IDoc message/basic type

IDoc message type is not assigned to the expected basic type

IDoc generation or processing fails because message-type/basic-type mapping is missing or inconsistent.

Likely root causes

  1. Message type is not assigned to the basic type/extension expected by the interface.
  2. Custom message type/basic type transport is incomplete.
  3. Partner profile references a message type with incompatible IDoc type.

What to inspect

  1. WE82 message-type/basic-type assignment.
  2. WE30 basic type and extension.
  3. WE20 partner parameter message type and basic type.
  4. Transport history for custom ALE objects.

Resolution path

  1. Maintain the correct message/basic-type assignment through ALE configuration.
  2. Align partner profile with the approved interface contract.
  3. Transport missing custom definitions consistently.
  4. Retest generation and inbound syntax with the target type.
