The Inbound Product Catalog Line Table
This field contains a unique common item number that the vendor and customer agree upon.
The common item number is normally a standardized item number, for example, an European Article Number (EAN). What this means is that an item must not have different common item numbers for different vendors.
The common item number can be used to identify items in inbound BizTalk documents or to identify items when updating the Navision Item table that is based on inbound BizTalk product catalogs.
If you want to use this number when you trade with a specific BizTalk partner, you must set up your program accordingly. You can do so by selecting the Common Item Number option in the Sales Item Number Type field.
