Each work item carries the two container elements _WI_Object_ID and _WI_Group_ID in its container. Both elements have been defined to hold an object reference.

• The container element _WI_Object_ID automatically contains the reference to the object to be processed in the work item
• The container element _WI_Group_ID can contain an object reference, which must be assigned to this container element in a binding or via initial value assignment.

The object reference assigned via _WI_Group_ID is generally not identical to _WI_Object_ID , but is derived from the work item execution environment. It is used to group work items that refer to different objects or object types but are nevertheless connected.

The default attributes of the objects referenced in _WI_Object_ID and _WI_Group_ID are available in the Business Workplace's workflow inbox under the column headers Object or Group for grouping, sorting and filtering purposes.

The default method of the objects referenced in _WI_Object_ID and _WI_Group_ID is executed by double-clicking in the Object or Group column.
