I have always been not just a fan but an advocate for SW, but lately I'm quite pissed about one thing in particular. The BOM in SW is very unstable. Excluded items my come back, part with not keep the same item number (EVEN WHEN I LOCK BOM NUMBERS), Description change, I have never really had a huge problem with this before, but when using routing which will probably be another post, it's a disaster. Comments? Recommendations?
