Payroll Bank Account visible in OU

Hello Gurus,We have added a new OU under a existing Business Group,In cash management we are not able to see any other bank accounts of other operating Units, but one bank account which is used for payroll was visible in the cash management responsibilty of new OU created.Ideally Business does not want to see this Bank account(Payroll) in the cash management Responsibility of newly Created OU.Is there any way to restrict this Bank account not to be seen in the LOV of ' Bank Statement Interface' 'Bank Statement Interface and Reconcilation' Form.RegardsRebecca
