When an action is triggered (Submit/Approve/Deny/etc) a transaction document is created of the appropriate 'type'. The AC Process Action Agent then processes the transaction. This done so the end user never needs more than Author access to the database and never needs to edit the request document (except as the creator). If there is no chance of more than one person being able to modify a document at the same time then Process Immediately can be set to Yes, otherwise it MUST be set to No or else there is a high probability of Save/Replication Conflicts that will be very difficult to resolve. Problem Situations: If a document is routed in a parallel process. All people in the Approvers List are possibly active Approvers at the same time. When replica copies of the database reside on more than one server, then the AC Process Action Agent must be set to run on only one of the replica servers and Process Immediately must be set to No. In some cases when there are a lot of notifications to be sent and/or there are numerous other actions that might be taken, you may want to set Process Immediately to No so that control is returned to the end user quicker.
