It is possible to add a different date in the sale order.

I use a script to do the import (because of migration), and use the date from the csv-fiel and place it in the field sale_order.create_date.

It might be that this field is not available when using the interface of openERP V7, or that it is overwritten by openERP when doing the CSV-import.

Let me know if you need some example of the script.

I work in OpenERP 6.1.1. I have many orders to import in Sales orders I found this "OpenERP - Se importan Lineas Order Sales desde archivo .csv" where in the right side I saw "Action - Importar Linea" would a big help for me. Thanks for help.
