Swedbank ISO20022 payment - swedish bankgiro

I am setting up ISO payments in IFS 10 for Swedish bank Swedbank. I want to use the swedish bankgiro account both for the cash account in IFS and also for the suppliers bank account in basic data

Now testing the ISO20022 xml file comes out saying the account number is an IBAN account number which makes the file incorrect

Which field in IFS controls the tag <DbtrAcct>    <Id>   <IBAN> to be set. I want this to be a regular bank account instead

Thanks

Per
