Entry through another Schengen country is possible if the visa's validity, number of entries and territorial scope allow it. First entry does not always determine which country should issue the visa. If Denmark is genuinely the main destination by duration or purpose, entering through Germany can be consistent with that application. Border authorities may nevertheless ask about accommodation, the travel purpose and onward arrangements. The German portion should be disclosed rather than omitted. If Denmark will no longer be visited or the main destination has changed materially, seek instructions from the relevant authority rather than assuming the original explanation remains sufficient.
