OpenErp 6 gtk client : import a lines for purchase order

Question

I am currently in the process of entering purchase order lines in open erp.

Unfortunately, I have many lines to add on openerp 6 gtk, so I try the option import.

First, I made an export csv with field id product, product code, quantity. but it gives me the message:

Following columns cannot be exported since you select import compatible.
Order lines/product_id
Order lines/product_qty

thank you for your help.

Answer 1

Checked with Add Field Names instead of import compatible and than export file.

product_id is a many2one relationship. So rather export product id, export it's name.

Here is more details of import-export csv file.
