If you plan to add specific information such as header/footer to each page in the PDF, you may have to write custom Java code leveraging iText library. This library is shipped with Pega. For examples on how to do it using iText, you can check iText documentation online.
Thanks for your input. I am unable to find iText classes. Is it shipped with Pega or needs to be added externally? What is the quick way to check if its available on the system(I don't have Db access to difficult to check engine tables for classes)
