As per the Norwegian booking Act all accounting data must be physically stored in either Norway, Sweden, Denmark, Iceland or Finland. When creating a Business Central environment under a tenant based in North Europe, there isn't the ability to know precisely which country the data is stored in.

Under North Europe, there are also Estonia, Latvia and Lithuania.
The Norwegian booking Act also requires a precise street address for where the data is kept.

For the time being a workaround for Norwegian Partners using Business Central Online is to set up an Azure Storage account in order to export the database on a regular basis.
Yes, it is a workaround, but not very convenient in the long run.

It would be wonderful if some form of compliance can be created from Microsoft's end in regards to the Norwegian Booking Act.
