A controller workflow is the invocation mechanism for each PSP procedure. The workflow called PSP Driver Workflow Process is the default controller workflow. When a signal calls the controlling workflow for a process, it passes the names of the PSP procedures to the PSP Driver Workflow.
NOTE: PSP Driver Workflow is the default controller workflow, but you can configure your own controller workflow to replace the default if you find that modifications are necessary for your organization's requirements. You configure a controller workflow in the same way that you configure a standard workflow process. You specify the arguments of a controller workflow in the signal definition, so for your custom controller workflow, navigate to the Administration - Order Management screen, then the Signals view in order to change this definition. For information about configuring workflow processes, see Siebel Business Process Framework: Workflow Guide.
Arguments for the default PSP Driver Workflow are shown in Figure 18. PSP Driver Workflow is set as the controller workflow for the signal CalculatePriceAll in the Service Name field of the Actions tab.
The PSP Driver Workflow acts as the controller workflow for the pricing and eligibility PSP procedures. It calls the Context Service to construct a property set called Row Set containing the selected rows from the source object (Quote, Order, Agreement, or Customizable Product). It also calls the Context Service to construct a property set called Context that contains header-level information shared by all rows (for example: Account Type, Credit Score). It then invokes the PSP procedure specified in its input arguments. The PSP procedure updates and returns a new version of Row Set. Finally, the controller workflow instructs the Context Service to save any changes in Row Set back to the source object.
The PSP Driver Workflow, shown in Figure 19, does the following:
Table 11 provides a list of the steps in the PSP Driver Workflow Process, showing also the business service and method called by each step.
