3126978 - The error message 'Bank key not found' occurs in vendor master for country SE


The IBAN ONLY functionality is activated in the system. 

Once the IBAN is entered for country SE, the following error occurs: 


Bank key not found; see long text

Message No. BF00018


It was not possible to complete the generation of the bank data from the IBAN as the system could not find a matching bank key. Either the system was only able to find some or none of the bank key from the IBAN, or the banks are managed under a different bank key type for each country in the SAP system that is not in the IBAN, or the bank is not yet in the SAP system.

Even if you want to store the IBAN only, and not the account number, the system still requires that the IBAN be assigned to a bank key.

•Add the SWIFT code and then choose Generate Bank Details again.
•Alternatively, use the F4 help to select the bank key and then choose Generate Bank Details again.
•Alternatively, enter the bank key directly if you know what it is, and if the bank is not yet in the SAP system. Now choose Generate Bank Details again. Once you have done this, you can create the bank if you are authorized to enter new bank data. Note the setting of the bank key for each country in the field checks for those countries (transaction OY17):
◦If the bank number is used as a bank key (characteristic 1), enter the bank number.
◦If, for example, the SWIFT code or another external key is used (characteristic 4), enter this key.
◦If the bank key is assigned internally (characteristic 3), then you cannot enter this directly. Leave the Bank Key field empty and choose Generate Bank Details again.
