How I can auto approve pending workflow process, once month end proces

Question

I have created workflow process for timesheet approval.
I want to auto approve all pending timesheet (i.e (default notification timeout is 7 days) notification send to approver, but still not approved) in Oracle workflow Process, when Month end process started
Month end process will initiate a flag in pending timesheet header table with process started

Answer 1

I am not sure if I understand your requirements completely.
1) If your requirement is that all the pending timsheets have to be approved by month-end (not really when month-end process starts) then set the Timeout of the notification to Absolute Time of end of that month... so that by the end of the month the background engine will pick it up.
You may design the approval notification within a Sub-process with RESULT attribute of Approve / Reject. Design a Timeout transition for the Notification Activity within the sub-process that will go to an END activity that has Approve result. Thus once the notification times out, the sub-process will complete with result APPROVED.
2) One other way is to respond to OPEN notifications using APIs.
WF_NOTIFICATION.SetAttrText(nid, 'RESPOND', 'APPROVED');
WF_NOTIFICATION.Respond(nid);
You should have queried up all OPEN notifications for Timesheet approval and do this in a loop... which could be time-consuming sometimes.
