Defining a Business Entity Function
The function of a business entity can perform any action that is defined in its body, such as to perform a calculation, execute an SQL query, assign a value to a property, or sort a list. Some functions return a value.
The function of a business entity is activated when one of its events triggers it. See Defining a Business Entity Type Event for a description of how to define an event that triggers this function. A business entity's function can also be triggered when you define a business rule or an event handler.
A business entity can activate itself. All other Real-Time Designer objects must be activated by another object, such as a rule.
