Hey there,
Didn't you post this same question multiple times already on this website and also on Stackoverflow website? I would recommend that you look into the solution proposed by another user on that Stackoverflow thread, as that seems to be the more viable option:
stackoverflow.com/…/developing-a-custom-receive-pipeline-with-flat-file-disassembler
Please do not repost this same question again on this site as you are cluttering the forum board, or else I will have to remove those duplicate posts, as I am a forum moderator here.
Thank you.
