Why clicking Delete offers to remove table while you are in sheet view? How to undo deletion?

[ilazarevskiy]

I have accidentaly removed table from data model. Well, to be honest, it's wasn't accident. I tried to remove visualization from a sheet, and clicked delete button. Instead it offered to remove table from data model. Of couse I didn't read a modal window  (who would?) and clicked OK, and so, now I have lost a table along with calculated columns. How to restore it? (It is planned for deletion at next data load). Why is this even possible?

What you're describing seems very strange. To make any changes to the data model you need to reload the app data. No ways to remove a table from the data model without dropping it during load script.

If you delete only the visualization you can try to CTRL+Z to check if you can restore it, otherwise you have to contact your Qlik administrator to recreate it.
