I:Object ID &2 with object type &1, library &3 refers to itself
Message Long Text :
An attempt was made to change an object relation. The object ID &2 with object type &1 is already in the object ID &5 with object type &4 in this object relation. This is impossible. Since within a library list an object cannot be used by two libraries at the same time, the library does not help distinguish between them.
