Understanding Service Order Field Activity Types
A single service order field activity type must be configured to support communication with external field work systems such as Oracle Utilities Module Workforce Management. Service order activity types are assigned to the “Field Activity” Activity Type Category.
Refer to Understanding Activity Types for more information about activity types.
Service Order Field Activity Types and Divisions
Service order field activity types can specify a Division, to represent the specific operating company associated with activities of that type. If the Restrict Division setting in the Control by Division section in the MDM Master Configuration is set to "Yes", users can only access service order activities or service order field activities with a Division (or Divisions) associated with the user on the User Miscellaneous Information zone on theMiscellaneous tab of the User portal. 
See Understanding Divisions  for more information about divisions.
