  The SAP error message APB_LAUNCHPAD142 indicates that unused system aliases have been removed from the system alias mapping in the SAP BusinessObjects (BO) environment. This typically occurs in the context of the SAP BusinessObjects Launchpad or when managing system aliases in the Central Management Console (CMC).
  Cause:
  
  
  Unused System Aliases: The error message is triggered when the system detects that there are system aliases that are no longer in use or referenced in the system. This can happen due to changes in the environment, such as:
  
  Deletion of reports or data sources that were previously associated with those aliases.
  Changes in the configuration or structure of the data sources.
  Manual removal of system aliases that are no longer needed.
  
  
  
  System Cleanup: The system performs a cleanup process to maintain optimal performance and organization, which includes removing aliases that are not linked to any active objects.
  
  
  Solution:
  
  
  Review System Aliases: Check the list of system aliases in the Central Management Console (CMC) to identify which aliases have been removed. You can do this by navigating to the "System Aliases" section in the CMC.
  
  
  Recreate or Update Aliases: If you find that certain aliases are still needed, you may need to recreate them or update the existing ones to ensure they are correctly mapped to the required data sources or reports.
  
  
  Check Dependencies: Ensure that all reports and data sources that rely on specific system aliases are correctly configured. If any dependencies are broken, you may need to update the reports or data sources to point to the correct aliases.
  
  
  Documentation and Maintenance: Maintain documentation of your system aliases and their usage to prevent confusion in the future. Regularly review and clean up unused aliases to keep the system organized.
