• What is the cause and solution for SAP error message B1453 - The logical system name &1 has been converted to name &2 in client &3 ?

  The SAP error message B1453 indicates that there has been a change in the logical system name for a particular client. This message typically arises in scenarios involving system copies, client copies, or changes in the configuration of logical systems.
  Cause:
  The error message B1453 occurs when:
  
  A logical system name has been changed or converted from one name to another.
  The system is trying to access or reference the old logical system name, which has been replaced by a new one.
  This can happen during system migrations, upgrades, or when logical system names are manually changed in the configuration.
  
  Solution:
  To resolve the B1453 error, you can take the following steps:
  
  
  Check Logical System Configuration:
  
  Go to transaction code SCC4 to check the client settings and ensure that the logical system names are correctly configured.
  Verify that the logical system name in the client matches the expected name.
  
  
  
  Update Logical System Name:
  
  If the logical system name has changed, you may need to update the relevant configurations in the system where the old logical system name is referenced.
  Use transaction BD54 to maintain the logical system names and ensure that the new name is correctly mapped.
  
  
  
  Adjust RFC Destinations:
  
  If the logical system is used in Remote Function Call (RFC) destinations, check transaction SM59 to ensure that all RFC destinations are updated to use the new logical system name.
  
  
  
  Transport Requests:
  
  If the logical system name change is part of a transport request, ensure that the transport is correctly imported into the target system.
  
  
  
  Check for Dependencies:
  
  Review any dependent configurations or settings that may still reference the old logical system name and update them accordingly.
  
  
  
  Testing:
  
  After making the necessary changes, perform tests to ensure that the system operates correctly without referencing the old logical system name.
  
  
  
  Related Information:
  
  Logical System Names: These are used in SAP to identify different systems in a landscape, especially in scenarios involving data exchange between systems (e.g., ALE, IDocs).
  Client Copy: During a client copy, logical system names may be automatically adjusted, which can lead to this error if not properly managed.
  System Copy: When copying a system, ensure that logical system names are correctly configured in the target system to avoid inconsistencies.
  
  If the issue persists after following these steps, it may be beneficial to consult SAP support or refer to SAP Notes related to logical system configuration and error handling.
