SAP B1 Service Layer 8 - Produccion

Overview

This node interacts with the SAP Business One Service Layer (version 8) to manage various business documents, including Inventory Transfer Requests. Specifically, the Close operation for the Inventory Transfer Request resource allows users to close an existing inventory transfer request document in SAP B1.

Closing a document typically means finalizing it so that no further changes are allowed, marking it as complete in the system. This is useful in scenarios where inventory movements need to be confirmed and locked after verification.

Practical example:
A warehouse manager uses this node to close an inventory transfer request after physically moving stock between warehouses, ensuring the document status reflects the completed transfer in SAP B1.

Properties

Output

The node outputs a JSON object representing the response from the SAP B1 Service Layer after attempting to close the specified Inventory Transfer Request. This typically includes confirmation details or error information related to the close operation.

No binary data output is produced by this node.

Example output structure (simplified):

{
  "DocEntry": 123,
  "Message": "Document closed successfully",
  ...
}

Or, in case of error:

{
  "error": "Error message describing what went wrong"
}

Dependencies

• Requires connection to an SAP Business One Service Layer endpoint (version 8).
• Needs credentials including:
  • Base URL of the SAP B1 Service Layer.
  • Username and password for authentication.
  • Company database name.
• The node performs login to obtain session cookies before making API requests.
• No additional external dependencies beyond the SAP B1 Service Layer API.

Troubleshooting

• Authentication errors:
  If login fails, verify the SAP B1 credentials (username, password, company DB) and network connectivity to the Service Layer endpoint.

• Invalid DocEntry:
  Providing a non-existent or incorrect DocEntry will result in an error from SAP B1 indicating the document was not found.

• Permission issues:
  Ensure the user account has sufficient permissions to close inventory transfer requests.

• API errors:
  The node returns error messages from SAP B1 directly in the output JSON under the error key. Review these messages for clues on misconfiguration or invalid operations.

• SSL certificate warnings:
  The node disables SSL certificate verification (rejectUnauthorized: false). In production, ensure secure connections or adjust accordingly.
