✅ My dataflow disappeared when I tried to undo my last operation

[JaneW]

I was in the dataflow graph window in Xcalar Design, and I wanted to undo the most recent operation I did, so I dropped the last table in the dataflow. But my entire dataflow graph disappeared! Did I lose all my work? How can I get it back?

Hi @JaneW,

Don't worry, your work isn't completely lost. You have only lost the virtual table you explicitly dropped and the operation immediately prior to the dropped table. The the table you want is either in your hidden or temporary table list. In addition, you may also find it as part of another active table's dataflow graph.

The only scenarios where a dataflow graph would disappear are:
1. if the previous table were used to produce another active table in your worksheet in which case it would be a temporary table
2. if you explicitly used "Hide Table" to prevent it from displaying a dataflow graph.

Take a look and let me know if you have any additional questions about this!

Best wishes,
Mark

Hi Jane,

For future reference, the best way to undo the most recent operation from within the dataflow window is to click on the table to the immediate left of the active table (the one resulting from the operation you want to undo) and select "revert to this table" from the pop-up menu.
