Inventory Extensions

Custom inventory features for stock management.

Critical Configuration: MTO Route

The Replenish on Order (MTO) route MUST be enabled for the SO → PO → Delivery → FSM workflow to function correctly. Without MTO, confirming a Sales Order will NOT automatically create a Purchase Order.

MTO (Make to Order) Configuration

The MTO route ensures that each Sales Order automatically creates a Purchase Order for the vendor. This is essential for the window blinds workflow where products are custom-ordered per customer specifications.

Why MTO is Required

flowchart LR
    A[Sale Order] -->|MTO Route| B[Purchase Order]
    B --> C[Receive Products]
    C --> D[Delivery Order]
    D -->|Validate| E[FSM Order]

Without MTO enabled: - Sales Orders do NOT create Purchase Orders - You must manually create POs - The SO → PO link is broken

Step 1: Unarchive the MTO Route

The MTO route is archived by default in Odoo 15. You must unarchive it first.

  1. Go to Inventory → Configuration → Routes
  2. Click Filters → Archived to show archived routes
  3. Find Replenish on Order (MTO)
  4. Select it and click Action → Unarchive

Alternatively: 1. Go to Inventory → Configuration → Routes 2. Remove the "Archived" filter from the search bar 3. The MTO route will now appear in the list

Step 2: Configure Products for MTO

Each product that should trigger automatic PO creation needs MTO configured:

  1. Go to Inventory → Products → Products
  2. Open the product
  3. Click the Inventory tab
  4. In the Routes section, enable:
  5. Replenish on Order (MTO) ✓
  6. Buy ✓

Both Routes Required

MTO does NOT work alone. You MUST also select the Buy route (for purchased products) or Manufacture route (for manufactured products).

Step 3: Configure Vendor

For MTO + Buy to work, the product must have a vendor configured:

  1. On the product form, go to Purchase tab
  2. Add a vendor in the Vendors section
  3. Set the price and delivery lead time

MTO Workflow

When MTO is properly configured:

Step Action Result
1 Confirm Sale Order Draft Purchase Order created
2 Confirm Purchase Order Receipt (incoming) created
3 Validate Receipt Products in stock
4 Validate Delivery FSM Order created

Verify MTO is Working

After confirming a Sales Order:

  1. Check Purchase → Orders → Purchase Orders
  2. A new draft PO should exist with:
  3. Origin = Sales Order number (e.g., "SO0001")
  4. Vendor = Product's configured vendor
  5. Products = Same as SO lines

Common Issues

Problem Cause Solution
No PO created after SO confirm MTO route not enabled on product Enable MTO + Buy routes
No PO created MTO route still archived Unarchive the route
Error: No vendor Product missing vendor Add vendor in Purchase tab
POs merging together Standard Odoo behavior See bi_product_dimension for 1 SO = 1 PO fix
