Hi Sai Krishna,
It's easy, you have the option for downloading the notes in format PDF and you can save them with the name you want, because sometimes you don't have a quality access to internet, SAP marketplace doesn't work. The question is use strings as 'partner' 'credit' 'procedure' 'pricing' 'VKOA' 'VOFM' 'F110' 'VBFA' 'performance' 'NAST' and so on. You can search them with your windows engine in your PC. After some time, we know what are the strings more accurate for defining a problem. It's other skill we need and one reason to help others, because I can check this skill goes on working.
Regards
Eduardo
