The user context taken by expressions (and certain logic executed behind-the-scenes) can encounter user-rights issues when the system is attempting to derive information at runtime. For example: if a process is initiated by a certain user who does not have sufficient rights to access a resource requested by an activity input, that activity may encounter an exception that halts process execution.

• When an activity is run in unattended mode, you have the option of using the user context of the process designer or the process initiator.
• If the activity is attended, you can opt to run the activity in a subprocess that takes its user context from the parent process designer.

The following contexts are used for derived items.

Evaluated Logic	User Context
Node name	Initiator
Node deadline	Attended: initiator Unattended: initiator or designer (as configured)
Node paused by exception notification	Attended: initiator Unattended: initiator or designer (as configured)
Form element	Initiator
Form element refresh	If non-SAIL form, initiator; if interface, task owner if accepted, otherwise current task viewer
Activity input	Attended: If non-SAIL form, initiator; if interface, task owner if accepted, otherwise current task viewer Unattended: initiator or designer (It takes the configured context for primary activities. The programmed smart service context is used for other activities.)
Activity input refresh	Attended: If non-SAIL form, task owner if accepted, otherwise initiator (first time task is clicked on, it's initiator); If interface, task owner if accepted, otherwise current task viewer Unattended: initiator or designer (as configured) Note: If you re-run the expression as task owner and an error occurs, the existing value (run as Initiator) remains.
Activity output	Attended: task owner Unattended: initiator or designer (as configured)
Gateway condition	Initiator
Parallel spawned node output behavior	Initiator
Number of node instances to spawn	Initiator
Receive message output expression	Initiator
Receive message filtering	Initiator
Timer absolute start time	Initiator
Timer relative start time	Initiator
Timer filtering	Initiator
Timer timezone configuration	Initiator
Timer recurrence configuration	Initiator
Timer recurrence end time	Initiator
Timer recurrence end condition	Initiator
Process paused by exception notification	Initiator
Process name	Initiator
Process deadline	Initiator
Process variable defined using an expression	Initiator
Rule evaluation	Initiator
Message start event process variable evaluation	UserName property from message
Timer start event process variable evaluation	Process model owner. If null, then designer.
