+=======================
+Process Batch Transfers
+=======================
+
+Batch picking allows a single picker to handle a batch of orders,
+reducing the number of times he must visit the same location. In Odoo,
+it means you can regroup several transfers into the same batch
+transfer, then process it, either via the barcode application or in the form view.
+
+Create a Batch Transfer
+=======================
+
+To activate the batch picking option, go to :menuselection:`Inventory
+--> Configuration --> Configuration` and enable *Batch Pickings*.

+
+Then, go to :menuselection:`Inventory --> Operations --> Batch
+Transfers` and hit the create button.

+
+Now, determine the batch transfer responsible and the type of transfers
+you want to include in the batch. To add the types of transfers, click on *Add a line*.

+
+In the example below, a filter was applied to only see the transfers that are in the *Pick* step.
+After that, the different transfers that needed to be included in the batch transfer were selected.

+          to the batch transfer
+
+To see the products to pick for the different transfers, click on
+*Select*. If *Multi-locations* has been activated, the document also shows the locations they have 
+been reserved from.

+
+Create a Batch Transfer from the Transfers List View
+====================================================
+
+From the *Transfers List View*, select transfers that should be
+included in the Batch. Then, select *Add to batch* from the *Action*
+list.
+

+
+Next, determine if you want to add the transfers to an existing draft
+batch transfer or create a new one.

+
+Process a Batch Transfer
+========================
+
+While gathering the products, you can edit the batch transfer and update
+the *Quantity done* for each product. Once everything has been picked, select
+*Validate* so the different transfers contained in the batch are validated
+too.
+

+
+In case all the products cannot be picked, you can create backorders for each individual transfer 
+which couldn’t be completely processed.

+
+Process a Batch Transfer from the Barcode app
+=============================================
+
+Enter the *Barcode* application, select the *Batch Transfers* menu.
+
+.. image:: media/batch_transfers_11.png

+    :alt: View of the Odoo Barcode app dashboard
+
+Then, you can enter the batch transfer on which you want to work. Batch
+transfers can easily be grouped per responsible if necessary.

+
+In the batch transfer, products are classified per
+location. The source document is visible on each line and a color-code
+helps differentiate them.

+last page) to mark the batch transfer as done.
