Calculating whether to apply a usage estimate

You can calculate whether to apply an estimate setup to a meter reading using an Add On Condition formula. For example, you could write a formula that determines whether the previous readings are consistent enough to estimate a usage, or that indicates that a meter is within a certain category, such as a certain service area. You specify an Add On Condition formula for a usage estimate when you add or edit a usage estimate setup.

Add On condition formulas use the LocationHistory object (an instance of the Hansen.AssetManagement class), MeterReading object (an instance of the Hansen.AssetManagement.Water class), ServicePosition object (an instance of the Hansen.Billing class), and WaterMeter object (an instance of the Hansen.AssetManagement.Water class) to set AddOnCondition to either True or False. If the formula returns True, Infor Public Sector applies the usage estimate to a reading requesting an estimate. If the formula returns False, Infor Public Sector doesn't apply the estimate. For more information about this object and for sample code, click the Information tab in the Formula Editor.

Dim res as Hansen.Core.Result = Hansen.Core.Result.Success
res = oMeterReading.GetPreviousReading()
	if( res.IsSuccess)
bEstimate = FALSE
	else
bEstimate = TRUE
	end if
else
bEstimate = FALSE
	end if
