• What is the cause and solution for SAP error message /SCMTMS/UI_MESSAGES688 - Transport not possible; unsaved changes exist ?

  The SAP error message /SCMTMS/UI_MESSAGES688 indicates that a transport operation cannot be completed because there are unsaved changes in the system. This typically occurs in the context of SAP Transportation Management (TM) when you attempt to perform a transport operation (like releasing a transport request) while there are unsaved changes in the relevant data.
  Cause:
  
  Unsaved Changes: The most common cause is that there are changes made in the user interface that have not been saved. This could be changes to a transport request, a shipment, or any other object within the TM module.
  Session State: If you have multiple sessions open, changes made in one session may not be saved before you attempt to perform a transport operation in another session.
  Data Integrity: SAP enforces data integrity rules, and unsaved changes can lead to inconsistencies if a transport is executed.
  
  Solution:
  
  Save Changes: Before attempting the transport operation, ensure that all changes made in the current session are saved. Look for a "Save" button or use the keyboard shortcut (usually Ctrl + S) to save your changes.
  Check Other Sessions: If you have multiple sessions open, check each one for unsaved changes. Save any changes in those sessions as well.
  Refresh the UI: After saving, refresh the user interface or navigate away and back to the relevant screen to ensure that the system recognizes the saved state.
  Review Transport Request: If you are working with a transport request, ensure that it is properly configured and that all necessary objects are included and saved.
  Log Out and Log In: If the issue persists, logging out of the SAP system and logging back in can sometimes resolve session-related issues.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any specific patches or updates related to this error message. Sometimes, there may be known issues or bugs that have been addressed in later releases.
  User Authorization: Ensure that you have the necessary authorizations to perform transport operations. Lack of proper authorizations can sometimes lead to misleading error messages.
  System Logs: Review system logs (transaction SLG1) for any additional error messages or warnings that may provide more context about the issue.
  Documentation: Refer to the SAP Help Portal or specific documentation for SAP TM for more detailed information on transport management and related processes.
  
  By following these steps, you should be able to resolve the error and successfully perform the transport operation.
