Symptom
The reconstruction for notifications (quality/maintenance/service notifications) does not return any data for the BW extraction or in the relevant QMIS info structures. However, the relevant notifications do exist in the system.

Other terms
2LIS_05_Q0NOTIF, 2LIS_17_I0NOTIF, 2LIS_18_I0NOTIF, MC05Q00NTF, MC17I00NTF, MC18I00NTF, OLIQBW, OLIIBW, OLISBW, reconstruction, RMCQNEBW, RMCINEBW, RMCSNEBW.

Reason and Prerequisites
When you used transaction SPRO to create notification types, no update group was defined for updating the statistics. The STAFO field in the TQ80 table is empty. This means 'no update' for LIS and BW.

Solution
Use the Customizing of the notification type to create the relevant update group: Transaction SPRO -> SAP Reference IMG -> ... -> Notifications -> Notification Creation -> Notification Type -> Define Notification Type
