ORA-14855
Table is already a list partitioned table and not an automatic list partitioned table.
Cause
An attempt was made to unset automatic list partitioning on a table that was already a manual list partitioned table. A conversion from auto list partitioning to (manual) list partitioning using SET PARTITIONING MANUAL will only succeed for auto list partitioned tables.
Action
Do not use SET PARTITIONING MANUAL for manual list partitioned tables. There is no need to unset auto list partitioning for such a table. The table already has the desired list partitioning setup.

Cause

Action
Use SET [SUB]PARTITIONING MANUAL on an autolist (sub)partitioned table.
