Creating Dynamic Sub-Processes

A dynamic sub-process can be created by modifying a call sub-process activity.

1. Create a process interface that specifies the start event and its input/output parameters. Each process that is to be invoked from the dynamic sub-process task must implement the same process interface. See See "Process Interfaces" in TIBCO Business Studio Concepts..
2. Create one or more call sub-process activities in your process.
3. From the General tab for each call sub-process activity:
   1. Using the picker, select the process interface created in step 1.
   2. In the Runtime Identifier Field select a formal parameter or data field using the picker. This must be a text field or an array. Arrays can be used for multi-instance sub-process tasks where potentially different sub-processes are required for each instance of the same task.
      
4. Initialize the Runtime Identifier Field. For example, for a multi-instance sub-process task you could create a Script task before it to populate the array data field with a sub-process name element for each task instance. For a single instance sub-process task simply set the runtime identifier field to the required sub-process name in a script prior to the task.

   For a sub-process implementation which resides in an external sub-process library., you could use a script something like the script shown in the following illustration:

   
5. In the call sub-process activity, map data to and from the called process (to pass data between the process and sub-process):
   • Map the input to the interface in Map To Sub-Process.
   • Map the output from the interface in Map From Sub-Process.

     For example:
