Business Knowledge Model Decision Table

A decision table is a tabular representation of a set of related input and output expressions, organized into rules indicating which output entry applies to a specific set of input entries.

Figure 1.  Business Knowledge Model (BKM) implemented as Decision Table 

Open the BKM in DMN Expression view. 

The BKM defines two parameters, and the body is implemented as a Decision Table ('Unique' as the hit policy), which defines two Input Clauses, one Output Clause and eight rules.

Simulation
Switch to the "Input Parameter Values for Simulation" tab and provide values for the parameters:

Validate and Run. The results will be rendered on the Decision Table.

The runtime values for the Input and Output Expressions will be rendered in the "allowed values" row and the matching rule will be highlighted.
