Sub Types will only go against Task Groupings that are applicable to them.
For example, most Sub Types will be against the standard Pre Check group. However, if a Mudskip requires certain checks that other Units do not require when checking the Roof & Door Area, there would be two groups; a standard Roof & Door Area group and a Roof & Door Area (Mud Skip) group.


Creating these two Task Groupings means that when users perform a Checklist for a Mini Container for example, it would take over the Tasks from the standard Roof & Door Area group and when users perform a Checklist for the Mud Skip, it would take over the Tasks from the Mud Skip specific Roof & Door Area group.
When there is both a standard and Sub Type Specific Grouping, it is important to make the Group Order numbers the same. If the Roof & Door Area has its Order Number as 2, and Mud Skip specific group has its Order Number as 3, and users create a Checklist for a Mud Skip, it would not have a number 2 Task Grouping making it look like it has skipped a number.
