[Method] outputs the running metrics of workflow to target, and workflowtarget

Take the output workflow start time as an example:

First, create the workflow-level variable $ test (datetype: date/time) in workflow)

Next, double-click the link after Start and assign starttime to the newly defined wk variable $ test.

Return to the Designer and add the mapping-level variable $ test (datetype: date/time) to the mapping)

Return to Workflow Manager, double-click mapping's session-> component-> pre-session variable assignment, and assign the workflow variable value to the mapping variable.

Return to Designer and assign the mapping variable value to a column in expression.
