Bank is invalid - US Country

Hi Friends,

I have an issue with Bank key country settings for US - OY17

When my user is trying to create a Bank master in FI01, the error he is getting is "Bank key is invalid"

I have checked the settings in OY17.

Bank key as 1 = bank number

Bank number length = 9 & checking rule 6

Bank key length = 9 & checking rule 6

But we are unable to create a new bank master

If i change the

Bank Key ....... 4...... Assign externally

then i am allowing to create

Please suggest if i am missing anything in config

Thanks for your advance help

    Dear Nkonnipati,

    You defined the following settings in OY17.

    Country Key US USA

    Bank Key 1 Bank number

    Bank number length 9 6 Maximum value length, numerical

    Also you probably have enabled "Further Check" on Bank Data field.

    Once this indicator is set, then a country-specific check of the bank

    details (bank number, bank account number, bank control key) is carried

    out based on the algorithms defined for that country as per legal


    For USA, the check is carried out on Bank number and in

    your case this Bank number is failing the Bank check and hence you

    are getting the above error. Please contact the concerned bank to get

    the correct bank number else you would have to disable the check on the

    bank data field in OY17 so that no further check is carried out.

    I hope this helps.

      Not sure why it allowed you to create as bank key since this is indeed an invalid ABA number. Probably SAP internal alogritham failed to check this somehow. However I would suggest whenever creating bank key its good to refer Google as you will find most of the information relating to Bank Key, IBAN etc there.

    I have following values in our system and able to create bank master data. you may cross check your values with this.

    Bank Key 4 Assign externally

    Length Checking rule

    Bank account number 17 6 Maximum value length, numerical

    Bank number length 9 6 Maximum value length, numerical

    Post bank acct no. 10 6 Maximum value length, numerical

    Length of Bank Key 11

    • Hi,

      FIrst of all, I would suggest that you contact your bank to ensure you're getting the correct bank number.

      If you want to avoid this error, you can go to transaction OBA5 and customise this message AR 149 with '-' in online and batch.

      Otherwise to know the exact reason on why the check is failing, you could check the bank number in FM FI_CHECK_BANK_NUMBER_US which is used to validate bank data when you choose further checks option in

      OY17 settings.

      Hope this helps,

    I know it has been a long time and you probably wouldn't check this post but did you find out why was the system behaving that way?

    I am facing the same issue. I did a quick internet research and couldn't find the ABA routing number as well. My settings are exactly the same that you had then.

    A response will be much appreciated..
