Dear Michiel, 
For your requirement to automatically split one sales order into separate pickings for dry, frozen, and cool products, here's the recommended approach:

Solution 1: Using Product Categories + Routes (No Custom Code)

1. Set Up Product Categories:
   • Create categories: Dry, Frozen, Cool
   • Assign each product to the appropriate category
2. Configure Routes:
   • Go to Inventory → Configuration → Routes
   • Create 3 separate routes (e.g., "Pick Dry", "Pick Frozen", "Pick Cool")
   • For each route:
     • Add rule: "When to trigger" = "Move from stock to pack"
     • Set source/destination locations matching your storage (WH/Stock/Dry, etc.)
3. Assign Routes to Products:
   • For each product, specify the appropriate route in:
     • Inventory tab → Route → Add your custom route

Solution 2: Using Operation Types (Alternative)

1. Create Separate Operation Types:
   • Inventory → Configuration → Operation Types
   • Add "Pick Dry", "Pick Frozen", "Pick Cool"
2. Configure Locations:
   • Ensure each storage area has correct location type
   • Set default operation types for each location

Why Your Current Setup Might Be Blocking

The issue likely occurs because:

• All products are being allocated to the first operation
• The system sees the same stock moves competing for the same source location

Best Practice Recommendation

1. Use Solution 1 (Product Categories + Routes) for:
   • Automatic splitting of pickings
   • Clear separation in warehouse operations
   • Minimal maintenance
2. Add Visual Indicators:
   • Use colored labels or custom fields to distinguish product types
   • Consider barcode prefixes for different categories

Testing the Solution

1. Create a test sales order with all 3 product types
2. Confirm the order
3. Verify that:
   • 3 separate pickings are generated
   • Each picking contains only products of one type

Locations are correctly assigned

Yes, it's possible to generate 3 separate picking orders (for dry, cool, and frozen products) from one sales order — but not 100% automatically out of the box . It requires either precise configuration or a small customization.

Reason:

Odoo doesn't natively split deliveries by product type. However, we can achieve it using:

• Separate storage locations (eg, WH/Stock/Dry, WH/Stock/Cool, WH/Stock/Frozen)
• Putaway rules (to route products to their correct storage)
• Custom delivery routes (to create separate pickings)

we can set up the system so that each sales order creates 3 separate picking lists — one for Dry, one for Cool, and one for Frozen products.

However, this behavior is not fully automatic in standard Odoo.

By default, Odoo generates one delivery order per sales order. To split pickings by storage condition (Dry/Cool/Frozen), we need to either:

• Use advanced warehouse configuration (locations + routes + putaway rules), or
• Apply a small customization to automatically split the delivery based on product type.

We recommend the customization for the most reliable and scalable solution, especially if this process is core to your business
