Built by someone who's actually been on the project floor.
The SD Vault is the SAP SD reference and interview preparation platform I always wished existed when I started. After 17+ years of implementing, troubleshooting, and architecting SAP Sales & Distribution solutions across ECC and S/4HANA, I built it for the next generation of SAP SD consultants.
Who I am
I'm Rahul Narain Saxena, an SAP SD Solution Architect with 17+ years of hands-on experience. I've delivered SAP SD across SAP ECC 6.0 and SAP S/4HANA implementations, from greenfield rollouts to brownfield migrations and complex integrations.
My core depth is in pricing & condition technique, credit management (both classic and FSCM), output determination, FI-SD integration, and the order-to-cash cycle end-to-end. I've worked across geographies and industries — manufacturing, retail, automotive, and services — which means I've seen every flavour of edge case the textbook never warns you about.
Why this platform exists
Most SAP SD prep material online has three problems: it's outdated (still recommending FD32 in 2026), it's shallow (a hundred questions with one-line answers), or it's stitched together from forum posts by people who've never sat in an SD configuration session.
I built The SD Vault to be the opposite. Every interview question is graded by depth — from "freshers will be asked this" all the way to "principal consultant interview". Every scenario is a real configuration exercise from a real project, with the IMG paths, T-codes, and gotchas that you only learn the hard way. Every reference page (T-codes, tables, pricing, credit, O2C) flags exactly what changed between ECC and S/4HANA so your knowledge doesn't quietly age.
How content is built
- 01.Source from real projects. Every scenario, T-code, and configuration walkthrough comes from work I've done or reviewed on live SAP implementations — not paraphrased from a 2008 blog.
- 02.S/4HANA-first, ECC-aware. Where ECC and S/4HANA differ (BP vs XD01, KONV vs PRCD_ELEMENTS, FD32 vs FSCM Credit), both are explained and the modern path is made obvious.
- 03.Depth grading. Interview questions are tagged so a fresher knows what to focus on and a senior consultant can skip past the basics straight to the principal-level material.
- 04.Continuously updated. The platform is updated for SAP S/4HANA 2026. When a transaction is deprecated or a new feature lands, the relevant pages are refreshed and re-published.
