Workflow System Elements in the Workflow Container Workflow System Elements in the Workflow Container
The workflow container holds some container elements as workflow system elements. You cannot edit these but you can use them. The workflow system assigns values to the workflow system elements as standard. Each work item or associated method can read these values if you have defined an appropriate binding from the workflow container to the task container.
To avoid naming conflicts, the workflow system elements begin with "_".

_WF_Initiator |
WFSYST-INITIATOR |
Initiator of the workflow (user name). The user name is a 14-character field in the structure US<Name> .If you started the workflow with Runtime Tools ® Start Workflow, your user name is in this element. If a workflow is started via an event, this container element does not initially have a value. However, the container element can be assigned a value via the binding from the event container of the triggering event. For this, the binding must be defined from the container element _Evt_Creator of the event container to the container element _WF_Initiator of the workflow container. |
