Field rules

Field rules

Configure a field rule based on incoming fields from an upstream transformation. Then configure the field selection criteria and naming convention for the fields.
When you configure a field rule, you perform the following steps:
  1. Choose the incoming fields that you want to include or exclude. To improve processing time and keep a clean set of data, you can include only the incoming fields that you need.
  2. Configure the field selection criteria to determine which incoming fields apply to the rule. If you use the Named Fields selection criteria, you can use a parameter for the incoming fields.
  3. Optionally, choose to rename the fields. To distinguish fields that come from different sources or to avoid field name conflicts, you can rename incoming fields. If you use the pattern option, you can create a parameter to rename fields in bulk.
  4. Verify the order of execution. If you configure multiple rules, you can change the order in which the
    mapping
    task applies them.
You cannot configure field rules on Source transformations or Mapplet transformations that contain sources.
