Hello IIke, ope option is what friend Karthik comment trough old DSWP.
Another old one is trough DSSESS transaction where you can list all sessions on solution manager, ewa and service sessions.
On Solution Manager 7.1 you also have different options:
1.- Go to "System Monitoring" Work Center -> "Reports" -> "SAP Early Watch"
2.- Go to "SAP Engagement and service delivery" -> Reportsa" -> "Early Watch"
Regards,
