If an offer has approvals on it, the other approvers on the approval chain and the person who requested approval will be notified.
Under Offer Details you can click on 'Update' and edit the offer. If a field is edited that will retrigger approvals (noted by a small check mark), it will create a new offer version. You can then Request Approval on this new offer version.
