Microsoft Dynamics NAV 2013 & Above – Cross Reference – Setup Item References No for Customers and Vendors.

Target Audience: NAV User, Functional Consultant

Applied to Area: Sales Process and Purchase Process

Function: Associate customer or vendor item number with own internal item number

Description: It is common that our own Inventory Item-no will be different from our Customer-item-no or Vendor-item-no, likewise the item-description may also be different.

There are times, when we want to raise a PO to our vendor, we may have to use the vendor-item-no and likewise when we want to raise a Sales Quotation, we may have to use the customer-item-no.

There is a method in NAV where you can associate the vendor-item-no and customer-item-no to our own Inventory-item-no – this is done through the Item-Cross-Reference to “tag” our Inventory-item-no to the Vendor-item-no and Customer-item-no and associate item-description.

By doing so, we can raise PO and SQ using the vendor-item-no and customer-item-no together with their description.
