I cannot open my database sheet, but the pivot sheets shows data extracted from database

hello. I cannot open my database sheet, but the other sheets shows the data. Get the error: “Can’t open PivotTable source file”

For exemple I have the A database sheet. B and C pivot sheets show the data extracted from the database.

But my database sheet is empty. What can I do to recover (to see) my database again?

Is it the database registered?

I find the answer.

If your pivot table has a Grand Total Row, double click on Grand Total Value, it will create a new sheet with a table having the whole data set for you, this will be an exact copy of the database.
