In earlier releases, Siebel order management functions and function calls were handled locally by the code in the calling object or business component. In this release, every interaction between C/OM components occurs through an API invocation that you can configure or redirect. These API invocations are called signals. A signal is a request to perform a business function.
Each API invocation supports a configurable set of input arguments. The API is handled by a series of business service methods and workflows that you define in the Administration - Order Management > Signals views.
