Promotion organization
Promotions are owned by stores. They can be uniquely identified by the store they belong to, their name, version and revision. Promotions are organized into Promotion Groups, which are also owned by stores. Each promotion belongs to one, and only one, promotion group. Optionally, a promotion can be associated with a campaign.
Promotion policies can be optionally associated with promotion groups. When a policy is associated with a promotion group, it applies to all promotions in that group. When a promotion policy is not associated with any group, it is considered global, which means it is applicable to any and all promotions. Promotion policies are owned by individual stores as well.
Currently the following promotion groups and policies are available in WebSphere Commerce by default:

- The tools to determine which shipping promotion was applied to an order is not available at present. But when the shipping promotion for an order is expired, it will be removed from the order on running OrderCalculate or OrderPrepare.
