FAQ
Frequently Asked Questions about ERP and SAP Consulting
What does an ERP consultant do?
An ERP consultant analyses a company's business processes and guides the selection, configuration and go-live of the right ERP system. They gather requirements, identify fit-gaps between process and system, plan testing and user training, and manage improvements after go-live.
What does an SAP SD consultant cover?
An SAP SD consultant owns the whole sales and distribution flow: sales organisation structure, order types, the pricing procedure (condition technique), delivery, billing, credit management and export scenarios. They also design the integration points with FI, MM and CO-PA.
How is AI integrated into ERP systems?
The safest route is to start with read-only access and a narrow use case, such as extracting data from invoices or order documents. The LLM output is turned into structured data, reviewed by a user, and only then written to SAP via BAPI/OData.
Do you do custom ABAP development?
Yes. Where standard SAP falls short I build enhancements with BAdIs, Enhancement Spots and User Exits, plus custom reports and interfaces. My priority is always to configure the standard correctly first and write custom code only when it is truly needed.
Where do you work?
I am based in Konya, Türkiye, and support projects across Türkiye and abroad, remotely or on site. Meetings can be held in English or Turkish.
Why work with an independent ERP solution partner?
An independent consultant earns nothing from licence sales, so recommendations are driven only by your processes and budget. That means a neutral comparison during selection and quality control on your behalf during implementation.
