  • What is the different between L1, L2 and L3 tasks?
L1 (Level 1) and L2 (Level 2) are summary tasks.  This means that they do not contain any information of their own.  They are merely a summary task grouping.  These tasks automatically inherit their time related properties from level 3 tasks.    Consider L1 and L2 as merely logical groupings of activities.
