ABAP retrieve statistical data from the STAT file

REPORT ZSTATFILE LINE-SIZE 164.
************************************************************************
* This is an example of how to dig out some interesting performance
* and statistical data from the STAT file.
* The program creates a rank list of users based upon their database
* update and read activity. The results are the accumulated database
* time and row number per user for the different categories:
* insert/delete/modify and sequential/direct read. The results can be
* sorted by any of these categories.
* There are a lot more interesting data in the STAT file that can
* be used to write similar programs.
