• What is the cause and solution for SAP error message WE_MSG001 - Assignment object of type & with ID & does not exist ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WE_MSG001: Assignment object of type & with ID & does not exist
  
  Meaning / Cause:
  This error occurs in the context of IDoc processing or ALE (Application Link Enabling) when the system tries to find an assignment object (such as a partner profile, logical system, or other configuration object) by its type and ID, but it cannot find it in the system.
  
  The placeholders & are replaced by the actual object type and ID in the error message.
  Essentially, the system is trying to reference an object that has not been created or is not maintained in the system.
  Common scenarios include:
  
  Missing partner profile or partner type in WE20.
  Missing logical system in BD54 or in the system landscape.
  Missing message type or message variant.
  Incorrect or incomplete configuration in ALE or IDoc distribution model.
  
  
  
  
  Typical Causes:
  
  Partner Profile Not Maintained: The partner profile (WE20) for the partner type and partner number does not exist.
  Logical System Not Defined: The logical system ID used in the message does not exist in the system (transaction BD54).
  Incorrect or Missing ALE Configuration: The distribution model (transaction BD64) does not contain the required entries.
  Incorrect Message Type or Object Type: The message type or object type referenced in the IDoc or ALE configuration is not maintained.
  Transport or Client Copy Issues: Sometimes, after a client copy or transport, the configuration objects are missing.
  
  
  How to Identify:
  
  Check the exact object type and ID in the error message.
  Use transaction WE20 to verify partner profiles.
  Use transaction BD54 to check logical systems.
  Use transaction BD64 to check the distribution model.
  Check the IDoc status and details in WE02 or WE05.
  Review the ALE configuration and partner agreements.
  
  
  Solution / Resolution Steps:
  
  
  Maintain Partner Profile:
  
  Go to transaction WE20.
  Check if the partner type and partner number (ID) exist.
  If missing, create the partner profile with the correct parameters.
  
  
  
  Maintain Logical System:
  
  Go to transaction BD54.
  Verify if the logical system ID exists.
  If missing, create the logical system.
  
  
  
  Check Distribution Model:
  
  Go to transaction BD64.
  Verify if the message type and logical systems are correctly assigned.
  Add missing entries and generate the model.
  
  
  
  Verify ALE Configuration:
  
  Check the partner agreement in WE20.
  Ensure the message types and process codes are correctly assigned.
  
  
  
  Check IDoc Data:
  
  Use WE02 or WE05 to check the IDoc.
  Verify the partner number and type in the IDoc control record.
  
  
  
  Transport / Client Copy:
  
  If the error appeared after a transport or client copy, ensure that all ALE and partner profile configurations were transported correctly.
  
  
  
  
  Additional Information:
  
  This error is common in ALE/IDoc scenarios where partner profiles and logical systems are critical for message routing.
  Always ensure that the system landscape is correctly maintained and consistent across clients and systems.
  For complex scenarios, check the SAP Note related to ALE and IDoc partner profile errors.
  Debugging the function module or program that raises this error can provide more insight into which object is missing.
