Material listing and exclusion lets you control which materials specific customers may or may not buy. For example, if you create a listing of products for an individual customer, the customer may only order products on the list. If you create an order for this customer, a check is carried out during item entry to make sure that the material entered is on the list. You can also specify material exclusion for a particular customer. The customer may not order excluded materials from you.

It is possible to create an analysis log in material listing and in material exclusion.
