Reproducing the Issue

  1. Go to Payables Work center.
  2. Go to Supplier View.
  3. Select Supplier and Click on Edit.
  4. Go to Financial Data and Choose Bank Data sub tab.
  5. Add two different bank accounts with same IBAN where the first Bank Account is delimited.

When trying to add a row you receive the error Same IBAN is maintained for different bank accounts.


Currently, there is a constraint and is not possible to maintain the same IBAN for different bank instances.

(instance here means two records for the bank directory entry, that you maintain under Liquidity Management - Master Data> Bank Directory).


  • To remove/delete the bank entry from the supplier and create the new line. For the Audit reasons, in the change history, this change will be visible. So this will suffice audit requirement.
  • Also, would it be an option to use the same instance of the bank directory entry just giving it the new details (like name etc.).
