• What is the cause and solution for SAP error message SDEST036 - Logon data inconsistent; user not unique ?

  The SAP error message SDEST036 indicates that there is an inconsistency in the logon data for a user, specifically that the user is not unique. This typically occurs when there are multiple entries for the same user in the system, which can lead to confusion during the logon process.
  Cause:
  
  Duplicate User Entries: The most common cause of this error is that there are multiple user records in the system with the same user ID or logon credentials.
  Incorrect User Configuration: There may be issues with the user configuration in the user master records, such as incorrect roles or profiles assigned.
  Transport Issues: If user data has been transported between systems (e.g., from development to production), inconsistencies may arise if the transport was not handled correctly.
  
  Solution:
  To resolve the SDEST036 error, you can follow these steps:
  
  
  Check User Records:
  
  Use transaction code SU01 to check the user master records.
  Look for duplicate entries for the user ID in question. If duplicates exist, you may need to delete or merge them.
  
  
  
  User Comparison:
  
  Use transaction code SU10 to perform a mass user comparison. This can help identify any inconsistencies across user records.
  
  
  
  User Lock/Unlock:
  
  Ensure that the user is not locked or has expired credentials. You can check this in the user master record.
  
  
  
  Check Authorization Profiles:
  
  Verify that the user has the correct authorization profiles assigned. Sometimes, incorrect profiles can lead to logon issues.
  
  
  
  Transport Management:
  
  If the issue arose after a transport, check the transport logs for any errors related to user data. You may need to re-transport the user data or correct any inconsistencies.
  
  
  
  System Logs:
  
  Check the system logs (transaction code SM21) for any additional error messages that might provide more context about the issue.
