The original tables are in your Temporary tab of your Tables Panel. Access the Tables Panel as follows:
- Click the Worksheets Icon .
The Worksheet Panel will display either the Worksheet List or the Tables List.
- If the Worksheet List is displayed, click the Tables List icon .
- Click the Temporary tab.
- Find the table you are looking for within the list, and check its checkbox.
- Click Add to Worksheet.
The table you are looking for will have the same name as the current version, but a previous number. Note that the temporary tables from before your edit will still be related as they were prior. It may be constructive to add the previous final table to your Worksheet. Then you can use the original dataflow's Dataflow Graph to find any table within that dataflow.
