The first bug Babic mentions is "lowercase codes in primary key," which requires the developer to take the extra step of setting codes to upper case before shipping them over to NAV. RTC seems to do just that, he adds.

This bug is really not critical. It doesn't even show up often and you can easily work around it. It's in the "so what" category, Babic says.
