About the Product Selection and Pricing Engine

The Product Selection and Pricing (PSP) engine is a generalized procedural logic engine for transforming an input row set into an output row set. PSP is an extension of Siebel Workflow. A PSP procedure is a workflow process that includes a Business Service step employing methods of the Row Set Transformation Toolkit business service.

A PSP procedure transforms a set of input rows into a set of output rows by executing matrix lookups, conditional logic, and external function calls. In this release, the functions of pricing, eligibility (product, attribute, and promotion), and product recommendation use the PSP engine.

For example, Siebel Pricer uses PSP procedures to apply all of the different types of discounts that are available with a particular product. Because these discounts are based on a PSP procedure rather than on C++ code, you can:

• Change the order in which discounts are applied.

• Customize the calculations used by discounts.

• Extend the preconfigured pricing PSP procedure to calculate additional costs or prices and margin.
