Connected to: Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production SQL> alter view SYS.KU$_RADM_FPTM_VIEW compile; Warning: View altered with compilation errors. |
The main reason for the problem is that the character set of the radm_fptm$ table is incompatible with the character set of the type called $k_rm_fptm$_t.
When the type ku$_radm_fptm$_t is compiled as follows, the view named SYS.KU$_RADM_FPTM_VIEW can be compiled without any problems and then the export process will be completed succesfully.
