 ## Setting a pipeline return value in the Set Variable activity with UI
 
 The Set Variable activity now allows you to set a pipeline return value (preview). The pipeline return value is a system variable that allows you to customize a value that can be consumed by a parent pipeline and used downstream in your pipeline.

 ## Incrementing a variable
 
-A common scenario involving variables is using a variable as an iterator within an until or foreach activity. In a set variable activity, you cannot reference the variable being set in the `value` field. To work around this limitation, set a temporary variable and then create a second set variable activity. The second set variable activity sets the value of the iterator to the temporary variable.
