Meter Read Estimation Trend Class Segmentation
When you set up a metered SP type, you must define the consumption estimation trend class in which its consumption will be categorized. This categorization matters when consumption differs based on the type of property AND you want the system to estimate consumption in different classes differently.
These categories could be the classic divisions of residential versus commercial versus industrial consumers. Alternatively, they could be finer-grained divisions: single family residence, versus duplex, versus triplex, versus medical office, versus grocery store.
Refer to The Theory Behind Consumption Estimation for more information about how trend class is used to estimate consumption.
If we assume you differentiate between residential and commercial service for all of your metered services, then your SP types will be:

Notice that the non-metered service points don't use a trend class. This is because they don't have meters (and only meters have estimated consumption).
