Is there a way to re-open the approved timesheet created using project timesheet workflow?

Hi,

Environment: AX 2012 R3.

We have created a workflow for project timesheet.  Workflow is setup. Worker has submitted the timesheet  and manager has approved it. Timesheet is then posted.

Is there a way to re-open the time sheet which is posted?

Is there a way to re-open the timesheet which is approved but not posted?

Any help will be greatly appreciated.

Thanks,

Nadeem
