The Preferred Suppliers function is used to support purchase order automation in
- drop ship,
- just in time (special),
- back-order and
- stock replenishment tasks.
Each of these tasks requires the selection of a preferred supplier to create the related Purchase Order.
Preferred Supplier : Configuration
You can setup preferred Suppliers on the Preferred Suppliers table for each Item in the Item Master.
To configure this table, go to:
PRODUCTS/SERVICES > Items > Select Item > Purchasing/Costs tab > Preferred Suppliers section.
This table stores:
Supplier | A Supplier from your Suppliers List. |
Item Code | The Supplier’s part / SKU code. This code will appear on the Purchasing Documents. When received into the WMS, the system will transform this code into the Sales (internal) Item Code. |

Unit Cost (from Preferred Supplier) |
The unit cost specified on the preferred supplier table located on the Purchasing tab of the respective Item Master. |
Unit Cost (from Item) |
The unit cost specified by you on the respective Item Master. |
