Overview
This node interacts with the SAP Business One Service Layer (version 8) to manage various business documents and entities, specifically here focusing on the Product Tree resource. The Close operation allows users to close a Product Tree document by its unique identifier (DocEntry). Closing a document typically marks it as finalized or completed in SAP B1, preventing further modifications.
Common scenarios for this node include automating production workflows where product trees need to be programmatically closed after completion of certain steps, integrating SAP B1 document lifecycle management into broader automation pipelines, or batch processing multiple product trees for closure.
Example use case: After manufacturing processes are confirmed, an automation workflow closes the corresponding Product Tree documents in SAP B1 to update their status and trigger subsequent accounting or inventory updates.
Properties
| Name | Meaning |
|---|---|
| DocEntry | The unique identifier of the Product Tree document to close. This is required to specify which document to close. |
Output
The node outputs JSON data representing the response from the SAP B1 Service Layer API after attempting to close the specified Product Tree document. The structure typically includes details about the updated document status or any error messages if the operation failed.
If the operation succeeds, the output JSON will contain confirmation of the document being closed. If there is an error (e.g., invalid DocEntry, network issues), the output JSON will contain an error field with the error message.
No binary data output is produced by this node.
Dependencies
- Requires connection credentials to the SAP Business One Service Layer API, including:
- Base URL of the SAP B1 Service Layer.
- Username and password for authentication.
- Company database name.
- The node performs a login request to obtain session cookies used for subsequent API calls.
- The environment must allow HTTPS requests to the SAP B1 Service Layer endpoint.
- No additional external libraries beyond standard HTTP request helpers provided by n8n are needed.
Troubleshooting
- Authentication errors: If login fails, verify that the username, password, and company database are correct and that the SAP B1 Service Layer is accessible.
- Invalid DocEntry: Errors indicating the document was not found usually mean the
DocEntryvalue is incorrect or the document does not exist in the specified company database. - Network or SSL issues: The node disables strict SSL verification (
rejectUnauthorized: false) but network connectivity problems or firewall restrictions can still cause failures. - API errors: The SAP B1 Service Layer may return errors if the document cannot be closed due to business rules (e.g., already closed, dependencies). Review the error message returned in the output JSON for guidance.
- Session handling: The node manages session cookies internally; if sessions expire quickly, consider adjusting SAP B1 server settings or re-authenticating more frequently.
