Single-object controlling: The account assignment object is the
receiver of the controlling object's settlement rule, which is to be
created. The sender stands for the controlling object here, whose
controlling area is specified by the requesting object. The controlling
object is the internal order that is to be created, or that has already
been created to which the account is directly assigned.
Controlling on the account assignment receiver: The account assignment
object should be the controlling object. The account should be assigned
directly to this object.
The requesting object has specified the account assignment object and
the sender controlling area. The account assignment object is assigned
to the controlling area &v1& and the sender is assigned to the
controlling area &v2&. The two controlling areas must be the same.
