How to remind people who have not participated in training to send them messages?

For example, use software to train all employees. If you are reminded that you have not studied, you can add a sign of training, or not participating in training, or learning, or learning in the employee training database, and then automatically print out a notice through these signs to inform those who have not participated in learning. People take part in the study in time, and provide learning assistance conditions and time and place.
