AI Solution Architecture and ERP Integration

AI projects often shine in the demo and fade in production. I build the architecture on data, security and measurable business value from the start.

  • LLM
  • RAG
  • Document AI
  • SAP Integration
  • Automation

What I design as an AI architect

An enterprise AI solution is much more than wiring a model to an API. Which data reaches the model, how the output is validated, which systems it writes to and how all of it is monitored are architectural decisions. As an AI architect and project specialist I make those decisions together with the business goal.

  • Use-case selection: frequent, rule-bound tasks where errors are measurable
  • Data and context: RAG (answers grounded in internal documents), document parsing, structured output
  • Integration: controlled access to SAP via BAPI/OData and to other systems via REST APIs
  • Security and compliance: data protection (KVKK/GDPR), masking, authorisation, logging and audit trail
  • Measurement: accuracy, processing time, human-intervention rate and cost metrics

ERP and AI: realistic use cases

  • Extracting data from supplier invoices and order documents, with approved transfer to SAP
  • Classifying customer emails and turning them into order or request records
  • Summarising SAP reports in natural language and explaining variances
  • Question-answering assistants over internal process documentation

From pilot to production

Every project starts with a narrow, measurable pilot. I define the success criteria (for example accuracy and time saved) up front and widen the scope only once they are met. I also build a provider-independent layer so the system keeps working even when the model changes.

Architecture backed by software expertise

I do not leave the architecture on paper; with my software expertise in PHP/Laravel and REST APIs I build the integration itself. The AI assistant on this site follows the same approach: keys and rules stay on the server, and requests are rate-limited.

Frequently asked questions

Where should we start with AI?

With one frequent, rule-bound task whose outcome is measurable. Extracting data from supplier invoices is a good start: accuracy and time saved are easy to measure.

Will our company data go to the AI provider?

It depends on the architecture. Sensitive fields can be masked, enterprise APIs that do not retain data can be used, or on-premise models can be chosen for suitable scenarios. The decision is made at the start alongside data-protection and security requirements.

Can AI change SAP data directly?

My advice is no, at least initially. Model output first becomes a structured proposal, a user approves it, and only then is it written to SAP through standard interfaces. Automation increases as trust is established.
