Transport problems for Z* - InfoObjects

Hello experts,

we do have a problem concerning the transport of BW InfoObjects that have been created in the namespace Z*, e.g. the InfoObject ZD_TEST. We get an error message that the object does not have a connection to the CTO when we try to change the object catalog entry.

1. Is it possible to transport Z* - Objects? (With our customer namespace /***/ everything works fine).

2. If yes, what are the necessary steps?

Thanks in advance.
