Smart SAP Assistant

• What is the cause and solution for SAP error message WZRE_ALE_MONITOR021 - No suitable partner profile found (LS / &1 / &2 / &3) ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WZRE_ALE_MONITOR021 No suitable partner profile found (LS / &1 / &2 / &3)
  
  Meaning / Cause:
  This error occurs in the context of ALE (Application Link Enabling) or IDoc processing. It indicates that the system could not find a suitable partner profile for the specified logical system and message type combination.
  
  LS = Logical System
  &1 = Partner Logical System
  &2 = Message Type
  &3 = Direction (e.g., inbound or outbound)
  
  In other words, when the system tries to process or send an IDoc, it looks for a partner profile that matches the logical system, message type, and direction. If no such partner profile exists or is incorrectly configured, this error is raised.
  
  Common Causes:
  
  Missing Partner Profile: The partner profile for the specified logical system and message type does not exist.
  Incorrect Partner Profile Configuration: The partner profile exists but does not cover the message type or direction required.
  Logical System Not Defined: The logical system name used in the partner profile or in the IDoc processing is incorrect or missing.
  ALE Distribution Model Issues: The distribution model may not be properly maintained or activated for the message type and logical system.
  Incorrect Port or Partner Type: The partner profile might be created for the wrong partner type (e.g., LS, KU, LI) or wrong port.
  
  
  Solution / How to Fix:
  
  
  Check Partner Profiles:
  
  Go to transaction WE20.
  Verify that a partner profile exists for the partner logical system (&1).
  Check that the message type (&2) is maintained under the correct partner and direction (&3).
  If missing, create or adjust the partner profile accordingly.
  
  
  
  Verify Logical Systems:
  
  Use transaction SALE or BD54 to check the logical systems.
  Ensure that the logical system names are consistent across the system and partner profiles.
  
  
  
  Check Distribution Model:
  
  Use transaction BD64.
  Verify that the distribution model includes the relevant message type and logical system.
  If missing, add and activate the model view.
  
  
  
  Check Ports:
  
  In WE20, verify that the correct port is assigned to the partner profile.
  Ensure the port is correctly configured in transaction WE21.
  
  
  
  Reprocess IDocs:
  
  After correcting the partner profile, reprocess the IDocs in transaction WE02 or WE19.
  
  
  
  Check Partner Type:
  
  Ensure the partner type is set to LS (Logical System) if the partner is a logical system.
  
  
  
  
  Additional Information:
  
  This error is common during initial ALE setup or when new message types or logical systems are introduced.
  The partner profile controls how IDocs are processed and routed; missing or incorrect profiles block IDoc processing.
  Always ensure that the partner profile matches the exact combination of logical system, message type, and direction.
  For inbound IDocs, the partner profile must be maintained in the receiving system.
  For outbound IDocs, the partner profile must be maintained in the sending system.
