As a bi-product of the new report scheduler, it is now possible to get the parameters from the request form with the return value from RUNREQUESTPAGE function. Its possible to call EXECUTE (Processing only reports) and PRINT with parameters. So we do not have to create crazy constructs to handle parameter to automated reports.
Another new great feature in NAV2015 reporting, is the SAVEAS function that can return the report as XML data. (And save to streams also)
