One method is to connect to the data source again like it is a new data source and then replace the old connection in the workbook with the new one.
Hope this helps!
I have the same issue in Bex Query by adding new characteristic or keyfigure.
I tried on version 10.3.6 successfully adding a column just running refresh extract.
But the issues appears in version 10.4 or more, the new column does not appear while running refresh extract.
I have the exact same problem as Rajender. I just want to add a column to the existing extract of the SAP BW - Bex query. Is there already a solution for this issue? (Working with Tableau Desktop 10.5.2)
I tried replacing the data source with the same query, but if I do that my whole dashboard is going to be messed up. So that doesn't help.
Would be great to have a solution for this issue! Because I don't want to rebuild the entire dashboard everytime the Bex query is edited
