAPI and
its explicit commit/rollback on one stateful session. RETURN selectors and BAPI
mode are operator declarations. A lost reply remains unknown; no resend, durable
SAP receipt or changed business state is inferred.

CDC resources require the versioned Bijection ABAP add-on, complete committed seed
and customer-installed business update hooks. The stream retains full after-images
and deletions from sequence zero. Update-task failure rolls back its log records
and sequence. Schema drift, a changed epoch or missing history refuses progress.
The source does not claim atomic publication of an entire multi-row SAP transaction.

The gateway and installable ABAP source live with Bijection's SAP integration.
SAP JCo binaries are supplied by the customer, and are not redistributed. These
bindings neither install SAP objects nor establish live SAP qualification.
