If your model has an Informix DS target and a table has a user-defined datatype or a list, it may generate an error like the following:
[ChangeApplier13] ERROR:06413: Sql exception occurred: Error creating a statement:
ERROR DETAILS >>> [Error:-999] [State:IX000] Message: Not implemented yet.Executing any SQL DML statement, such as select count(*), against the table will prevent this from happening. The statement must be executed in the context of the database in which the table resides; it is not sufficient to specify a fully qualified name from a different database.
