Use of Active Business Objects
Data Transfer Utilities execute inside a client's object manager.
The DTU reuses the current active business objects. It does not instantiate an independent source business object unless directed. This leads to both a leaner memory use and better performance. This is even more so if the destination business object is the same as the source business object. In such a case, no new business objects are instantiated for the business service.
Because of the reuse of active objects, you must exercise caution to preserve the current business object context. For example, the business components must not be in the query state when DTU is launched.
