First of all you should try to denormalize this schema, you have a country table with just the CountryID and the Country you should consider adding it to the organization table directly by Country. You should do it with a lot of tables in your model because they are not adding any important data.
As less tables you have the easier to manage the schema.
I know that it is against to all the relational DB theory, but it is the best way to work with qlikview.
