The table in question was partitioned. There are probably two partitioning methods in use here, either range partitioning or list partitioning. If the table was range partitioned, then you are attempting to insert a row that has a key value outside of the defined ranges. If the table was list partitioned, then you are attempting to insert a row that has a key value outside of the list of key values. The ALL_PART_TABLES view can tell you if the table is range partitioned or list partitioned. The ALL_PART_KEY_COLUMNS view will tell you the partition key columns. The ALL_TAB_PARTITIONS view will show you the ranges or list of values for the partitioned table. Once you know which values are allowed, you will be able to determine why the row could not be inserted into the table.
