Every time SAP comes out with a new set of pdf manuals, the meta data has to be corrected. Often the stored titles, description, etc are wildly wrong. Very sloppy and unprofessional for a mega corp the size of SAP.
The ePub book format has been out for many years and has many features that make it tablet, phone, PC, whatever friendly. Reading a SAP manual at night? No problem, change the font color to white on black so you don’t wake your spouse. The font is too small? No problem, choose a larger or different font. You can’t do any of that with a PDF. Try reading the ASE Admin guides on a 4″ iPhone. I dare you. You might as well pour salt in your eye sockets.
