Send Req approval notification to group of approvers

Hi,

We have a requirement to notify 3 requisition approvers when requisition created. If one approver approved the req#, other 2 notifications to be closed. We don't want to move to AME and we would like to achieve this using the workflow approval process. To achieve this, we created new role and attached all 3 approving users to it. This role has been defaulted as constant in the notification performer and enabled the Expand Roles. This works fine. But, in the group of users only one approving user can able to edit the requisition using "Edit Requisition" link. Others 2 users
