Inventory : Inventory Workflows: 2-Step Receiving
Purpose
The purpose of this documentation is to outline the process of implementing 2-Step Receiving in Odoo Version 13. In 2-Step Receiving, products are first received to an internal Input location before being transferred to their specific Stock location.
Process
To get started, navigate to the Inventory application.
Once there, go to CONFIGURATION > SETTINGS.
Scroll down to the Warehouse section and check Multi-Step Routes. Then, click SAVE.
Next, go to CONFIGURATION > warehouses.
Select the Warehouse you wish to configure with 2-Step Receiving.
On the Warehouse template, click edit.
Under Shipments > Incoming Shipments, select "Receive goods in input and then stock (2 steps)."
When done, click Save.
Selecting the 2-Step option means that Odoo will create an Input location to receive goods into. You can see this new location by navigating to Configuration > Locations, and using the search bar to search for "Input."
By selecting the location and clicking edit, you can change the name of the "Input" location if needed.
Receiving Products
Once you have set up 2-Step Receiving on your Warehouse, you will see its effects on your receipts.
To get started, navigate to the Purchase application.
Once there, create a Purchase Order for a storable product. For information on how to create Purchase Orders, please refer to the Purchase Orders documentation.
Once you have confirmed the order, click either the Receipt smart button or RECEIVE PRODUCTS.
On the receipt, in the Detailed Operations tab, you will see that the To field is populated with the WH/Input location.
Click edit. Under Detailed Operations, enter the quantity of the product you have received in the Done field. 
When done, complete the receipt by clicking validate. Now, your goods are in the Input location.
When using 2-step receiving, Odoo automatically creates a transfer that will move the received product from the Input location to the primary Stock location on your company's receipt Operation Type. Follow the steps below to validate that transfer and complete the receipt of your goods.
Processing the Internal Transfer
To get started, navigate to the Inventory application.
Locate the Internal Transfers card for your Warehouse. Click # to process.
From the list of internal transfers, select the transfer that lists your Purchase Order as the Source Document.
On the internal transfer, you will see that the From and To fields are populated with the WH/Input and WH/Stock locations, respectively.
Once you have reviewed the internal transfer, click validate. Then, in the modal window, click apply.
Good to Know!
Putaway Rules
If you have configured a Putaway Strategy on the Product or Product Category of the product being received, they will take effect once you validate the transfer. The destination location on the transfer will still reflect the main Stock location, but once processed, the products will be moved to their more specific stock locations.
For more information on Putaway Rules, please refer to the Putaway Rules documentation.
Now you can review the stock moves for the receipt to verify that the products ended up in the intended locations.
