Hi Dan,
there is a feature to determine pa0003-viekn. If I'm not mistaken it's feature IVWID. I's usually assigning viekn according to country grouping, but there are some exceptions, e.g. for public sector or of course custom amendments. You often get these issues, when the feature is made custom and new country groupings are added.
Anyway, if you assign the right groupings in this feature, you should be fine.
kind regards
Sven
