Introduction
When using the query runtime statistics, you can determine how much time the execution of a certain query or a certain navigation step take in the front end and in the analytic manager. Basically, the statistics records can be analyzed by using the technical content (TCT), the transaction RSRT (AdHoc Analysis) or two table views. In particular when you want to analyze a performance problem concerning a certain query, transaction RSRT offers the most convenient way to take a look at the query runtime statistics. See also Query Performance.
Since query runtime statistics generate a very large amount of statistics data, it is recommended to activate this feature only for queries where it is really required. In addition, normally it is also necessary to delete statistics data on a regular basis.
