Alert:
In Step 5, before printing, click Check Availability to ensure that Demand and Quantity match. Then, proceed to print Picking Operations.
(Items with a quantity of 0 will not be included in the Picking Operations printout.)

✅  Operator Goal: Understand how to create, confirm, and flow through PICK ➜ OUT.

Suggestion: Add a note that confirmation locks in reserved stock. Staff should double-check product lines before confirming, especially during peak order volume.

1. Create Sales Order (SO)

Go to Sales → Orders → Create and enter customer + products.
This is the starting point of every flow.

2. Add Order Lines

Fill in products, quantities, prices, taxes, and discounts.
Check carefully before saving.

3. Save Draft

The order is now in Quotation state.
No stock is reserved yet.

4. Confirm Sales Order

Click Confirm.
This generates Transfers (PICK + OUT in 2-step delivery).

5. Review Generated Transfers

Go to the Delivery smart button on the SO.

Two records will show: PICK (Internal Transfer) and OUT (Customer Delivery).

6. Understand PICK vs OUT

• PICK (WH/PICK/xxx): Moves stock from WH/Stock → WH/Output.

• OUT (WH/OUT/xxx): Ships stock from WH/Output → Customer.

7. Reserve Stock

When the SO is confirmed, Odoo reserves stock automatically (if available).
Reserved stock is visible on the PICK.

Demand → This is the quantity requested by the SO.

Quantity → This shows how many units are actually reserved from stock.

✅ Operator Action:

If the reserved quantity is less than the demand, click Check Availability.

• This tells Odoo to allocate whatever stock is available in the warehouse.
• If full stock exists, the Quantity column will match the Demand.
• If not, the system will partially reserve what’s available, and you’ll need to wait for replenishment or adjust.

8. Warehouse Confirms PICK

The warehouse operator confirms PICK is ready.
This is the pivot step — once validated, stock physically leaves WH/Stock.

9. Validate PICK

Click Validate on the PICK DO.
This decreases stock from WH/Stock and increases WH/Output.

10. Check OUT Order

Once PICK is validated, Payments and carrier information are confirmed, and then OUT DO can now be validated by shipping staff.

11. Validate OUT (Delivery to Customer)

Click Validate on the OUT DO.
This decreases WH/Output and finalizes delivery to the customer.

✅ Best Practices Summary

• Always double-check order lines before confirming.
• Remember: confirmation locks and reserves stock immediately.
• Review both generated transfers (PICK & OUT) after confirmation.
• Understand the flow: PICK = Stock → Output, OUT = Output → Customer.
• Validate PICK only when the stock is physically ready to move.
• Treat PICK validation as the pivot point — after this, stock is committed.

✅  Operator Goal: Know when edits apply and when they don’t.

You included the ability to adjust quantities or add/remove products, with changes cascading to the Delivery Order

Suggestion: Clarify that this only works if the DO is not validated yet. Once the PICK is validated, edits won’t affect that transfer.

⚠️ Operators: Always check the status of the PICK before editing a confirmed SO.

1. Edit SO Before Validation

If changes are needed, you can edit product lines before PICK is validated.
Quantities and products will cascade down to Transfers.

2. Add/Remove Lines & Adjust Quantities Before PICK

Adding/removing lines & increasing/decreasing qty works only before PICK validation.
After PICK is done, the flow is frozen. Stock reservations will be updated accordingly.

3. After PICK Validation

⚠️ Once PICK is validated, changes in the SO will not affect stock.
The only correction method is through Returns (Manual Return Flow).

Manual Return Flow

4. Locate the Done PICK

Open the cancelled SO → Transfers → open WH/PICK/xxx.

5. Click Return

On the PICK DO, click Return.

This opens the Return wizard. Confirm quantities to return.

Defaults usually match qty_done.

Confirm the return location and click 'Return'.

6. Creates & Validate Return DO

Wizard generates a new Return of WH/PICK/xxx transfer.

Destination is WH/Stock.

Click Validate.

Stock moves back into WH/Stock.

7. Verify Inventory (optional)

Check Product → Inventory tab.
On Hand should reflect returned quantities.

♻️ Re-Using Cancelled SOs

☑️  Set to Quotation

On the cancelled SO, click Set to Quotation if reusing it.
This reopens it for edits.

9. Confirm Again Carefully

Make adjustments, then confirm again.
⚠️ Only do this if returns are fully completed, otherwise stock will be over-reserved.

✅ Best Practices Summary

• Always check PICK status before editing.
  
• Make changes only before PICK is validated.
• Notify Warehouse to pause PICK if edits are pending.
• Use Manual Return Flow if PICK is already validated.
• Validate Return DOs to restore stock correctly.
• Reconfirm SO only after returns are fully completed.
