Bank Account Number in AX 2009

I am setting up the bank account number for an vendor (EFT) and I can only enter in 11 digits into the Bank account field. The maximum number of digits should be 12. Is there a way to change that?

Hello Rika,

Open the AOT by <CTRL+D>
Goto AOT\Data Dictionary\Extended Data Types\BankAccountId
click right mousebutton, choose properties.

There you will find a property called StringSize, change the length.

Save your changes within the AOT.

Dont forget to synchronise your database.
Set your focus on Data Dictionary, click your right mousebutton, choose menuitem synchronise.

Best regards,
