End date Supplier Bank Account

Hi,

I need to End date a Supplier Bank account from bank Account level screen, after click on the update button of the Bank account.

But once I give an end date and click on save following error appears.

'The external bank account already exists'

This is account is created in another two sites for the same supplier. The account should be end dated in the other sites as well.

Please be kind enough to give the steps to end date the account in every site for the same supplier account.

Thank you
