Submitting the file
You can upload prepared CSV files through the application. The data is checked throughout the processes, and errors are highlighted. You must correct errors before the file is uploaded again. You can only transmit error-free files.
For larger files, you can log off the system while staying connected to the internet to allow the processing to continue. When logging back in, you will see either the submission error screen or the submission confirm screen.
