On the task details page of the flow view, you can click the More icon on the right of a step, and then click an action in the list that appears.

Note
On the task details page, the flow view shows the sequence of different steps in a flowchart. Drag the pointer in an empty area to move the flowchart. Scroll to zoom in and out. You can also use the zoom control in the upper-right corner to adjust the canvas size. The center of zooming is the pointer. For a long task, you can first zoom out, locate the node of interest, and then zoom in from there.
Expand the menu to display the log information in the lower part of the screen. You can drag edges of a window to expand it.
For failed steps, you can perform the following operations:
View the logs.
Rerun: Rerun the step. The operation will be first rolled back, and then performed again. If the operation is successful, subsequent steps are performed.
Set to Successful: After you set the status of a failed step to successful, subsequent steps are performed.
For steps that are running, you can view the logs or terminate them. After you terminate a running step, its status becomes failed.
For steps that are waiting to be performed, you can do nothing.
