Statistics 
You can perform a statistical analysis of the documentation in one or more development classes. This analysis refers to document classes of the end user documentation type. Technical documentation is not included in the statistics.
To call the statistics, select Utilities ® Statistics. You can choose as follows:
● Development class
○ You can specify exactly one development class
○ You can specify a development class generically (e.g. ZZ*)
○ You can specify a development class range e.g.
■ Development class ZZAA
■ to Development class ZZBB
All development classes in this range are evaluated.
● Language
You specify here, in which language the documentation is to be evaluated.
● Documentation type
You can choose here whether you want to evaluate the original or extensions.
● Buffer size
This input adjusts the internal data read space to the current hardware platform. The default value need not usually be changed.
● Only original system
With this option, you can ensure that – particularly when using generic evaluations, or evaluations for a development class range – only development classes are evaluated, whose original system is the current system.
As generic evaluation generally makes great demands on the System, background processing is allowed. You must first create variants:
...
1. Choose Tools ® ABAP Workbench ® Development ® ABAP Editor.
2. Enter the program name RSTWGZS2.
3. Choose Goto ® Variants.
For further details, refer to the program documentation, which you can display with Help ® Extended help in the program selection screen.
