I am following these IDoc creation steps.
IDOC Steps - ABAP Development - SCN Wiki
I have tried to ignore the BD64 step and run the program, I found I still success in creating an outbound IDoc.
So what is BD64 used for?
And is it a way to distribute communication IDoc directly by skipping the Message Control?
If I want to go through Message Control to distribute an outbound IDoc, how can I do it?
