Manjunath,
For complicated or difficult words (long, technical etc.) I always prefer simple and understandable substitutes. So that understanding those are easy Image may be NSFW.
Clik here to view.
doesn't put too much load on the brain.
So to try and put simple, understandable answers / comments to your questions -
1. Is the document created must be innovative? or can we post any document related to particular topic in particular SAP module?
It can be any document related to that forum/space.
In the same lines as Jelena Perfiljeva but with slight difference - You should feel that it will add value e.g. help someone etc. etc.
2. For blog post, can we share personal experience? or it must be related SAP domain experience?
Definition: a blog is a Web page that serves as a publicly accessible personal journal for an individual.
Yes, you can share and you should share personal experiences!
