Activities are the major actions undertaken by personnel. Subactivities (sometimes called function codes), are more detailed actions that are associated with activities. Work activities use a two-level hierarchical arrangement that allows you to create activities and subactivites and also associate the subactivities with a particular activity.

The System module provides three windows for activities and subactivities:

• Activities: Use this window to create and maintain activities
• Subactivity: Use this window to create and maintain subactivities
• Activities-Subactivities: Use this window to associate subactivities with a particular activity
