• Create a new line item type concept (with breakdown or lift), from the "Create new concept" option.

To locate a work section or a line, simply click on the "Search work section or item" button (4) on the toolbar in the chapters area. From the "Search for work section or item" dialogue box that appears, users can search for the item by:

  By typing the complete words or only an initial part of them separated by spaces.
