Hello,

We made a migration from V8 to V10 few months ago.

On the new database (V10), we removed the accounting Apps and reinstall them to start from scratch about accounting.

Now when i'm creating a new invoice (supplier or customer) a very old attachement is automatically attached the new created invoice.

When i'm searching in the model ir.attachement with res_model  = "account.invoice", i can't find any attachement which are not yet linked to an account.invoice.id.

When i'll create a new invoice, the old attachement will automatically appear in ir.attachement model (with date of creation in 2014 for example).

Do you know how i can show and delete ir.attachement not linked yet to an invoice ?

Thanks

Morgan
