Extended Program Check 
Use
You use this function to perform static checks, which are too time consuming for the normal syntax check. The extended program check returns both errors and warnings and it is possible to run either individual specialized tests or one whole standard check.
Procedure
...
1. You access the extended program check by means of transaction SLIN. You can also choose Program ® Check ® Extended program check.
The system displays a list of possible check options. By default, all of them are selected. For detailed information about a particular option, position the cursor on it and choose F1.
The extended program check takes considerably longer time than other checks but it uses a buffer and the process speeds up after the first run.
2. Select any options you need.
For each option you have selected, the system displays an overview of the number of errors, warnings, and messages.
Only the especially critical warnings are displayed before the standard check.
3. Choose an entry to display the corresponding detail screen.
From that screen you can jump to the appropriate point in the program and correct the error.
