Master Data Indexes 
Use
The information system for Controlling provides you with master data indexes for business processes , cost objects , cost centers , cost elements , activity types , and internal orders , as well as for statistical key figures . This enables you to check at any time, which master data has been maintained within the system. From the master data index, you can branch to the master data records of the displayed objects. Therefore, from the information system you have access to all information relating to the Controlling (CO) master data.
