SAP outbound processing diagnostics

A first-pass structure for finding why an outbound message was not created, not sent, or arrived corrupted at the partner.

Reviewed

Core idea

Outbound processing is the path from a SAP business document to an external system. When an expected outbound message is missing, stuck in the system, or arrives corrupted at the partner, the support goal is to trace the path from document creation through output determination, IDoc generation, and transmission to identify where it failed.

Common symptoms

  • Business document was created but no outbound IDoc was generated.
  • Outbound IDoc exists but is stuck in status 30 or 03.
  • Partner reports receiving the message but the data is wrong or incomplete.
  • Multiple outbound IDocs were generated for the same business document.
  • Outbound processing is slow and messages accumulate.

Likely causes

  • Output not determined: the output condition technique did not trigger the outbound message for this document.
  • Partner profile missing: the receiver partner or message type is not configured in the outbound partner profile.
  • IDoc generation error: the IDoc was created but failed during segment population due to missing master data.
  • Transmission failure: the IDoc was generated but the RFC destination or port is unreachable.
  • Duplicate trigger: the output was triggered multiple times due to document changes or custom logic.

Where to check in SAP

  • WE02 / WE05 — IDoc list filtered by direction 2 (outbound) and partner.
  • NAST — output messages for the business document.
  • WE20 — partner profile outbound parameters.
  • SM59 — RFC destination test.
  • SMQ1 — outbound qRFC queue status.

Key tables / transactions / objects

  • EDIDC / EDIDS — IDoc control and status.
  • NAST — output messages.
  • TRFCQOUT — outbound qRFC queue.

Diagnostic workflow

  1. Identify the business document and the expected outbound message type and partner.
  2. Check NAST or the document output screen to see if the output was determined.
  3. If output was determined, check WE02 for the generated IDoc and its status.
  4. For status 30, check the partner profile (WE20) and RFC destination (SM59).
  5. For status 03, confirm with the partner whether the message was received.
  6. If the IDoc data is wrong, check the IDoc segments against the business document data.

Typical fixes or next actions

  • Create or update the output condition record if the output was not determined.
  • Update the outbound partner profile to include the message type and receiver.
  • Fix master data gaps that cause segment population errors.
  • Fix the RFC destination or port configuration if transmission fails.
  • Investigate duplicate triggers and adjust the change relevance or custom logic.

Support takeaway

Outbound issues are usually output determination, partner profile, or transmission problems. A useful ticket should include: business document number, message type, partner, IDoc number if it exists, expected versus actual status, and any error text from NAST, WE02, or SM59.

Boundaries and non-goals

This page is a diagnostic frame, not an outbound processing configuration guide. It does not cover output determination design, IDoc segment mapping, or port configuration. It does not replace SAP's IDoc documentation.

This is not official SAP documentation and not a replacement for system-specific analysis.
