SQLCode - 1: Table '_^_^_22072007....._^_^_' not found

This error occurs when inserting rows into a table which has dependant materialized view in SQLA12 db (see attached image for full details).

Any ideas on why this is happening?

This happens on 1 or 2 databases, the rest (90+) is working great.

This is databases which started out as ASA5.5 db's once upon a time.

Otherwise, everything works as it should.
