Thanks for your reply. Unfortunately neither user education nor DB
can be applied in such situation. The rollback mechanism is suppose to protect from a invalid data loading process. In the system users are able to load
data from a file into DB. The most frequent error is that the file can include
incorrect data (although the file structure and relations between data can be correct).
