While importing the development objects, the program tp does not terminate (normally it runs a few minutes). After canceling with (Ctrl-C), the following message is displayed in the SLOG file.
Background job RDDIMPDP could not be started or terminated abnormally
The import of development objects is executed by job RDDIMPDP. This is usually event-controlled and triggered by the event "SAP_TRIGGER_RDDIMPDP" of the program tp. In this case, starting the job with the event does not work - tp consequently waits infinitely.
Verify that the event "SAP_TRIGGER_RDDIMPDP" has been defined (SM64).
Verify that the entries for the event control are correctly set in TPPARAM.
