I'm trying to import customer invoice with the template I've received with an export.

Here is my xls file :

partner_id/id                                __export__.res_partner_403

payment_term_id/id                    account.account_payment_term_net

invoice_line_ids/quantity               95

invoice_line_ids/product_id/id        __export__.product_product_3380_27c18c87

invoice_line_ids/id                            __export__.account_invoice_line_36206_0837b668

name                                                période test 5

I'm able to create a new invoice with it but with the field invoice_line_ids/id that use an existing id, it overwrites an existing invoice.

When I use the same file without importing invoice_line_ids/id, I get this error message: null value in column "name" violates not-null constraint DETAIL: Failing row contains (36221, 58, 2019-08-22 10:05:16.037967, 2019-08-22 10:05:16.037967, 58, null, null, null, null, 14877, null, null, null, null, 0.00, null, null, 3380, 10, 95.000, null, null, null, null, f, null). à la ligne 2

What is wrong in the file ? How can I import a new invoice ?
