Open codeunit 5416200 (NETRONIC VPS Management) in the Dynamics NAV Development Environment and search for the function LoadLanguageDependentOptions.
Select View —> C/AL Locals and open the tab "Text Constants" which offers a list with all the texts you need for our Visual Service Scheduler to translate into your language. By default, we provide an English and a German version.
Now, mark each line and click the three bullets ("…"). The window "Multilanguage Editor" appears where you can provide your local translations of the selected texts.
Finally, please compile the codeunit.
