Workflow system variables in workflow containers and work item containers are entered by the workflow system using technical definition information and runtime information. These system variables can be identified by their names, which begin with "_".
From Release 4.0 onwards, some of these variables are no longer explicitly available. However, the information is still available as an attribute of the work item and can be accessed via expressions for container element _WORKITEM.
The following workflow container elements are involved:
_WF_System no longer exists
_WF_Client no longer exists
_WF_Org_Unit no longer exists
also under _Workitem.CreatedByUser.NameWithLeadingUS
_WF_Start_Date _Workitem. ActualStartDate
_WF_Start_Time _Workitem. ActualStartTime
Binding definitions which refer to elements which are no longer supported must be converted accordingly by customers.
