Grant SELECT privileges on that specific view to both the IFSSYS and IFSPRINT database users — GRANT SELECT ON <view_name> TO IFSSYS; and GRANT SELECT ON <view_name> TO IFSPRINT; — then try ordering/previewing the report again. Custom or non-core views used in a report layout need both of these grants for the report engine and the printing service to actually query them, which core application views already carry by default.
