Doubts on XML Pólizas (Mexico)

Hello,

We're finding some problems when validating the XML file of "Pólizas", report R7009003. I wonder if someone has the same problems, how have you solved them?

1- The line of Poliza>Transacción>CompNal>MontoTotal can't be a negative amount, but for Credit notes (RM) the F03B11.AG are always negative. How have you solved it?

2- For Inventory adjustments with "0" amount, there's a line for "Poliza", but there's not a line for "Transacción", I guess that it is because on F0911, the amount is 0, but it gives an error on the XML file validator.

Maybe some of your clients have found those or other problems, please, add on this discussion you experience!
