Filtering Data Subset Components

Filtering Data Subset Components

You can define filter criteria for data subset components at the column level.
  1. To create a data subset filter for a column, click the data subset component in the
    Plan Components
    panel.
  2. Select a column from the
    Criteria
    panel to apply the filter to.
    Test Data Manager shows existing filter criteria. You can change the filter criteria or add new criteria.
  3. Choose a method to filter the column data:
    Option
    Description
    Custom
    Create a basic expression or an advanced expression to filter the data.
    Limit
    Limit the subset results by percentage, by absolute value, or by an interval of rows to write to the target.
  4. If you choose the
    Custom
    method, select one of the following options to define a filter:
    Option
    Description
    Basic
    Define a simple expression that includes just an operator and operand. You can use parameters in the expression.
    Advanced
    Define an expression in the
    Expression Editor
    . You can include multiple columns and functions in the expression. You can use parameters in the expression.
