You need to have patience once you post and expect assistance as everybody is contributing in SCN voluntarily. Also, when you wanted to update something to your original post, add the same in "Comment" and not in "Answer".
Now coming to your post, sorry it is not clear. Where do you want to attach? Sales Documents ? Moreover, before posting did you search Google as attaching documents in SD has been discussed many times and you can take the inputs from there.
