Odoo does for sure know the danish currency and therefore you'll probably get your error when adding it another time manually.

Please check your currency settings:

- Go to "Settings/Configuration/Accounting" and check "Allow multi currencies"

- Go to "Accounting/Configuration/Miscellaneous/Currencies" and activate DKK currency.

- Go to your Company settings and choose DKK as company currency

- If you do not need multi currencies, you can uncheck "Allow multi currencies" again.

Thanks

All currencies are activated (right colum).

How do I define a purchase in Euro (procurement) with my base currency in DKK.
