Informix Error -893

-893 Cannot activate/create object object-name because of its dependencies.

The user has issued a SET statement to set a database object to the enabled or filtering object mode, or the user has issued a CREATE INDEX, CREATE TRIGGER, or CREATE TABLE statement to create a database object in the enabled or filtering object mode. However, this object needs other disabled objects. For example, before enabling a referential constraint on a table, the user must first enable the indexes that the constraint needs.
