Installation ERP 2005 - DB Instance Error

AIX/Oracle.

The IMPORT ABAP step fails with error. "Import Monitor jobs: running 0, waiting 1, completed 33, failed 4, total 38."

The four that "fail" all have the same error; but look like the load was successful

Is ORA-1403 when accessing table SAPUSER my problem? Or is there something else?

Thanks
