Issue
The Energy Cost Report does not show any data for a source that is known to have the required data. Running another report, such as a Trend Report, shows the desired energy data.

Cause
The Energy Cost report looks for specific measurements in a specific order, as defined in the CFG_ItemValue table in the ION_Network database (see FA214149 for a full listing of measurements). It uses the Channel table entries in the ION_Data database to determine which measurement to use for a given source. If a device has had configuration changes such that more than one measurement from the CFG_ItemValue list appears in the Channel table, the Energy Cost report will automatically choose the measurement from the Channel table that appears first in the CFG_ItemValue list, even if this measurement is not the one that has data for the device in the chosen time range.
So if the Energy Cost report is run for a device but returns no data, and you are sure there is energy data for the device, check the Channel table in ION_Data. You can use this query:
USE ION_Data
SELECT * FROM channel WHERE recorderID IN (SELECT ID FROM Recorder WHERE SourceID IN (SELECT ID FROM source WHERE name = '<your device name>'))
This query will produce a column for the device called "IsCurrentConfiguration".
Resolution
*Warning: Irreparable database damage can occur. This procedure should only be performed by users familiar with SQL Server Management Studio. Databases should be backed up prior to performing this procedure.*
There are a couple of workarounds:
1. Delete the old entries from the Channel table - this is the approach to take if there is no data in the database for these measurements for this source.
USE ION_Data
DELETE FROM channel WHERE recorderID IN (SELECT ID FROM Recorder WHERE SourceID IN (SELECT ID FROM source WHERE name = '<your device name>')) AND IsCurrentConfiguration = 0
2. If there is data then edit the CFG_ItemValue table to modify the order that the measurements are listed. Note that doing this affects all Energy Cost reports run against all devices. The order of measurements in ION_Networkcan be changed by running the following query.
USE ION_Network
-- this will put Active Energy Delivered to the front of the list so it will get used.
UPDATE vCFG_ConfigItems
SET VALUE =
'Active Energy Delivered·Active Energy Delivered+Received·Active Energy Delivered-Received·Active Energy Delivered Rate A·Active Energy Received Rate A·Active Energy Delivered Interval·Active Energy Received Interval'
WHERE Item ='EnergyCost_kWh'
