[16.0][ADD] l10n_th_account_payment_register_order

[kittiu]

By standard Odoo, from an invoice, user make payment by click on Register Payment which launch a Payment Wizard.

This module change Payment Register Wizard which was models.TransientModel into a permanent menu Payment Register models.Model

The way the payment works is still the same as before, but it gives extra benefits,

• By being a new stored documents, it now has states Draft/Paid/Cancel
• It is now possible to extend the document further, i.e., approval process.
• When payment is paid, this document keep tracks of reconciled invoices vs payments
• It is no possible to cancel the Payment Register (and set the payment to draft), and reconcile it back later

Configuration

To use the new persistent payment register document, go to Invoice Settings.

• Use Persistent Document on Inbound Payment - for Customer Invoices
• Use Persistent Document on Outbound Payment - for Vendor Bills

Usage example,

Create 2 invoices 100 USD, both has withholding tax 3 USD

Click Register Payment, now the Payment Register wizard become a new document by itself.

1. Amount auto deducted as usual = 200 - 6 = 194 USD
2. As Withholding Tax = 6 USD

User can chang, amount, change to multi deduct and add another deduct

Create Payment (1 payment). It is also possible to cancel it (payment will be set to draft and reconciled from invoices)

Re-reconcile the same invoice and payment again.

I think it is normal, because the Journal Entry is already created, and it won't allow changing Journal. @Nantikan23 The point is, the Journal Number is also ran. So I think we shouldn't change Journal.
