Question

Accepted Answer

Master detail and drill through are two different techniques used in Cognos reporting.

Master detail is used to display data in a hierarchical manner, where the details are shown based on a selected master item.
Drill through allows users to navigate from summary information to detailed information by clicking on a specific data point.
Master detail is typically used for displaying related data in a structured format, while drill through is used for exploring data in more detail.
Master detail reports often have a parent-child relationship, while drill through reports provide a way to access additional information.
For example, in a master detail report, you can have a list of customers as the master and their orders as the details. Clicking on a customer will show their specific orders. In a drill through report, you can have a summary sales report and drill down to view sales by region, then drill further to view sales by individual store.
