I have a database that is used by multiple users. It seems that some of the records are missing when two users are entering data at the same time.
I entered data on one terminal at the same time another user entered his. I finished the input and saved the recored. I then checked the table and my data was there. After the second user finished his entry, I checked the table again and ny entery was gone.
I've attached a copy of the database. The specific area was the "Scale Ticket" menu. Any selection from there does the same thing.
