Environment
EPSS Report Generator Performance Configuration Tool

Cause
This can happen if Generator groups have the EPS_Available option selected. When the EPS_Available and the EPS_RUN measurement have the exact same timestamp in the database, the 'Refresh run history' button cannot populate the rung history as it can't gather information on that group.

Resolution
To fix this issue find the duplicate timestamps, and change the EPS_Available quantity to be slightly different. For example make the EPS_Available timestamp 1 second after the EPS_RUN measurement. The SQL query below will reveal the duplicate timestamps. Keep in mind that running this query on a large database could take a while to finish. This query will give a list of sources in the database with duplicate timestamps. From that list, one of the duplicate timestamps must be changed as described above.

USE ION_Data
SELECT * FROM
(

SELECT COUNT (*) AS duplicate, sourceID, TimestampUTC FROM datalog2

WHERE QuantityID IN (10950,11148)

GROUP BY SourceID, TimestampUTC

) AS Q

WHERE duplicate > 1

Once there are no longer duplicates, the run history will populate as expected.

To get rid of duplicates run the below script for each timestamp:

BEGIN TRANSACTION;

BEGIN TRY

USE ION_Data

DECLARE @Temp as DATETIME2 = '24-06-24 19:32:00.0000000' -- replace with timestamp from the script above

UPDATE Dbo.datalog2

SET @Temp = TimestampUTC = DATEADD(s,1,@Temp) -- increments EPS available by 1 second

where SourceID = 4 and QuantityID = 10832 and TimestampUTC = @Temp -- replace quantityID with the EPS available quatityID and the Source ID with the sourceID from the above script's output

END TRY

BEGIN CATCH

SELECT

ERROR_NUMBER() AS ErrorNumber,

ERROR_SEVERITY() AS ErrorSeverity,

ERROR_STATE() AS ErrorState,

ERROR_PROCEDURE() AS ErrorProcedure,

ERROR_LINE() AS ErrorLine,

ERROR_MESSAGE() AS ErrorMessage;

IF @@TRANCOUNT >0

ROLLBACK TRANSACTION;

END CATCH;

IF @@TRANCOUNT > 0

COMMIT TRANSACTION;
