Facilitate Picking Using Invoices with ERP systems

Rather than using pick lists, some companies pick products using one ply of invoices. For a distribution operations dealing with a huge variety of SKUs, it is likely that SKU number would be classified according to product groups like (dry goods, chilled or frozen products). To facilitate picking, it may be better for the SKU number on invoices to be shorted alpha-numerically.

For example, in Microsoft GP, sorting by SKU number on invoice is
MS Dynamic GP> Tool > Customise > Report Writer > Reports > Invoice History & New Invoice > Sort > Choose Item number column > Descending
