NOTE: The Current Value retrieval mode ignores the start and end times. If you want to return the most current value within the start and end time range (that is, the value closest to the end time), select the "raw" retrieval mode, set the Max. Rows at 1, and choose a Sort Order of Descending.
On the Edit Source/Configure New Object dialog box, select the Options tab.
Select Current Value from the Retrieval Mode drop-down list.
