Rule-Declare-DecisionTable (Part 1)

Decision Table is used to provide an output from one of the several possible outcomes.

Each possible outcome is based on a certain condition/ value of a property or a set of properties.

Can be referenced from one of the several possible PEGA rules:

1.       Flow à Rule-Obj-Flow

2.       Activity à Rule-Obj-Activity

3.       Declare Expression à Rule-Declare-Expressions

Various buttons to add/delete a row/column in the Decision Table.

When we have multiple columns, then each column’s value will be evaluated before returning the value from the RETURN column.

Each row in the decision table acts as an if condition. When one if fails, then the next else if row, with multiple/single column condition will evaluated before giving the result.
