About this site

SAP is used by a very large number of companies, yet structured introductory material — particularly in Japanese — is surprisingly scarce. Official documentation is accurate but voluminous, and hard to work through without prior context. Scattered blog posts, on the other hand, rarely show how the modules connect.

This site aims at the space in between. Each section is a five to ten minute read, followed immediately by practice questions that check what you retained. Ten sections in, you should have a working picture of the whole module.

Because SAP work regularly crosses between English and Japanese material, every page exists in both languages. Reading the same explanation in both is a practical way to pick up the English terminology you will actually meet on a project.

• People newly assigned to an SAP implementation who need an overview of their module
• Practitioners who want enough grounding in adjacent modules to follow the conversation
• Anyone building a base before starting formal SAP certification study
• Readers who want SAP terminology mapped between English and Japanese

All explanations are original text written for this site, based on standard SAP functionality and standard business processes. Nothing here is reproduced or summarised from other sites.

Three principles guide the writing. Where behaviour depends on the release or deployment model, that is stated rather than glossed over. Terminology follows official SAP naming. Every practice question carries a written explanation of why the answer is what it is.

SAP itself changes continuously, so some descriptions may drift out of step with the current release. If you spot an error or something out of date, please tell us through the contact form — corrections are checked and applied.

All content is free and no account is required. To cover server and domain costs, advertising may appear on some pages in future.

Where ads run, they do not influence the content of the explanations, and they are not placed inside articles in a way that could be mistaken for the text itself.
