Environment

Microsoft SQL Server Management Studio

Cause

The device to which data is being assigned already has existing entries for the specific time stamps included in the script. This may happen due to an overlap in time between disabling and enabling the two devices that data is being transferred between. In the following example the error is seen when trying to insert data to the source in the first column from 1/28/2025 8:15:00 AM onwards.

Resolution

Be sure to take an updated backup of the ION_Data database before making these changes

Remove the existing data, which is unwanted and intended to be replaced by using the following scripts, use desired SourceID (verify from [ION_Data].[dbo].[Source]) and TimestampUTC based on the system.

DELETE FROM [ION_Data].[dbo].[DataLog2] where SourceID = 9 and QuantityID = 69 and TimestampUTC > '2022-09-14' and TimestampUTC <  '2022-09-15'
