Currently, Windchill Quality Solutions Enterprise Edition supports the displaying of images files (*.jpg and *.bmp) and Microsoft Word document files (*.doc and *.docx) in the output of the Report Designs. Adding support for displaying of Adobe PDF files would allow an additional attachment file type to be automatically included in the output Report Design PDF file so that the attachment PDF file does not have to be added in after the Report Design is generated, saving an additional step.
