Payment distribution does not match the Invoice Distribution when the invoice has negative distributions.
When using negative distributions, the invoice and payment distributions will not match. The negative amounts cause the expense to payable to recalculate based on percentage when creating the payment(s). The formula which calculates each positive invoice distribution's corresponding payment distribution is:
( Invoice line amount / total positive values ) * invoice amount = payment distribution associated with that line
If you would like your invoice distribution to match your payment distribution while including additional transactions, enter miscellaneous entries on the invoice.
