How to setup IBAN for a particular country in PeopleSoft

Hi,

We are on PeopleSoft 9.2. I am trying to set up IBAN for a country. The country code is already added. What is the general process of adding the various information on Banking>>Banks and Branches>> IBAN formats. I can look up a sample IBAN for a country in Google. Is that how this is setup ? Let's say, I look up IBAN for Finland as below-

IBAN	FI21 1234 5600 0007 85
ISO Country Code	FI (Finland)
IBAN Check Digits	21
BBAN	1234 5600 0007 85
Bank Identifier	123456
Account Number	0000078
BBAN Check Digit(s)	5
SEPA Member	Ye

Now, what would be check digit start and check digit length. Is it 18 and 1 respectively ? Or 3 and 2.
