A Controller Workflow Invokes the PSP Waterfall Business Service

The following figure shows how the PSP Waterfall mechanism generates and saves waterfall output.

  • For a PSP procedure that generates waterfall output, such as the Pricing PSP procedure shown in the diagram, a controller workflow invokes the PSP waterfall business service.

  • The PSP engine supports the creation of a waterfall with an unlimited number of sequenced child rows to explain each name-value pair in the row. It is the child rows’ type that defines the waterfall to which they belong.

    For example, “Net Price Waterfall” is the type for each of the child rows that compose the Net Price waterfall. Multiple waterfalls can be created for one row, up to one for each name-value pair.

  • Each waterfall has a configurable set of name-value pairs. For example, a pricing waterfall uses different fields than an eligibility waterfall.
