How To Fix BF00018 - Bank key not found; see long text

SAP Error Message - Details

• Message type: E = Error

• Message class: BF00 - FI: Application base reports

• Message number: 018

• Message text: Bank key not found; see long text

What causes this issue?

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.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Add the SWIFT code and then choose <LS>Generate Bank Details</> again.
Alternatively, use the F4 help to select the bank key and then choose
<LS>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 <LS>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 <LS>Bank Key </>field empty and
choose <LS>Generate Bank Details </>again.
