Hi Thomas

Thank you for your reply. I thought I would try and find which field was
missing and did

select * from rdb$user_privileges p where
not exists(select * from rdb$relation_fields f where
f.rdb$field_name=p.rdb$field_name)
and p.rdb$field_name is not null

but it returned nothing.

Short of attempting to revoke and reinstate all privileges is there a way of
finding the rogue record?

Regards
Paul
