• What is the cause and solution for SAP error message B5ALE026 - Object type/object/object key is not unique! group: & ?

  The SAP error message B5ALE026 indicates that there is a problem with the uniqueness of an object type, object, and object key combination in the context of ALE (Application Link Enabling) or IDoc processing. This error typically arises when the system encounters multiple entries that match the specified criteria, which should be unique.
  Cause:
  
  Duplicate Entries: The most common cause of this error is that there are duplicate entries in the relevant tables for the specified object type and key. This can happen due to incorrect data entry, data migration issues, or system inconsistencies.
  Configuration Issues: Incorrect configuration in the ALE settings or IDoc processing can lead to this error, especially if the system is expecting unique identifiers but finds multiple matches.
  Data Replication Issues: If data is being replicated between systems (e.g., from a source system to a target system), and there are duplicates in the source, this error may occur during the replication process.
  
  Solution:
  
  
  Check for Duplicates: 
  
  Use transaction codes like SE11 or SE16 to check the relevant database tables for duplicate entries. Look for the specific object type and key that is causing the issue.
  If duplicates are found, you may need to delete or correct them to ensure uniqueness.
  
  
  
  Review Configuration:
  
  Check the ALE configuration settings in transaction WE20 (Partner Profiles) and WE21 (Port Definitions) to ensure that they are set up correctly.
  Ensure that the logical system settings and message types are correctly defined.
  
  
  
  Data Consistency:
  
  If the error occurs during data replication, ensure that the source system does not have duplicates. You may need to clean up the data in the source system before attempting replication again.
  
  
  
  Error Logs:
  
  Review the error logs in transaction SLG1 for more detailed information about the error and the context in which it occurred. This can provide insights into what specific object is causing the issue.
  
  
  
  Testing:
  
  After making corrections, test the process again to ensure that the error does not reoccur.
