you might want to "disable" the FK's before loading. This will speed up the loading, and it will not upset you with ugly error messages. After loading... enable keys.

It is probably a question of timing when Child records are loaded before Parents. It can be a question of table order or even record order (self referencing relationship). Once the data is loaded, enforcement of the constraint is easy because all of the data exists.

Okay guys,

Have foreign keys defined on large dw tables. When loading get foreign key errors. However, after load
(w/o change in data and supposedly data it was barking
on) could create fk's just fine on the same data elements involving the same data - I SWEAR. This does not make sense to me. Any ideas?
