About User Tasks
User tasks are tasks completed by a human within the scope of the process, and call a webMethods task to provide the interface. They are configured on the pages of the Properties view. Previously existing webMethods tasks (not the same as BPMN task activities) become new user tasks when you open the process in Designer 8.2 or later.
For more information about working with tasks, see webMethods BPM Task Development Help.
