Register Payment keep amount

When you register a payment in Odoo (for example from an invoice or a bill), the Register Payment wizard normally recalculates the amount whenever you change the payment journal or other options. This module adds a small checkbox called keep_previous_amount right after the amount field on that wizard.

If you tick the checkbox, the amount you already entered is remembered and restored after the wizard recalculates. The amount is only kept when it is not zero, so an empty or zero amount is still recalculated normally. If the recalculated amount is different from the one you typed, the wizard puts your typed amount back.

• Appears in the Register Payment wizard form, next to the amount.
• Works on the account.payment.register wizard used for customer invoices, vendor bills and other accounting entries.
• No new menus, reports or scheduled actions are added.
• The checkbox is off by default, so behaviour is unchanged unless you use it.

This is useful when you want to pay a specific amount (for example a partial payment) and you switch the journal, without Odoo overwriting your figure.
