Summary : 
      SAP Note 96732 addresses the enhancement of the client copy tool for DB2/390 databases. Starting from Release 4.0, specific functionalities not present in the standard model are included, necessitating prerequisite reading of this Note before transport request import. The client copy performance for DB2/390 is optimized, though functionality remains untested on other databases. Users encountering issues should first refer to the latest version of the note and available tools in "/general/R3server/abap/note.0096732" on sapservX. For issues requiring a problem message, reference this Note alongside the transport request number, retrievable via Transaction SE38.
