Account Payment Return Import

This module adds an import wizard to Odoo's Accounting app that lets you load payment return files received from your bank. You can find it under Accounting > Customers > Import Payment Return. The wizard accepts a single file or a ZIP archive containing multiple files, and it can automatically match the imported returns with existing payments if you leave the 'Match after import' option checked.

When you import a file, the system reads the bank account number from the file, finds the corresponding bank account in Odoo, and determines the correct bank journal. If the journal cannot be found automatically, you can select it manually in the wizard. Each imported transaction gets a unique import ID, and the system checks for duplicates: if a transaction was already imported, it is skipped and you receive a warning listing the ignored items.

The module extends the payment return form and search views to show the imported bank account, and adds a filter to group payment returns by that bank account. It also adds a new field on payment return lines to store the raw import data for debugging. The import process is designed to be extended by other modules for specific bank file formats, but it already supports a basic CSV format.
