We have following setup:

• Pre-production area, where components are needed to manufacture finished products. On creating manufacturing order, missing goods are ordered automatically.
• Components can be picked/available from our stock, or should be ordered. In that last case the goods should go from inbound area to pre-production area (no extra step through our stock)
• We have 2 step good receipt. When goods are receipt, they should either go to the pre-production area if there is need for them there, or otherwise can go to our stock.

Odoo configuration:

• Locations hierarchy:
• • WH/Stock
  • • WH/Stock/Input (this is different than default Odoo setup)
    • WH/Stock/Warehouse
    • WH/Stock/Warehouse/Sublocation1,2,3,...
  • WH/Pre-production
• Routes configuration:
• • Pick and produce (Sequence = 8):
  • • Action Pull from: WH/Stock -> WH/Pre-production
    • Action Pull from: WH/Pre-production -> Virtual Locations/Production
  • Reception in 2 steps (Sequence = 9)
  • • Action Push to: WH/Stock/Input -> WH/Stock/Warehouse

Resulting behaviour:

• We create a manufacturing order. This automatically creates an Internal Transfer of type Picking. This remains in status waiting if not all components are available.
• When missing components arrive, we complete Operation Receipts. Components are put to WH/Stock/Input
• Instead of linking those components with the existing picking operation, a new Internal Transfer is created of type Storage.
  THIS WE DO NOT WANT: Storage should only happen for products that cannot be linked to existing transfers.

I find this behavior strange, since I put higher priority (lower sequence nr) on the picking route compared to the storage route.

I also tried changing the first action in the "Pick and produce" route to Pull & Push, but this doesn't change the behaviour.

Anyone got any idea what am I doing wrong, or how I can change the behaviour the way we need it? Thanks in advance!
