Diagnosis
You try to create a new dependent object for a given parent objectinstance. However, for the given parent object only one dependentobject instance is allowed due to the object type definitions or othergeneral restrictions.
Examples:

• you try to create a new replication object for a BDoc type for which
the corresponding replication object has already been defined

• you try to create a new publication for a replication object of type
bulk or simple bulk although there is already a publication on thesystem which contains this replication object

• you try to create a new subscription for a publication of type bulk or
simple bulk although the corresponding subscription already exists.
Therefore the object creation process cannot be executed.

System Response
Instead of creating a new object instance the corresponding existingobject instance is returned.
