PowerShell script to update Task "Outcome" and "% Complete" fields

Question

I have a problem (see Workflows do not continue after user completes a task nor do they update task outcome and percentage) that I can't get around. I thought about running a powershell script every night to work around it.

It would look for all workflows in a site collection and if their Task Status is = "Completed" it will update the Outcome and also % Complete fields.

I'm hoping that 'unsticks' my workflows.

Can someone point me to a PowerShell script that would do this?

Answer 1

you can try with following script,

 $list=$spweb.Lists["workflow list name"]
Foreach ($item in $list.Items) 
{
   $workflows = $item.workflows
   Foreach ($workflow in $workflows)
  {
    $tasks = $workflow.Tasks
    Foreach ($task in $tasks)
   {

    //Add your logic to update task property

    $task.Systemupdate()
}
}  
}
