Journal Approval Workflow - Different status's
I am looking into implementing Journal Approval Workflow. Peoplebooks is a bit vague. I don't understand what the 'Pushback' button is used for and the 'Hold' button. When would you want to do either one ? I 'think' the Pushback is if you have many approvers and want the approval to go to the previous approver , is that correct ? but wouldn't apply if you only had one set of approvers ? The 'Hold' I don't know either. Thanks in advance.
