• What is the cause and solution for SAP error message WZRE_ALE_MONITOR2021 - 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_MONITOR2021 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 given logical system and message type combination.
  
  Partner Profile: Defines how IDocs are sent or received between systems.
  The system is trying to process or send an IDoc but cannot find a partner profile that matches the sender/receiver logical system, message type, and process code.
  The placeholders &1, &2, and &3 typically represent:
  
  &1: Logical system (partner)
  &2: Message type
  &3: Process code
  
  
  
  
  Common Causes:
  
  Missing Partner Profile: The partner profile for the specified logical system and message type does not exist.
  Incorrect Logical System: The logical system name in the partner profile does not match the one used in the IDoc.
  Wrong Message Type or Process Code: The message type or process code in the partner profile is incorrect or missing.
  Partner Profile Not Maintained for the Direction: The partner profile might be maintained only for inbound or outbound, but the current operation requires the other direction.
  ALE Configuration Issues: Logical system not properly configured or distributed in transaction BD54.
  Incorrect Port or Partner Type: The partner profile might be maintained with wrong partner type (e.g., LS, KU, LI).
  
  
  How to Check / Solution:
  
  
  Check Partner Profiles (WE20)
  
  Go to transaction WE20.
  Select the partner type (usually LS for logical system).
  Check if the partner profile for the logical system &1 exists.
  Verify that the message type &2 and process code &3 are maintained correctly.
  Ensure the partner profile is maintained for the correct direction (inbound/outbound).
  
  
  
  Verify Logical System Names
  
  Check the logical system name in BD54 (Logical Systems).
  Make sure the logical system name matches exactly with the one in the partner profile.
  
  
  
  Check Message Type and Process Code
  
  Confirm that the message type and process code are correctly assigned in the partner profile.
  The process code should correspond to the function module that processes the IDoc.
  
  
  
  Maintain Partner Profile if Missing
  
  If the partner profile is missing, create a new one with the correct logical system, message type, and process code.
  
  
  
  Check ALE Distribution Model (BD64)
  
  Ensure the distribution model is correctly maintained and activated.
  The logical systems involved should be part of the model.
  
  
  
  Check Port Configuration (WE21)
  
  Verify that the port used for communication is correctly configured and assigned in the partner profile.

  Summary:
  
  
  
  Aspect
  Details
  
  
  
  
  Cause

  Solution
  Maintain or correct partner profile in WE20 with correct logical system, message type, and process code.
  
  
  Check
  Logical system names (BD54), distribution model (BD64), ports (WE21), and IDoc monitoring (WE02).
