Business Tasks can be manually or automatically locked in ActiveControl to prevent more transport forms from being attached to them. One common use case of Business Task locking is when the SAP change is ready for production, so that no further transports can be attached to it at the last minute.
Business Tasks can be locked manually in the Web UI or in the Windows GUI.
