Load SAP BW Open Hub Application Server data to Microsoft Fabric

SAP BW Open Hub is a service designed for distributing data from an SAP Business Warehouse system to non-SAP downstream systems and data marts. Everything needed to build a working SAP BW Open Hub Application Server → Microsoft Fabric pipeline is on this page: the API's base URL, authentication, endpoints, pagination and incremental field — plus a prompt that hands the whole job to your coding agent.

Build your SAP BW Open Hub Application Server to Microsoft Fabric pipeline

Paste this prompt into Claude, Codex, or Cursor. The agent does the rest.

That scaffolds a dltHub workspace and installs the dltHub AI harness — the project rules, the secrets-management skill, and the dlt MCP server your agent needs to work safely. From there it reads the SAP BW Open Hub Application Server API, proposes the endpoints to load, then writes, runs and validates the pipeline while you review rather than type. Credentials are inspected through MCP tools, so your agent never reads secrets.toml itself. How the LLM-native workflow works →

Prefer to write it yourself? Every fact the agent uses is below.

SAP BW Open Hub Application Server API at a glance

These values come from the SAP BW Open Hub Application Server API documentation. Check them against the vendor's current reference before relying on them in production.

---

How do I authenticate with the SAP BW Open Hub Application Server API?

The SAP BW Open Hub service utilizes ABAP-based function modules (e.g., RSB_API_OHS_DEST_GETLIST) rather than a REST API; external connectivity to the Open Hub service is typically established via RFC (Remote Function Call) or dedicated OData services provided through SAP Gateway Foundation.

1. Get your credentials

To obtain credentials for an SAP BW Open Hub integration, create a dedicated SAP user account using transaction code SU01. Assign this user the appropriate authorization role (e.g., /GOOG/BWOH_CDF_AUTH or a custom role containing the necessary RFC and SAP BW execution permissions). The recommended user type is a Communication user (Type C) for basic authentication or a System user (Type B) for OAuth 2.0. Ensure the user has permissions for authorization objects such as S_SDSAUTH.

2. Add them to .dlt/secrets.toml

Copy
[sources.sap_bw_open_hub_application_server_source]
sap_bw_username = "your_sap_username"
sap_bw_password = "your_sap_password"
sap_client = "800"
sap_host = "your_sap_app_server_host"
sap_system_number = "00"

dlt reads this file automatically at runtime. With the harness, the setup-secrets skill prompts you for the values and never handles the raw credential in chat. For production, see setting up credentials with dlt.

What SAP BW Open Hub Application Server data can I load into Microsoft Fabric?

These are the SAP BW Open Hub Application Server endpoints dlt can load into Microsoft Fabric:

---

How do I load only new SAP BW Open Hub Application Server records?

The SAP BW Open Hub Application Server API reference does not document a timestamp or sequence field for these endpoints, so there is nothing to advertise here as verified. Pick a field from the endpoints table above that increases with every write, then set it as the cursor_path.

Copy
{"name": "open_hub_destinations", "endpoint": {
    "path": "sap/opu/odata/sap/ODP_BW_SRV/OpenHubDestinations",
    # Replace with a field that increases on every write.
    "incremental": {"cursor_path": "REPLACE_ME", "initial_value": "2024-01-01T00:00:00Z"},
}}

On the first run dlt loads everything from initial_value; on every run after that it requests only what changed and appends with write_disposition="merge" if you set a primary key. See incremental loading.

What does the generated SAP BW Open Hub Application Server pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading RSB_API_OHS_DEST_READ_DATA and RSB_API_OHS_DEST_GETLIST from the SAP BW Open Hub Application Server API into Microsoft Fabric:

Copy
import dlt
from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources

@dlt.source
def sap_bw_open_hub_application_server_source(credentials=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "N/A (The Open Hub service does not expose a standard public REST API; connectivity is provided via SAP Gateway OData services or RFC).",
            "auth": {"type": "http_basic", "username": "REPLACE_ME", "password": credentials},
        },
        "resources": [
            {"name": "open_hub_destinations", "endpoint": {"path": "sap/opu/odata/sap/ODP_BW_SRV/OpenHubDestinations", "data_selector": "d.results"}},
            {"name": "open_hub_data_delta", "endpoint": {"path": "sap/opu/odata/sap/ODP_BW_SRV/DeltaLinksOf{id}('{token}')/ChangesAfter", "data_selector": "d.results"}}
        ],
    }
    yield from rest_api_resources(config)


def load_sap_bw_open_hub_application_server_to_fabric() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="sap_bw_open_hub_application_server_pipeline",
        destination="fabric",
        dataset_name="sap_bw_open_hub_application_server_data",
    )
    load_info = pipeline.run(sap_bw_open_hub_application_server_source())
    print(load_info)


if __name__ == "__main__":
    load_sap_bw_open_hub_application_server_to_fabric()

Run it with python sap_bw_open_hub_application_server_pipeline.py. The agent iterates on this until it loads cleanly — you review and approve, rather than write it from scratch.

How do I query SAP BW Open Hub Application Server data in Microsoft Fabric?

dlt creates one table per resource. Query the loaded data with Python or SQL — or ask your agent to, through the MCP server's execute_sql_query tool.

Python (pandas DataFrame):

Copy
import dlt

data = dlt.pipeline("sap_bw_open_hub_application_server_pipeline").dataset()
df = data.open_hub_destinations.df()
print(df.head())

SQL:

Copy
SELECT * FROM sap_bw_open_hub_application_server_data.open_hub_destinations LIMIT 10;

See querying your data with dataset and exploring it in marimo notebooks.

How do I deploy the SAP BW Open Hub Application Server to Microsoft Fabric pipeline in production?

The pipeline runs locally, which is ideal for prototyping and one-off analysis. When you need it on a schedule, monitored on every load, and shared with your team, deploy the same dlt code on the dltHub platform — no infrastructure to maintain. The prompt above already ends with "run it on dltHub", so your agent can take it there directly.

• Deploy & schedule — run the pipeline as a managed job with automatic retries.
• Monitor — observable job queues, alerting, and load metrics for every run.
• Transform — promote raw SAP BW Open Hub Application Server loads into governed, documented models.
• Visualize & share — explore data in notebooks and publish live dashboards instead of static screenshots.

What other destinations can I load SAP BW Open Hub Application Server data to?

dlt loads into any of these — only the destination argument changes:

Set dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. On the dltHub platform the same pipeline runs against a managed Iceberg lakehouse. See the full destinations list.
