We have found nothing in F1 Doc on how IFS customers should configure their current local DK business in regards to ISO2022 format that seems to be the current domestic payments / format according to an old Nordea pdf on the interwebs. 
 

Are the DK supplier payment address configured as an IBAN address ? Or is trial and error the recommended  “moment of service” ?

In addition we find no info on how IFS in regards to FI Kort payments vs domestic ISO20022 configuration for local IFS customers.
