Hi @Christian Wellnitz , Thanks for using Microsoft Q&A Platform.
Sorry to hear that you experience this error.
After checking with the product team looks like the Danish is not yet supported in the latest
2023-02-28-preview API. I mean to say models may work well on Danish Invoices, but not the Currency code model on Danish invoices. However, this will be supported soon in the GA (General Availability) API version.
I hope this helps. Let me know if you need additional information.
