Install Task Parenting


in v0.5


This script must be installed to enable parent and sub-tasks. Also defines "Prerequisites" and "Successors" columns.

How to Use

After this script is installed, the Shift Right and Shift Left comands are enabled in the Edit menu.

To directly assign a task to a parent, add the "Parent ID" and "ID" columns, and enter the ID of the parent task into the "Parent ID" column.

How It Works

Parents derive their start and end dates from their children. Parent dependencies are inherited by all of their children.


"Prerequisites" and "Successors" columns shouldn't be defined here. They are here because they were enabled by the same changes that made the "ChildTask" column possible.
