○       The transport is a deletion

All the entries belonging to the object in TCDOB, TCDOBT, TCDRS, TCDRP, TADIR, ... are deleted, as are generated program sources and DDIC structures.

○       The transport is a regular transport

All the information is taken from the shadow tables TCDOBS, TCDOBTS, and TCDRPS, and then placed in the internal tables TCDOB, TCDOBT, TCDRP, TCDRS and exported..

The generation program RSSCD000 is called. The information is imported and all the steps for generation of the sources and structures are performed.

The resulting messages are returned to the method.
