IBANK and Swift code

Problems with entering an IBAN and SWIFT from Sweden..

When i am trying to enter bank information of Sweden Vendor by using T.code XK02, I am not able to enter the information in Vendor master data.

The informations are

IBAN: SE1480000818360376747010

SWIFT: SWEDSESS

I checked the length of Characters of IBAN and SWIFT..

Please suggest me what could be the reason, system is not accepting the information.

Regards,

Suresh.
