The new Create PDF functionality is available as an option on the Print button on any report request page that prints through the Role Tailored Client once the associated hotfix (KB 2628466) has been installed. Since this feature was added at the executable level, there is no code that needs to be added to each report to get this new functionality.
This functionality automatically enables the ability to have the report be printed as an Adobe Portable Document Format (PDF) document on the Microsoft Dynamics NAV 2009 server and then be downloaded to the RoleTailored client (RTC). The first time you execute this functionality you may be prompted with a dialog box asking you to Open/Save/Cancel the document with the option to "Always ask before opening this type of file.". If you uncheck the option then you will no longer be prompted to Open/Save/Cancel the PDF file.
Once you open the PDF file and assuming that Adobe Acrobat has previously been installed, then the PDF document will be automaticaly rendered. From this point, you can either save or print the document or print to the desired printer.
