ORA-31441: table is not a change table
Cause: User attempted to execute the DROP_CHANGE_TABLE procedure on a table that is not a CHANGE table. This can also occur when a CHANGE table object has been orphaned. CHANGE tables can become orphaned after a CREATE_CHANGE_TABLE failure or an incomplete DROP_CHANGE_TABLE
Action: Check spelling. If error was due to an incorrect name, then retry the procedure using the correct name. To drop a table that is not a CHANGE table, or an orphaned CHANGE table, use the DROP TABLE DDL command instead
