[18.0][ADD] account_reconcile_sale_order

[hbrunn]

This module allows a workflow where you don't invoice sale orders until
you've received a payment.

That's useful ie for webshops with non-instant payment like wire
transfer, where you might have a lot of customers not doing the payment
after all, which results in extra work for cancellation of the
invoices/orders involved.

Configuration

To configure this module, you need to:

1. Go to Invoicing/Configuration/Reconciliation Models
2. Create a model of type Rule to match sale orders

Usage

To use this module, you need to:

1. Have a payment on a bank statement matching the amount of an
   invoicable sale order
2. Enter the reconciliation screen
3. Observe that the sale order is offered as reconciliation counterpart
4. You can manually select and deselect sale orders in the sale orders
   tab of the reconciliation widget

Note the reconciliation only works if fully invoicing the sale order
yields an invoice over the order's total amount. Usually this means that
all products in the sale order must have invoicing policy Ordered
quantities.

We are doing this in a PoC using payment.transaction, that creates itself a account.payment record, and when the invoice is created and validated, then the payment is auto-linked. I think it's the cleanest one.

[hbrunn]

is your PoC available somewhere? Though I don't see how what you describe matches the requirement outlined above: No accounting items created for SOs until payment received

Yes, I read bad the purpose of the module. The module name doesn't help either, although technically it makes sense.

We'll publish soon the other module. I'll ping you when done.
