Product Line:

Environment:
Power Monitoring Expert 7.2.2 Web Applications - Reporting

Cause:
There is a known issue when upgrading from PME 7.2.1 to PME 7.2.2 that causes duplicate entries in the dbo.TS_Triplets table in the ION_Network database. These duplicate entries prevent the measurement selector from querying the necessary measurements.

Resolution:
