Allocation is the process of assigning product items from the inventory to shipping orders and then fulfilling the shipping orders from appropriate fulfilment sites such as warehouses.

If Pick ticket is in a draft state it will need to be released to Floor to begin the processes. Releasing to Floor moves the Order from Draft (editable) to a live document.

Notice: In the event your instance of P4 Warehouse is connected via integration with your ERP, orders will not show draft status and cannot be edited from the WMS, edits must take place from the ERP.

To allocate a suitable pick ticket, click on the 'Allocate' button from the pick ticket window as shown below.

Pop-up allocation window is dynamic, meaning the screen only shows the options that are available for this order or group of orders.
