SAP Online Help (which is not in PDF files) can be printed only relatively complex and be found even sometimes as well. Therefore these PDFs are very helpful.
These PDFs cover nearly all topics of the 4.6C SAP Online Help, ordered in chapters and sorted alphabetical. They make the entrance to new topics you are not familiar with a lot easier.
(For germans: There is a german version out at SAP as well:
German SAP Online Help PDFs )
