Assign External bank account only to supplier site - iby_ext_bankacct_pub.create_ext_bank_acct

Hi ,

I am using iby_ext_bankacct_pub.create_ext_bank_acct to create external bank accounts.

After creating the external bank account , I am using  iby_disbursement_setup_pub.set_payee_instr_assignment to assign the account to supplier sites.

But the process of creating external bank account assigns it to the supplier and the account is visible under supplier banks.

I need to assign the account only to supplier site and not supplier.

Thanks in advance,
