We use action groups to execute multiple actions based on the same set of conditions. Action groups make the maintenance of workflows easier because the conditions and other settings of multiple actions in the group are entered and updated at one time on the parent group.
To use action groups, create an action group, define conditions for the action group, and add actions within the group. You can only create action groups for actions that execute on a server trigger, including Entry, Exit, and Scheduled. You cannot use actions that execute on a client trigger.
To execute actions on Items sublist lines, use sublist action groups.
A Sublist Action Group is a group of actions assigned to a workflow state that is to be executed on each line of a sublist. Whether the actions execute during a workflow state is contingent on the group’s and group actions’ conditions. The sublist action group’s condition determine if the group executes.
