Setting Up Agile Planner → Configuration → Attributes Setup → Attribute Dependencies
The Attribute Dependencies tab allows you to link attributes to each other by defining a parent/child relationship. You can define parent/child relationships for any attribute type that can be associated with a list, such as date, float, integer, money, percent, or text.
After you have chosen the parent and child attributes, you need to define the dependency relationships. Select a list work item from the parent attribute and then associate a value from the child attribute by adding a list work item from the child attribute to the list work item of the parent attribute.
Open the New Attribute Dependency dialog box and choose the parent and child attributes. Then specify the relationships between a list work item which belongs to the parent and child attributes.
If you are not using an attribute dependency, you can delete it.
Make your changes and then save them.
An attribute dependency can be viewed from the Attribute Dependencies tab in the Attributes Setup tab.
