Middleware (BC-MID)

An optional element of a business object (BO) node that describes an operation performed on that node. When you perform the action, you must specify: The name of the action; the BO node on which the action is to be performed; the key for the instances on which it is to be performed; any input parameters that the action requires. The action then returns the set of objects that have been created or changed by it. Actions are always implemented by a specific method in the action interface. Actions can and should be reused in more than one BO node (not necessarily in the same BO).
