In the publication, you can place an URL to external publication at the bottom in the Additional Information section.
Once you have maintained it, the job advertisement will still appear in your job list. When a potential candidate clicks on the link, he or she will be redirected to the page that was stored as an external link. This becomes interesting if you want to bring together several companies with several d.vinci systems - on one widget, for example. The potential candidate sees the list of job offers and selects one of them. Depending on which one he or she selects - it is possible that his or her application will arrive in d.vinci system A - or in d.vinci system B.
