I am attempting to evaluate an expression similar to:
string expression = @"'XYZ\Fields\eeeee|Total Gas' + 'XYZ\Fields\dddddd|Total Gas'"; afValues = AFCalculation.CalculateAtIntervals(db, expression, timeRange, new AFTimeSpan(TimeSpan.FromMinutes(30)));
And I get the error:
Expressions do not support PI Points whose UOM configuration differs from its attribute's in Attribute
Is there any parameters or other suitable API methods that will allow me to evaluate this expression.
