Oracle DB Error ORA-02296 cannot enable (string.string) - null values found

The following is the cause of this error:

An ALTER TABLE command with an ENABLE CONSTRAINT clause failed because the table contains values that do not satisfy the constraint.

Action you can take to resolve this issue: Make sure that all values in the table satisfy the constraint before issuing an ALTER TABLE command with an ENABLE CONSTRAINT clause. For more information about ALTER TABLE and ENABLE CONSTRAINT, see the Oracle9i SQL Reference.
