• What is the cause and solution for SAP error message XT668 - System &1 and &2 access a common transport directory ?

  The SAP error message XT668 indicates that two or more systems (denoted as &1 and &2) are trying to access the same transport directory. This situation can lead to conflicts and inconsistencies in the transport management system (TMS) because multiple systems should not share the same transport directory.
  Cause:
  The primary cause of this error is the configuration of the transport directory in the Transport Management System (TMS). If multiple SAP systems are configured to use the same transport directory, it can lead to issues such as:
  
  Conflicts in transport requests.
  Inconsistent transport logs.
  Potential data corruption.
  
  Solution:
  To resolve the XT668 error, you should ensure that each SAP system has its own unique transport directory. Here are the steps to address the issue:
  
  
  Check Transport Directory Configuration:
  
  Go to transaction STMS in the SAP GUI.
  Navigate to the Transport Management System configuration.
  Check the transport directory settings for each system.
  
  
  
  Modify Transport Directory:
  
  If you find that two systems are pointing to the same transport directory, you will need to change the configuration.
  Each system should have its own transport directory path. You can do this by editing the transport profile of the affected systems.
  
  
  
  Update Transport Profile:
  
  Use transaction RZ10 to modify the transport profile parameters.
  Update the DIR_TRANS parameter to point to a unique transport directory for each system.
  
  
  
  Restart Transport Management:
  
  After making changes, restart the transport management system to ensure that the new settings take effect.
  
  
  
  Test the Configuration:
  
  After the changes, perform a test to ensure that the transport requests can be processed without errors.
  
  
  
  Related Information:
  
  Transport Directory Structure: The transport directory typically contains subdirectories for different types of transport requests, such as cofiles and data.
  Transport Management System (TMS): TMS is a tool in SAP that manages the transport of objects between different SAP systems (e.g., development, quality assurance, production).
  Best Practices: It is a best practice to maintain separate transport directories for each SAP system to avoid conflicts and ensure smooth transport operations.
  
  If you continue to experience issues after following these steps, consider consulting SAP support or your system administrator for further assistance.
