I don't believe you can set an manually defined page size. However, if you go to Page Setup you can
- Turn on "No Printer"
- Change the "Paper Size" - the highest this will go is "Maximum 11.7 x 17.7"
This will not affect how the report is generated in BO. However, users will not be able to print the report unless they have the correct size paper. They could, however, export to Excel, reformat the data, and print from there.
