When a system error occurs in an Invoice module, the system creates a new error log file. (Location and file name.)
The file contains:
The date and time when the error occurred
The error code and a description of the error
Often, a single problem may result in multiple errors. Each error is written to a separate error log file. When an error occurs, open and read all error log files that were created at the time of the error. Otherwise, you may miss important information.
Another type of error log is the crash report.
