An error has occurred when restarting the data import.
You can restart cancelled imports using the IMPORT command. To enable you to do this, when the Loader executes the command, it writes a restart file containing the name of the last table to be imported successfully.
This error occurs if the Loader is unable to find the name of the table written to the restart file in the assignment file. One possible cause may be that the assignment file was modified after the import was cancelled.
If possible, restore the assignment file to its original state. If this is not possible, you need to export and import all the data again to ensure your data is consistent.
