• What is the cause and solution for SAP error message B1130 - Too many recipients found for message type & in the ALE model ?

  The SAP error message B1130, which states "Too many recipients found for message type & in the ALE model," typically occurs in the context of Application Link Enabling (ALE) when there are too many recipients defined for a specific message type. This can happen when the system attempts to send a message to a large number of logical systems, exceeding the configured limits.
  Cause:
  
  Excessive Recipients: The primary cause of this error is that the number of logical systems (recipients) defined for a particular message type exceeds the maximum limit set in the system.
  Configuration Issues: There may be misconfigurations in the ALE distribution model, where too many systems are assigned to receive the same message type.
  Message Type Definition: The message type may be incorrectly defined or used in a way that leads to an excessive number of recipients.
  
  Solution:
  
  
  Review the Distribution Model:
  
  Go to transaction BD64 (ALE Distribution Model) and check the distribution model for the message type in question.
  Ensure that only the necessary logical systems are included as recipients for the message type.
  
  
  
  Limit the Number of Recipients:
  
  If there are too many logical systems assigned, consider consolidating or limiting the recipients to only those that are necessary for the business process.
  
  
  
  Check Configuration Settings:
  
  Review the configuration settings for the message type and ensure that they align with the business requirements.
  If needed, adjust the settings to reduce the number of recipients.
  
  
  
  Increase the Limit (if applicable):
  
  If your business process genuinely requires sending messages to a large number of recipients, consult with your SAP Basis or technical team to see if the limit can be increased in the system settings.
  
  
  
  Testing:
  
  After making changes, perform tests to ensure that the message can be sent successfully without triggering the error.
