These calculations can be simple or complex, and they support the use of limits, weighting, and factor tables. Each asset health calculation can include multiple calculation variables. The result of an asset health calculation is an asset health index. Note: The APM calculation feature is very powerful and allows users to write code that executes on the server. As such, we strongly recommend using APM security profiles to secure access to the functionality as well as reviewing all calculation code. Each asset health report definition can contain a maximum of five asset health calculations. Within each calculation there can be multiple calculation variables. Asset health calculations can only be edited when they have the status “inactive”. Once a calculation active, it can be used in any asset health report definition. The steps involved in creating an asset health calculation are: • Create the asset health calculation • Create the asset health calculation variables, if needed • Define the factor table (numeric variables), if needed • Define limits and weighting (numeric variables), if needed • Define null value behavior, if needed • Define the calculation states • Test the calculation This topic describes in detail how to create an asset health calculation record and directs you to other related topics.
