Environment
Web Applications "Reports --> Power Quality Report"

Cause

When the report is run the stored procedure "spPQ_GetConfigurationForIncident" is called which chooses the maximum value that exists in the entire datalog as opposed to the value that corresponds to the power quality event.

This is a known issue and is noted as SCR7140

Resolution

You can run an SQL query to manually set the Sag and Swell limits for a device in the database.

Always backup the databases before running any SQL query.

USE ION_Data

UPDATE DataLog2 SET Value = <current value>

WHERE QuantityID = <sag limit or swell limit>

AND SourceID = <your device ID>

Here,

The quantity ID is 275 for the sag limit and 276 for the swell limit
To change the sag limit to 90 as in the example above. Insert "90" in the DataLog2 field
And you can determine the device source ID by looking for the device in the "ION_Data" --> "Source" table.
