• What is the cause and solution for SAP error message WZRE_ALE_MONITOR2011 - IDoc type can not be determined (Message type is not unique) ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WZRE_ALE_MONITOR2011: IDoc type can not be determined (Message type is not unique)
  
  Cause:
  This error occurs during ALE/IDoc processing when the system tries to determine the IDoc type for a given message type, but finds multiple IDoc types assigned to the same message type. In other words, the message type is not unique because it is linked to more than one IDoc type in the system.
  This ambiguity prevents the system from deciding which IDoc type to use for processing the inbound or outbound IDoc.
  
  Explanation:
  
  In SAP, a message type is linked to an IDoc type (basic type) to define the structure of the IDoc.
  Normally, each message type should be assigned to exactly one IDoc type.
  If multiple IDoc types are assigned to the same message type, the system cannot determine which IDoc type to use.
  This situation can happen due to incorrect configuration in the distribution model or in the IDoc type assignments.
  
  
  Where to Check:
  
  Transaction WE81: Check the assignment of message types to IDoc types.
  Transaction WE82: Check the assignment of message types to process codes.
  Transaction BD64: Check the distribution model for message type assignments.
  Transaction WE20: Partner profiles and message type assignments.
  
  
  Solution:
  
  
  Identify the message type causing the problem.
  
  
  Check the message type to IDoc type assignments:
  
  Go to transaction WE81.
  Enter the message type.
  Verify if more than one IDoc type is assigned.
  
  
  
  Correct the assignment:
  
  Ensure that the message type is assigned to only one IDoc type.
  Remove or correct any duplicate or incorrect assignments.
  
  
  
  Check the distribution model (BD64):
  
  Make sure the message type is correctly assigned to the appropriate IDoc type for the relevant sender/receiver systems.
  
  
  
  Check partner profiles (WE20):
  
  Verify that the message type and process code assignments are consistent and unique.
  
  
  
  If multiple IDoc types are legitimately needed for the same message type (rare case):
  
  You may need to differentiate by process codes or use different message types.
  Alternatively, custom logic may be required to handle the differentiation.
  
  
  
  After corrections, reprocess the IDoc or restart the ALE process.
  
  
  
  Additional Notes:
  
  This error is common when custom developments or configurations have been done without proper alignment.
  Always ensure that the message type to IDoc type mapping is one-to-one.
  If you are unsure about which IDoc type to keep, consult the functional team or SAP documentation for the specific business process.
