Bank statement problems for multiple payments for one invoice

[Vincent Renaville@camptocamp]

Hello,

We have found a problem and solution (I hope ;) ), for multiple paiement with a Bank statement for an invoice.

I will give you 2 uses cases that work like a charm, and one that cause the error:

1) You create an invoice of 1000 CHF
    You pay 200 CHF with a bank statement
    The amount to pay of the invoice decrease to 800 CHF
    You pay 800 CHF with a bank statement
    The invoice is paid/reconciled and the due amount is 0 CHF

2) You create an invoice of 1000 CHF
    You pay 600 CHF with a bank statement
    The amount to pay of the invoice decrease to 400 CHF
    You pay 600 CHF with a bank statement
    The amount to pay of the invoice decrease to -200 CHF and the invoice is NOT paid/reconciled

Now I will give you the use case that doesn't work

3) You create an invoice of 1000 CHF
    You pay 600 CHF with a bank statement
    The amount to pay of the invoice decrease to 400 CHF
    You pay 1000 CHF with a bank statement
    The invoice is paid/reconciled and the due amount is 0 CHF

This is an error, because we lost the previous paiement, the invoice must NOt be paid/reconciled, and the due amount must be equal to -600 CHF.
the probem is located in the Bank statement process, when you received a paiement equal to the invoice amount, it doesn't check if we have a previous partial paiement.

You will find a patch attach to correct the problem.

Thanks for your help,

Vincent
