IDocs

Quick answer

Understanding IDoc structures and where to find their documentation is essential for integration, mapping fields, troubleshooting failures (status 51), and extending IDocs with custom segments.

Key takeaways

  • An IDoc type defines the structure of a business document (segments and fields) exchanged via ALE/EDI.
  • Use WE60 for IDoc-type documentation (segments/fields).
  • Use WE30 (IDoc types) and WE31 (segments) to view structures.
  • Watch out: Guessing instead of using the reference tools.

What it is

An IDoc type defines the structure of a business document (segments and fields) exchanged via ALE/EDI. Each represents a document kind (e.g. ORDERS for purchase orders, MATMAS for material master), with a message type controlling its use.

How to find/use it

  • Use WE60 for IDoc-type documentation (segments/fields).
  • Use WE30 (IDoc types) and WE31 (segments) to view structures.
  • Use WE02/WE05 to view IDoc instances and statuses.
  • Match message type and IDoc type when configuring partner profiles.

Why it matters

Understanding IDoc structures and where to find their documentation is essential for integration, mapping fields, troubleshooting failures (status 51), and extending IDocs with custom segments.

Common pitfalls

  • Guessing instead of using the reference tools.
  • Editing/using without understanding the object.
  • Relying on memory for details you can look up.
