Overview

This node integrates with the SAP Business One Service Layer (version 7) to manage inventory-related operations. Specifically, for the Inventory Gen Entrie resource and the Cancel operation, it allows users to cancel an existing inventory generation entry in SAP B1.

Typical use cases include:

  • Automating cancellation of inventory entries that were created in error.
  • Integrating SAP B1 inventory management into broader workflows where inventory adjustments need to be reversed programmatically.
  • Streamlining inventory control processes by enabling cancellations directly from n8n without manual intervention in SAP B1.

For example, if a user mistakenly posts an inventory generation entry, this node can be used to cancel that entry by providing its primary key (DocEntry), ensuring data consistency and avoiding manual corrections.

Properties

Name Meaning
DocEntry / Key The primary key identifier of the inventory generation entry to cancel. This is required to specify which entry to cancel.

Output

The node outputs JSON data representing the response from the SAP B1 Service Layer after attempting the cancellation. The structure typically includes details about the cancelled inventory entry or an error message if the cancellation failed.

Example output JSON might look like:

{
  "DocEntry": 123,
  "Status": "Cancelled",
  "Message": "Inventory generation entry successfully cancelled."
}

If an error occurs, the output JSON will contain an error field with the error message.

The node does not output binary data.

Dependencies

  • Requires connection to an SAP Business One Service Layer API endpoint.
  • Needs credentials including:
    • Base URL of the SAP B1 Service Layer.
    • Username and password for authentication.
    • Company database name.
  • The node authenticates by sending a login request to the SAP B1 Service Layer and manages session cookies for subsequent requests.

Troubleshooting

  • Authentication errors: If login fails, verify the base URL, username, password, and company database are correct. Also ensure the SAP B1 Service Layer is accessible from the n8n environment.
  • Invalid DocEntry: Cancellation requires a valid primary key. If the provided DocEntry does not exist or is incorrect, the API will return an error.
  • Permission issues: Ensure the SAP B1 user has sufficient permissions to cancel inventory entries.
  • Network/SSL issues: The node disables SSL certificate verification (rejectUnauthorized: false). If you encounter network errors, check connectivity and consider security implications.
  • Error messages: Errors returned from SAP B1 are passed through in the output's error field. Review these messages for specific causes.
