Image of the I-Web Work Items page.  A circle and arrow indicate a parent record in the task list.  A circle near the bottom of the page indicates the cost block.

When a parent record in the Tasks block is selected, the system displays the applicable child record in the Costs block.

This is the cost record (also called line number) for this task. When you use the Basic or Complex tab to add tasks, each task has only one cost record. Legacy tasks do not have any cost records.
