System Workflow Variables

System workflow variables return system run-time information.
You cannot create system workflow variables. The Developer tool provides a pre-defined list of system workflow variables that you can use in a workflow.
Use a system workflow variable in a conditional sequence flow or in a task field so that the Data Integration Service uses the variable value at run time. For example, use the UserName system variable in the list of recipients for the Notification task to send an email to the user that runs the workflow.
The following table describes the system workflow variables:
System Variable
Datatype
Description
InstanceID
String
Unique ID of the workflow instance.
StartTime
Date
Date and time that the workflow instance starts running.
UserName
String
Name of the user that runs the workflow instance.
