DD.2.2.6 Update GP-SPS (IN PROGRESS)

The Performing Device updates a General Purpose Scheduled Procedure Step (GP-SPS) managed by the Workflow Manager to have the status IN PROGRESS upon starting work on the item. The SOP Instance UID of the GP-SPS will normally have been obtained via the Receive GP-SPS message as a worklist item. This message is conveyed using the N-ACTION primitive of the General Purpose Scheduled Procedure Step SOP Class with an action type “Request GP-SPS Status Modification”. This message allows the Workflow Manager to update its worklist and permits other Performing Devices to detect that the GP-SPS is already being worked on.
