Use Renumber project lines to assign new, consecutive numbers to project lines, for example if line numbers have been modified manually, or if duplicate numbers exist after projects have been copied.

You can choose to renumber a project line including all underlying lines, or all projects.

Example

To renumber all phases and activities within a project, using a step size of 10, to create line numbers 10, 20, 30, etcetera, select 'Modify underlying lines' and fill in '10' as the step size.
