Each class in a COM Proxy has a unique set of properties based upon its procedure step import and export attributes. The import properties are read and write properties, whereas the export properties are read only. The name of each of these properties is the combination of the attribute's entity view name with its entity name and attribute names. The attribute's domain, length, decimal place value, and precision flag determine the type of these properties. See the following table:
