OK, I think I see the difference here. Finally getting back to this adventure.
So, I realize I was saying that “deferred revenue” wasn’t working, and that was a very poor choice of words in hindsight. DR works fine for me. My problem was the sales account it was using.
REWIND. First difference is that I am using Service Contracts, and that’s not what the KB article is about. They are doing a misc invoice for a part sale. So their sales GL is typically from the product group or the company level.
My problem came from the service contract piece. I have a GL control on that, and I think I had set the sales and deferred revenue to the same account (stupid, I know now). But then I fixed it, and future contracts were amortized to the new accounts I chose (good), but old ones continued to be amortized with the old sales account (bad).
It’s all very opaque with amortizing a service contract. You just have to get it right the first time, or else.
