When you have finished with a task assignment, complete the task in the task list. Completing a task forwards the task to the next step in the workflow.
For example, you have a two-step workflow with a translate step and a review step that circles back to the translate step if rejected, or progresses to the Finish step if accepted.
When the translator finishes translating the task and clicks Complete, the task moves to the reviewer. When the reviewer finishes reviewing the task and clicks Complete, there is a choice to accept or reject the translation. If the translation is accepted, the task is finished. If the translation is rejected, the task circles back to the translator for corrections.
