LinkListAttributeSum business rule

The LinkListAttributeSum business rule calculates the sum of a Float or Integer attribute for elements that are in a Link, Link List, or Incoming Links attribute.
The sum is displayed in the business rule container attribute. When changes occur, the sum is automatically recalculated. Use this business rule when you want to aggregate data, such as estimates or cost figures from requirements in a release or projects in a portfolio.
Note: Do not use the LinkListAttributeSum business rule for Incoming Link attributes that only display links from views.
