Please mark this Discussion with a Correct Answer (closes, but does not lock the Discussion) and Helpful Answer where appropriate. Seehttp://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.
