TimeLine Columns

Reference for the standard TimeLine columns and how each column is used by the Gantt chart and calculation engine.

TimeLine stores the schedule in normal table columns. The Gantt chart reads the mapped columns and writes calculated results back where the file supports them.

Main planning columns:

  • Task ID is the stable task number used by predecessors. When mapped, it mirrors the row ID and is normally read-only.
  • Task Name is the label shown in the table and, when enabled, beside the activity in the chart.
  • Start Date is either typed by the user or calculated from predecessors.
  • End Date is calculated from the start date, duration, task type, calendar, and dependencies.
  • Duration is the working duration for normal duration tasks. It can also be calculated when the task uses productivity mode.
  • Calendar chooses the working calendar used for that task.
  • Predecessor stores dependency expressions such as 1FS, 1FS+2d, or 3SS.
  • Task Type controls whether a row is a Duration task, Productivity task, or Milestone.
  • Progress stores completion percentage and can be shown as progress fill on the activity.

Extended planning columns:

  • Productivity and Quantity let TimeLine calculate duration from production data.
  • Description, Priority, Tags, Documents, and People support coordination with other WorkStudio planning surfaces.

Rows can also act as WBS phase or summary rows. In that case, the chart draws a summary activity and derives dates from the child rows under that WBS level.
