• Collaborate closely with technical teams (ABAP, Basis) on performance tuning, debugging custom code, and applying SAP notes/patches.
• Execute system configuration and master data updates required for incident resolution and approved minor change requests, ensuring adherence to change control processes.
• Support the transition‑to‑operations (TTO) process for all new fixes and small enhancements, ensuring smooth deployment and stable handover to L1/L2 support.
• Maintain the health and integrity of the IS‑U production environment by routinely reviewing system logs, batch job status, and background process performance.

Solution Development & Customization:

• Perform in‑depth analysis and troubleshooting (L2/L3) of complex, cross‑module incidents, utilizing debugging tools (e. g. , ABAP debugger) to pinpoint root causes.
