SAP : Save Report Output to a PDF File

http://www.erpgenie.com/sap/abap/code/abap51.htm

This report takes another report as input, and captures the output of that report. The output is then converted to 
PDF and saved to a local file. This shows how to use some of the PDF function modules, as well as an easy way to 
create PDF files.
