Customer and vendor roles
Use customer and vendor roles 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
A corporation, Two Rivers, has a location in Germany and a location in France, they can share inventory using roles. If Germany is out of an item, then it can request the item from France. Then, Two Rivers in Germany becomes the customer and Two Rivers in France the vendor.
