Setting Up Item Cross-References
In trade sales, the item numbers that the customer and the trade sales supplier use may be different from the item numbers that the system uses to process the order between the customer and trade sales supplier.
To ensure that order and shipment processing among the customer, your company, and the trade sales supplier references the same item:
• Use Item Master Maintenance (1.4.1) first to define items that you reference on trade sales orders.
• If necessary, use Customer Item Maintenance (1.16) to cross-reference the customer item number to your item number.
• If necessary, use Supplier Item Maintenance (1.19) to cross-reference the trade sales supplier item number to your internal item number.
