This interface pattern is used to perform actions that operate on business object (BO) data. There are typically only a few parameters contained in the the request so that the action can be performed.
Further comments:
The interface pattern shows those actions that are used most frequently:
Release <BO>
Deactivate <BO> (For example, for an action on master data objects that are just to be deactivated, rather than deleted.)
If you need checking actions, name them according to the following schema: Check <BO> <action in substantiated form>. The graphic above shows an example for the Deactivate action.
