I need some help. If I create a Report with a Matrix Tablix (with row Groups and column groups) in landscape layout and preview it in print layout, the report generates me some extra empty page every 2nd page. I don't understand the rule, why it's doing that. My Report settings are: PageSize: width: 29.7 cm, height: 21 cm InteractiveSize: width: 29.7cm, height: 21 cm Margins : 0cm,0cm,0cm,0cm Report Body : widht: 25cm, height: 10cm According my Report settings this shouldn't happen, should it. The width of my Tablix is max 22cm. What I noticed is, that when I shrink the width of my Report Body to 21 cm (to the width of the portrait layout) or less, the emtpy pages disappear. Or when I delete the column group, it also renders the report without some empty pages. I think this problem has something to do with column groups. Is this a bug or am I missing a setting?
