Education
- Technischer Hintergrund in Softwareentwicklung und Enterprise-IT – als Basis für robuste SAP-Lösungen über viele Jahre hinweg.
- Continuous SAP training in technical development (ABAP/ABAP OO, dialogue and batch programming, SAPscript).
- In-depth knowledge of SAP enhancement and integration concepts (enhancements, BAdIs, user/customer exits, RFC, IDoc).
- Process-oriented understanding through technical specialisation in key SAP areas such as PP, PP-PI, SD, MM, LO, WM, EWM, QM, PM (EAM), FI/CO and APO.
- Practical training courses and workshops for implementation in everyday project work (e.g. WebDynpro, UI-oriented development, clean extension strategies).
- Add-on strategy & productisation: From the idea to the release-ready add-on, including namespace/object strategy, versioning, documentation and clean delivery (transport/deployment).
- Development concepts & governance: Clean core-oriented extension architecture, coding guidelines, ATC/code reviews, test & quality gates for long-term maintainable solutions.
With nearly 25 years of experience in SAP development and consulting, Thomas Jetzinger combines an exceptional breadth and depth of expertise – from ABAP/ABAP OO, interfaces (IDoc/RFC) and enhancements (BAdIs, user/customer exits) to practical solutions in modules such as SD, MM, LO and APO. This enables him to quickly grasp business processes and requirements, translate them into robust, maintainable implementations and reliably support their implementation – from dialogue and batch programming to reports and modern SAP interfaces. With his analytical approach (including in areas such as decision-making and process analysis), he develops targeted solutions that work in everyday life and create measurable added value.
Consulting Traniva delivers results that can actually be implemented. That is our strength compared to other consulting firms.
Thomas Jetzinger brings over two decades of experience in SAP development and technical consulting to the table and stands for solutions that are stable in operation and provide real benefits in everyday use. In numerous projects that we have implemented together, he has quickly grasped complex requirements, structured them clearly and translated them into maintainable ABAP/ABAP OO implementations – from classic reports and dialogue transactions to interfaces, enhancements and performance-critical components.
Thomas places particular emphasis on the design and development of SAP add-ons: from the overall technical architecture, namespace/versioning and transport concepts to productisation, documentation and release readiness. He combines pragmatic implementation with a strong focus on quality (code standards, reviews, testability) and always keeps the process and end-to-end view in mind. This results in solutions that not only work, but are also sustainable in the long term – even in heterogeneous system landscapes and with changing business requirements.
