I've been using Labview built in source code control (SCC) for a few months now, and after a few hardships, have pretty much got it working like I need it to. One thing I have noticed though, that I can't figure out, is this scenario: If I check out a vi, from SCC, and modify it by adding a new subvi to it, when I check it back in, the new subvi doesn't seem to get into SCC. Has anyone else noticed this? What might I be doing wrong? I would have thought that checking the vi back in would have been sufficient to get the new sub into SCC.
