There are two distinct levels of error handling during Smart Instrumentation preprocessing. First are the fatal errors that lead to termination of the import and rollback of all changes. The second type of error is only visible in the protocol file. For example, single positions cannot be imported because some data is missing. If this occurs, details are written to the log file. Set the message level (A.60.61) to 5 to see important warnings and errors for Smart Instrumentation. If you set it to 10, you will get more output, and with level 20, you will get all information that is provided concerning the Smart Instrumentation section.
