Customer and vendor roles
Customer and vendor roles are used to process transactions across companies in a corporation, regardless of country barriers. This way, two companies can act as either a customer or a vendor for each other.
Example
If a corporation, Two Rivers, has a location in Germany and a location in France, they can easily share inventory using roles. If Germany is out of an item, it can request the item from France. Then, Two Rivers in Germany becomes the customer and Two Rivers in France the vendor.
