Reference hub

Quick answer

SAP is vast; no one memorises it all.

Key takeaways

  • Learn a concept in its lesson, then come here (or to the linked detail pages) to confirm the exact TCode, table field, or API.
  • Transaction codes (TCodes) and what they do.
  • Tables and their key fields and relationships.
  • Watch out: Reading reference like a tutorial, learn the concept first.

What the reference covers

  • Transaction codes (TCodes) and what they do.
  • Tables and their key fields and relationships.
  • Function modules, classes, methods, BAPIs.
  • Data elements, domains, IDocs, messages, CDS views.

How to use it

Learn a concept in its lesson, then come here (or to the linked detail pages) to confirm the exact TCode, table field, or API. In-system reference tools (SE11 for tables, SE37 for function modules, the BAPI Explorer, WE60 for IDocs) complement these pages.

Why a reference matters

SAP is vast; no one memorises it all. Knowing where to look up the precise detail, and understanding what you find, is a core professional skill and a huge SEO opportunity, because practitioners search for these specifics constantly.

Common pitfalls

  • Reading reference like a tutorial, learn the concept first.
  • Not using in-system reference tools.
