Dieses ABAP-Programm (Z_USEREXIT) ist ein umfassendes Werkzeug, das alle möglichen Kundenerweiterungen im System basierend auf einem bestimmten Transaktionscode (TCode) oder Hauptprogrammnamen scannt, analysiert und auflistet. Es bietet großen Komfort, insbesondere bei der Suche nach geeigneten Eingriffspunkten im Standard-SAP-Code oder bei der Nachverfolgung der bestehenden Architektur.
Die Hauptfunktionen des Programms sind wie folgt:
Tiefgehende Code-Analyse: Es scannt den Quellcode des angegebenen Programms und die zugehörigen Includes, Funktionsbausteine und submittierten Programme mit dem Befehl SCAN ABAP-SOURCE.
Umfassende Erweiterungserkennung: Es analysiert die Schlüsselwörter (Tokens) im Quellcode, um die folgenden Objekte zu identifizieren:
- User-Exits / Customer-Functions: (SMOD / CMOD Aufrufe)
- BAdIs (Business Add-Ins): (cl_exithandler Verwendungen und SE18 Integration)
- BTEs (Business Transaction Events): (OPEN_FI_PERFORM Verwendungen und FIBF Aufrufe)
- Programm-Exits: (USEREXIT_... Form-Routinen)
- Berechtigungsprüfungen und Workflow-Trigger (SWE_EVENT_CREATE).
Status- und Versionsverfolgung: Es ruft die Details der gefundenen Erweiterungen (Projektname, Aktivierungsstatus, wer es wann geändert hat) aus den relevanten Systemtabellen (MODSAP, SXS_ATTR, MODACT, etc.) ab und fügt sie dem Bericht hinzu.
Interaktives Reporting: Es präsentiert die Ergebnisse je nach Benutzerwunsch im ALV Grid oder im Standard-ABAP-Listenformat mit Farbcodierung. Wenn ein Entwickler auf ein Objekt in der Liste klickt, wird er direkt zum entsprechenden Transaktionscode (SMOD, CMOD, SE18, etc.) navigiert.
Zusammenfassend lässt sich sagen, dass dieser Report ein leistungsstarkes Reverse-Engineering-Werkzeug ist, das verwendet wird, um den am besten geeigneten und datengesteuerten Lösungspunkt (Erweiterung) zu finden, ohne sich in der Code-Architektur zu verlieren.
