Each supplier will need to generate a master list of all the different packaging types they intend to use to deliver parts. These packaging types include base containers, dunnage, pallets and top caps. Once you have defined your supplier packaging type list requirements using an Excel spreadsheet, a Whirlpool administrator will assign or add those packaging types to your trading partner ID so that when you filter packaging type by supplier those packaging types will appear.  This section in the Supplier User Guide describes the process of creating your supplier packaging type list.
