Description

I am a Senior Consultant for SAP SD / Order-to-Cash and EDI/B2B integration with over 15 years of experience and a strong automotive background – complemented by an AI focus that builds on this specific expertise. I am consulted when IDoc errors block dispatch, a Seeburger connection fails after a partner change, or a critical interface ticket needs to be resolved quickly – often in (partial) project management. My deepest and most frequently requested strength is EDI – on par with SD: Seeburger BIS6 (Mapping, Monitoring, Error Analysis, Reprocessing), SAP-IDoc/ALE (WE20/WE19/BD87), Partner Integration and Legacy Migration, EDIFACT (VDA, EANCOM, Odette), X12 and XML via AS2/OFTP2/SFTP – including E-Invoicing (XRechnung, Factur-X, Peppol; FR PDP, MY MyInvois; EU-ViDA-ready). In SD, I cover dispatch/delivery, JIT/JIS, Self-Billing, Advanced Intercompany incl. ARM, aATP and Condition Contract Management, plus SAP GTS (Sanction List Screening, Legal Control, Embargo, Preference; Replacement of MIC).

Proven by real projects: Co-responsible for Outbound Template (SD/EWM/TM) for 100+ plants, managed a core team of 12, coordinated 50+ consultants and key users; led E-Invoicing projects in France and Malaysia.

The AI focus is intended as a factual demonstration, not a product sale: In a fully activated SAP lab (S/4HANA 2023 + ECC 6.0), I keep my knowledge up-to-date and have built and end-to-end demonstrated "Telaflux" on it – an AI-supported automation toolkit based on the principle: AI suggests, a deterministic gate checks, SAP executes transport-safely. If necessary, I go down to the ABAP level via User Exit/BAdI.

If you want to stabilize an unstable interface or secure an S/4 transformation, I will support you in a goal-oriented manner – on-site in the Stuttgart region or remotely. Native German speaker, fluent in English.
