Hi Noboru,
If you have new questions, please post them each in a new Discussion.
Please mark this Discussion with a Correct Answer (closes, but does not lock the Discussion) and Helpful Answer where appropriate. See http://scn.sap.com/community/support/blog/2013/04/03/how-to-close-a-discussion-and-why Even if you discovered the solution without any outside contributions, it helps others to understand what the solution turned out to be.
Do not use Assumed Answered as it confuses anyone looking for the specific answer. If you dig into the Getting Started link (top right of each SCN page), you are only instructed to mark Helpful or Correct Answers to Discussion responses.
Thanks, Mike (Moderator)
