You can modify existing report templates or create custom reports templates if you find that the stock report templates do not meet your reporting needs. For example, you might create a custom report template to view data from the Route_Call_Detail table or Termination_Call_Detail table. While these tables provide detailed data for calls, in some cases, standard (stock) report templates do not retrieve data from them due to performance impact.
You might also customize an existing report template to monitor a department's activity and performance, by creating a collection with objects from only that department.
