Data

This command structures the data of a Decision Table. The data part of the table must be encapsulated by Row and then by Value element in the xml. Each value in the data section represents a positive condition, if a negative condition is required it should be prefixed by ‘not:’.

Decision Table supports iterating through items of a list and processes them. To do that, the on and childName parameter must be set.

Parameters

  1. on
    1. Description: Defines a list of items to iterate through
    2. Mandatory: No
    3. Type: Expression
  2. childName
    1. Description: Defines the name of parameter, each item in the list will be referenced
    2. Mandatory: Yes, when ‘on’ is defined
    3. Type: String (Parameter name)
