Hii Experts, I have a scenario where need to complete the Workflow User Tasks with scheduled event.  A schedule event will be run which check if task is due, if yes then it should get completed and continues workflow. But I am getting an error while completing the task and it is as "Task can be completed only by the named user". please suggest the solution or any work around I can do.

In Community Commons, you’ll find three Java actions to execute a microflow as a particular user.  I think using one of those could enable you to do this.
