I have a report with lot of columns. The page setup is set to landscape in Crystal Reports. If I export to pdf it exports in landscape mode. When I publish this to Infoview, it looks fine here as well. If I export to pdf, then it always appears in potrait and not landscape.
Could be your CMC settings for the object in Infoview but the Adobe PDF option doesn’t allow any special formatting.
It should take it as is. Probably best bet is to check the patch level of your installation and check whether there is a bug fix in one of the later patches.
