I'm looking at EDI for the first time.  I've made a test mapping of an 850 message. It just so happens that the file has a bad part number in it.  I was going to just delete it since it is a test.  But, ED-C tells me that I can't delete it until I convert to an SO.  During conversion I get a error message that it can't convert with the bad part number - go to ED-C to delete it.  I realize I can probably just fix the part number and that a real 850 probably won't have the problem.  I just wanting to bring it up in case I'm missing something obvious and someone could point out a way to delete lines.
