When you create a process that consists of a series of components, the components are executed in order from left to right (Capture to Route). Each component, prior to its termination, searches all configuration entries and replaces all its own RRTs with actual metadata values. As an example, the XML Knowledge Package Loader component will search for RRTs starting with ~ASX:: and replaces them with actual metadata values.
The order of execution of components within a process is significant. Due to the component execution order (Capture to Route), RRTs owned by components that appear later in a process cannot be placed within components that appear earlier in a process. As an example, placement of Folder Store component RRTs within a Capture component such as Poll Directory is invalid and will not be replaced at run time.
