What is a Definitions Block?

A definitions block is a container for reusable code that defines elements for central and overview pages and column-sets and expand-sets for cross, dive, report, and ad hoc pages. You can define elements, column sets, and expand sets in a definitions block to avoid code duplication. A definitions block is defined at the top of the script and is referenced by data-area blocks.

  definitions { 
    <column-set> 
    <expand-set> 
    <elements> 
  }
