This is a dynamic masking dataset that applies different data transformation rules based on configurable conditions.

It evaluates boolean expressions against data fields and selects appropriate datasets for masking based on the evaluation results.

{
  "name": "string",
  "type": "Conditional",
  "conditions": [
    { "if": "boolean_expression", "then": "dataset_name" },
    { "if": "boolean_expression", "then": "dataset_name" },
    { "otherwise": "default_dataset_name" }
  ]
}

Properties

• name (string, required): Unique identifier for the conditional dataset
• type (string, required): Must be "Conditional"
• conditions (array, required): Array of condition objects that define the evaluation logic

Condition objects

If-Then Conditions

{ "if": "boolean_expression", "then": "dataset_name" }

• if (string, required): Boolean expression that evaluates to true or false
• then (string, required): Name of the dataset to use when the condition is true
• required: At least 1 if-then condition must exist in a conditional dataset.

Otherwise

 { "otherwise": "default_dataset_name" } 

• otherwise (string, required): Default dataset used when no if-conditions evaluate to true
• required: Exactly 1 otherwise condition must exist in a conditional dataset.

Expression Syntax

Referencing the current value

• Use ${value} to reference the value currently being masked

Referencing the value of a field

• Use $[FieldName] to reference column values
• Example: $[Type], $[CustomerName]
• Note: Using a field will only work for datasets defined at the table level, it is not possible to define a global level dataset that uses a field.
