The batch-picking facility of odoo16 can be used for managing delivery orders, receipts, and internal transfers. It also reduces the time taken for transportation purposes.
Along with the Batch transfer, Odoo 16 allows us to create Wave transfers which can be used to group move operations in a wave transfer to process them together
You can merge multiple operations like the bulk of receipts or delivery orders to combine them in one form and process those together. So the primary goal of the wave transfer is to group operations from different transfers together in order to increase their efficiency.
