Use this skipped records tab to see which items have been skipped, and add them back to the next sync run.
The items can be skipped from within the Preview tab. Some rows are linked and if one is skipped, then the other must also be skipped. For example if the invoice line is skipped then the invoice payment that is being exported to MYOB must also be skipped. Items are often skipped in the preview window when it shows an error that the user has to go and resolve. The user can also manually select to skip the items from the current sync when they know they are incomplete.
When you adjust the export from date forward, items in this tab that are earlier than the export from data will not be shown. This list only shows the items that are skipped in the current export from period.
