• What is the cause and solution for SAP error message EA771 - Basic type & is not linked with any logical message ?

  The SAP error message EA771 indicates that a specific basic type is not linked to any logical message in the system. This typically occurs in the context of Electronic Data Interchange (EDI) or Intermediate Document (IDoc) processing, where the system expects a certain configuration that is not present.
  Cause:
  
  Missing Configuration: The basic type specified in the error message is not associated with any logical message type in the system. This can happen if the necessary configuration has not been set up in the EDI/IDoc settings.

  Transport Issues: If the configuration was recently transported from another system, it may not have been transported correctly, leading to missing links.

  Check Configuration:
  
  Go to transaction code WE30 to check the basic type configuration.
