• What is the cause and solution for SAP error message LK004 - No receiver found for message type & ?

  The SAP error message LK004 ("No receiver found for message type &") typically occurs in the context of the SAP ALE (Application Link Enabling) or IDoc (Intermediate Document) processing. This error indicates that the system is unable to find a suitable receiver for the specified message type, which can prevent the successful processing of IDocs.
  Causes:
  
  Missing Partner Profile: The partner profile for the sender or receiver may not be correctly configured or may be missing entirely.
  Incorrect Message Type: The message type specified in the IDoc may not be defined in the system or may not have a corresponding receiver.
  Logical System Configuration: The logical system for the sender or receiver may not be properly set up in the SAP system.
  Filter Settings: The filter settings in the partner profile may be too restrictive, preventing the message from being routed correctly.
  Transport Layer Issues: There may be issues with the transport layer configuration that prevent the message from being sent to the intended receiver.
  
  Solutions:
  
  
  Check Partner Profiles:
  
  Go to transaction WE20 and verify the partner profiles for both the sender and receiver. Ensure that the correct message type is included in the profile.
  Make sure that the partner profiles are active and correctly configured.
  
  
  
  Verify Logical Systems:
  
  Check the configuration of logical systems in transaction SALE (or SPRO for customizing) under "Basic Settings" -> "Logical Systems". Ensure that the logical systems are correctly defined and assigned.
  
  
  
  Review Message Type Configuration:
  
  Use transaction WE81 to check if the message type is defined and if it has the necessary configurations.
  Ensure that the message type is correctly mapped to the appropriate IDoc type.
  
  
  
  Check Filter Settings:
  
  In the partner profile, review the filter settings for the message type. Ensure that they are not too restrictive and allow for the intended messages to be processed.
  
  
  
  Test IDoc Processing:
  
  Use transaction WE19 to test the IDoc processing. This can help identify if the issue is with the IDoc itself or the configuration.
  
  
  
  Review Logs:
  
  Check the IDoc processing logs in transaction WE02 or WE05 for additional details on the error and to see if there are any related messages that can provide more context.
