ProcessFlow Job Requisition Approvals
After a job requisition is in the ProcessFlow approval process if you make a change to the Job Requisition (PA42) your WorkUnit is cancelled by the system and a new one is kicked off. This restarts your flow at the beginning of the approval process and may not be the way you want to go.
One way around this is to use your initial JobReq Approval Service to kick off a new service (using a WorkObject in your flow) which will then handle the approval process of the Job Requisition.
The down side is that a WorkUnit will still be created when a change is made to your Job Requisition but you can design your flow to check whether or not the 2nd service was already kicked off and simply go to the End of your flow when true.
