Dear Madhuri A
Jignesh Mehta sir is wright
As per My knowledge if you activated High risk ... And you are creating delivery W/O Sales order system will not block the Delivery Document until and unless You activate Delivery check and PGI Check.
In case imagine you have forgot to do this settings and created delivery .. and billing system wont update the credit limit so after realizing you have to run this program RVKRED77 OR RVKRED07
So any one comment if i am wrong
Thanks a lot
