• What is the cause and solution for SAP error message 0T086 - &1 system(s) deleted that were unknown in TMS ?

  The SAP error message "0T086 &1 system(s) deleted that were unknown in TMS" typically occurs in the Transport Management System (TMS) when there is a discrepancy between the systems defined in TMS and the actual systems in the landscape. This error indicates that one or more systems have been deleted from TMS, but they were not recognized or were unknown to the TMS configuration.
  Cause:
  
  Manual Deletion: A system may have been manually deleted from the TMS configuration without proper synchronization.
  System Landscape Changes: Changes in the system landscape, such as the addition or removal of systems, may not have been properly reflected in TMS.
  Transport Directory Issues: Issues with the transport directory or configuration files can lead to inconsistencies.
  TMS Configuration Errors: Errors in the TMS configuration or transport routes can also lead to this message.
  
  Solution:
  
  
  Check TMS Configuration:
  
  Go to the TMS configuration (transaction STMS).
  Check the system overview and ensure that all systems are correctly defined.
  If a system is missing, you may need to add it back to the TMS configuration.
  
  
  
  Reconfigure TMS:
  
  If there are discrepancies, you may need to reconfigure TMS. This can be done by using the TMS configuration tool.
  Use transaction STMS and navigate to the "Transport Routes" and "Systems" sections to verify and correct any issues.
  
  
  
  Transport Directory Check:
  
  Ensure that the transport directory is correctly set up and that all necessary transport files are present.

  Check Logs:
