Release 3.0A contains transactions which let you transport reports and forms (in CO-PA also report line structures) to client 000 of another system. When you do that, the system automatically transports all the objects which are dependent on that report or form. Then you can use other functions to copy the client-specific settings to another client.
Note that the reserved name range for objects delivered in the standard R/3 System is: 0* to 9* (forms, reports)
