If more than one supplier is assigned to an Item, you can designate one of them as the preferred/favorite supplier. When creating a Purchase Order Suggestion, this supplier will be automatically selected for the item—unless another selection is explicitly made. Only one supplier can be defined as the preferred supplier.
To set a preferred supplier:
Open an Item from the Item Management list and navigate to the Suppliers tab.
Select a supplier from the list and click Favorite.
Clicking the Favorite toolbar button again or marking another supplier as preferred will deactivate your previous selection.Click Save to apply the changes.
The preferred supplier is marked with a star icon in the list.
