Business Knowledge Model

Use a Business Knowledge Model to reuse pieces of decision logic — for example, a business rule, a decision table, or an analytic model.

A Business Knowledge Model can contain one or more Decision elements.

Decisions that have the same logic but depend on different sub-inputs or sub-decisions use Business Knowledge Models to determine which procedure to follow.
