Supplier Categories allows you to bundle your suppliers into groups. It is particularly useful for those customers with hundreds of suppliers. You can choose how you group your suppliers, and suppliers can be in more than one group.
Firstly, show Supplier Categories in Supplier Details & New PO Request page
This is done by saying yes to Show Supplier Categories at SetupApps SupplierHub Settings.
Setup Supplier Categories
In SupplierHub under SetupApps select Categories to add a Category (group) and then place suppliers into that group.
How it works
When you add a new Supplier map the supplier with the Category you created.
When raising a purchase order firstly select the Category, and then the Supplier from the suppliers in that group.
