Defining the Variable Map Used by a PSP Procedure
Variable maps are used by the context service to create the property sets that are used by PSP Procedures. You specify the variable maps used by a PSP procedure in the Parameters list applet of the Administration - Order Management screen, then the Signals view.
The PSP procedure is independent of the calling context. Most order management signals invoke the PSP Driver Workflow Process (shown in the second figure in this topic), which is a generic controller workflow. The controller workflow uses variable maps to construct inputs for the PSP procedure. Those variable maps are defined in the signal that invokes the controller workflow.
Signal parameters define the scope of line items retrieved using the variable map, and they define the variable maps used to retrieve Context and Row Set data. The following figure shows example signal parameters.
