• What is the cause and solution for SAP error message CNV40107019 - Check for old and new Logical System are same ?

  The SAP error message CNV40107019 indicates that there is an issue with the logical system configuration during a data migration or conversion process. Specifically, this error occurs when the system detects that the old logical system and the new logical system are the same, which is not allowed in the context of the operation being performed.
  Cause:
  The primary cause of this error is that the logical system name for the source (old) and target (new) systems is identical. This situation can arise during data migration or conversion processes where the system expects to differentiate between the source and target systems, but both are configured with the same logical system name.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Logical System Configuration:
  
  Go to transaction code SE03 (Transport Organizer Tools) or SCC4 (Client Administration) to check the logical system names configured in your SAP system.
  Ensure that the logical system names for the source and target systems are different.
  
  
  
  Modify Logical System Name:
  
  If you find that the logical system names are the same, you will need to change one of them. This can typically be done in transaction BD54 (Maintain Logical System) or through the relevant configuration settings.
  Make sure to update any related configurations or settings that reference the logical system name.
  
  
  
  Re-run the Migration/Conversion Process:
  
  After ensuring that the logical system names are different, re-run the migration or conversion process that triggered the error.
  
  
  
  Check for Custom Code or Configuration:
  
  If the error persists, review any custom code or specific configurations that might be enforcing the same logical system name. Ensure that there are no hardcoded values or assumptions that could lead to this conflict.
  
  
  
  Related Information:
