When transports are imported into an SAP System, then objects change in this system. If you are working in the system at the same time as these changes are occurring, which means different objects are being used, various (temporary) problems may arise.

Therefore we recommend not working with the system during the import. You must stop productive use of the systems during the import.

Take the following precautionary measures:

• Dialog users must log off or bring all sessions with the OK code /n to their initial screens.
• Do no let any background jobs run. Wait for any running jobs to end or terminate them. Ensure that only background jobs which are required by the import itself run during the import. You have to reset the schedule of other jobs that would cause new jobs to start during the import.

The following actions are not necessary:

• You do not have to lock new dialog users from logging on as long as they follow the procedure as described above.
• You do not have to restart the system after the import.
