For Constants and Expression Rules I can go in and see all Impacted and Dependen

Unfortunately there is not currently a way to view impacted and dependent rules for Interfaces, Query Rules, or Constants.

As far as I know, the only way to find references to a query rule is to download an application with potential impacted rules and search the XML for the query rule UUID.

For dependencies, you could add them to an application and run the dependency checker.

There is no way to find the impact of query rules and interfaces. Work around - 1. Query rules: Try to create expression query rules instead of query rules. This would increase performace and give impact assessment. If you must create query rule, then invoke that query rule through the expression rule and use this everywhere instead of query rule. 2. Interfaces: Create interface only for the main screen so that its easy to track. For all other sections or sub-interfaces create expression rule instead of interface so that you can keep track of variaous places where a particular section is used.
This is my opinion. This may not suite dependeing on the design philosphy being followed. For more information please visit my blog post below:
