Enhancement: Enable Functional Dropshipping Flow with Automatic PO and Vendor-to-Customer Transfer

Summary

The dropshipping flow is currently not working. To support a complete dropshipping workflow, products should allow vendor configuration through a Purchase tab, enabling automatic Purchase Order (PO) generation and vendor-to-customer delivery.

Currently, there is no way to configure vendor information on the product, which prevents the dropshipping flow from functioning correctly.

Proposed Enhancement

Implement full dropshipping workflow support, including:

• Add a Purchase tab to the product form.
• Allow users to configure vendors for products.
• Automatically create a Purchase Order (PO) when a Sales Order is confirmed for a dropship product.
• Generate a dropship transfer from Vendor → Customer after PO confirmation.

Steps to Reproduce Current Issue

1. Create a new product.
2. In the product Routes, select Dropship.
3. Observe that there is no Purchase tab available to configure a vendor.
4. Create a Sales Order using the product.
5. Confirm the Sales Order.

Current Behavior

• The dropshipping flow does not work.
• No Purchase tab exists on the product to configure vendors.
• A Purchase Order is not automatically created after Sales Order confirmation.
• No dropship transfer is generated.

Expected Behavior

1. User creates a product and enables the Dropship route.
2. User adds a Vendor in the Purchase tab.
3. User creates and confirms a Sales Order with the product.
4. A Purchase Order should be automatically created.
5. After confirming the PO, a dropship transfer should be generated.
6. The transfer locations should be:
   • Source: Vendor
   • Destination: Customer

Expected Flow

Product (Dropship Route + Vendor) → Sales Order → Auto-generated Purchase Order → Dropship Transfer (Vendor → Customer)

Impact

This enhancement is required to enable a complete dropshipping workflow, allowing products to be shipped directly from vendors to customers without passing through warehouse inventory.
