We have already a powerful
ABAP debugger.
Why do we need a new
one ??

Current Status – Classic Debugger
Classic Debugger
Technology
(cid:190) Debugger and debuggeerun in the same (internal) session
(cid:190) Debugger dynpros placed “in-between”
Consequences
(cid:190) Not all ABAP code can be debugged (no RPERFs: Conversion / Field exit))
(cid:190) Not free of side effects (F1, F4 help, list output)
(cid:190) Implementation of new features not always straight-forward
(cid:190) No chance to use modern UI techniques (no ABAP allowed in the debugger !)
We need a new ABAP debugger technology

Goals – New ABAP Debugger
Higher productivity for development & support
using ABAP debugger
(cid:190) More robust debugger architecture (no side effects)
(cid:190) Possibility to implement new features (e.g. a diff tool for
internal tables) faster and with less risks
(cid:190) More flexible & extensible state-of-the-art debugger UI
Use two separated sessions for the
debugger and the application
