Thought I had this eConnect thing figured out, but alas.

 I want to generate SOP invoices and supply my own tax values, but that has become secondary at this point. Through repeatedly futzing around with my app, I've managed to get the interface to always return a "Subquery returned more than 1 value" error. I can cause the error to change by forcing erroneous data into the stream, like mismatching the subtotal and the total, but when I set them to something correct, I'm right back where I started.

I guess I've got something stuck halfway into the DB, but haven't got a clue what. Anybody seen this before?

BTW, this is GP8. I know, its backlevel, but those were the cards I was dealt.

I've got my tape monkey digging out the backup, just in case, but I sure wish I knew what went wrong.

Thanks,
