What if you have been assigned a workflow task, but you feel you are not the appropriate person to complete it? No worry, you can assign the task to another person.
When you reassign a task, it will show you all the possible users in the drop down. The list is generated dynamically and it depends on the roles assigned to that particular step.
After you reassign the task, the new assignee will see the task in their inbox and will also receive an e-mail notification . Also, more importantly, the Workflow history will capture this particular action.
If you intend to hide the “reassign” functionality, you can simply remove the “ow_reassign_task” capability from that role.
