Every time an import is carried out and data is imported into FleetWave a record is saved in the Import History table so, as a System Administrator, should you need to see details or get confirmation of an import being completed you can do.
The table can be found under the Import/Export menu item, and while you can't manually add records to this table, or edit existing records, you can archive and delete records when the history is no longer required. There is also an option on the browse table to delete the data that was imported, if, say, an incorrect file was imported. To do this, find the relevant import record in the table and click the delete icon on the row, then click OK on the confirmation popup.
Enter a record in view mode and it will show you details of the import, including which import definition was used, who performed the import, the date and time the file was imported, the name of the file that was imported, and the results of the import, i.e. how many records were added, updated etc.
