Hi,
we are using the ABAP code checker from VIRTUALFORGE to improve our custom ABAP code and to remove the security leaks.
This software is used in our whole company with global company specific settings and checks. It checks and scans all custom ABAP code on production system periodically. Additionally there is a scan tool to check the code on development system before transporting it to QA / PROD.
It's very useful in my mind.
Best regards,
Klaus
