Process Interfaces See "Process Interfaces" in TIBCO Business Studio Concepts. Optionally, you can create a process interface with one or more message events This creates an abstract WSDL file that is stored in a folder named Generated Services: You can then call this abstract WSDL file in a service task, or optionally add the concrete implementation details to the WSDL file. Using the Process Interface Editor, you can modify the interface to add events or parameters: Once created, a process interface can be used by several different processes. If a process is created using a process interface, all the events and parameters specified in the interface must be present in a process that implements that interface. You can add additional events or parameters, but removing any of those required by the process interface will invalidate the process. If you have additional parameters that are local to a process that implements a process interface, you can move the parameters into the process interface by right-clicking the parameter and selecting Move Parameter to Interface: This option is only available for processes that implement a process interface in the same package, and only for parameters that do not have problems in the Problems view. If you create a process using a process interface, the process that you create inherits the events and parameters created in the interface. For example, a message event in a process created using a process interface displays the following properties: If you cannot see the right-hand side of the following dialog, switch to the Solution Design capability using the following menu or click Provide Implementation Details.
