Your boss has brought you the first set of problems that need to be addressed in your application. First, in situations where the last reports of the day aren't able to be entered until the following day, the hardcoded date string in the filename is a problem. The data entry staff need a way to manually choose which file they'll be appending to.
Also, the data entry staff have mixed feelings about the auto-populate features in the form. Some find it very helpful, but others would really like to see it disabled. You'll need a way to allow users to turn this feature on and off.
Finally, some users have a hard time noticing the status bar text at the bottom, and would like the application to be more conspicuous when it fails to save data due to errors.
