With the export to Excel function Qlik doesn't export the column total with a straight tabel. With the export of a pivot table the total of a dimension is exported.
Maybe a good idea to export the column total of a straight table. My customers are creating now their own totals in Excel and cost time.
I've got about 500 Qlik dual licencing users and you can bet that none of them understand why this issue hasn't been solved yet.
Qlik sense has three mayor issues qlik should focus on, export of totals in straight tables, cyclic groups and printing/pdf exporting when printing data exceeds screen area.
