You must define a top level process for each task flow. The top level process can contain sub processes, but not any other top level processes.

A top level process must have a Top Node Selector activity. This ensures that the first window in a task flow is a valid top node window. All windows that can be a top node are defined within the Top Node HRMS Context Windows lookup type.

The Top Node Selector must have two transitions. The first transition must go to the Top Node activity and its value must be the window activity name. The second transition must be <Default> and go to the end activity.

You use the Process Diagrammers within Oracle Workflow to create your task flows. You do this by adding and connecting the windows you want to appear.

   To create a top level process:

1. Enter a unique internal and display name for the new process for the HR Task flow item type.

   Suggestion: Use a naming convention for Internal and Display names. For example, a good internal name might be POSITION_DETAILS_TL with a Display name of Position Details (Top Level).

2. Define the process as runnable.

3. Open the Process Diagrammer window and add one Start activity and at least one End activity.

4. Add a Top Node Selector activity. The Start activity must connect to the Top Node Selector activity.

5. Connect the Top Node Selector to the End activity with a <Default> transition result value.

6. Add the Top Node window.

7. Connect the Top Node Selector to the Top Node window, specifying the name of this window activity as the transition result value.

8. Connect the Top Node window to the End Activity with a <Default> transition result value.

9. Add other windows to the process, noting the following rules:

   • A window can only connect to another window where the result type is the same (such as, both Person Context windows).

   • The transition result value must be the name of the window activity you are connecting to (for example, F4 Enter Assignment).

   • Each window can only connect once to any other window.

   • Each window must be connected to the Top Node window with a <Default> transition result value.

   • You can connect a window back to its parent using the <Parent> transition result value, rather than the name of the parent window.
