Import purchase history
I am trying to import our purchase history using the built in .CSV import tool, however when I import purchase.order it sets the PO to a draft invoice. I do not see an option to set them as done - other than validating the invoice and receiving the products (which I do not want to do). I am not interested in having any accounting associated with this, I want the past POs in the system purely as reference.
The user should be able to see the past purchases of a product (purchase.order.line) - This works fine.
The user should be able to view all historical purchase orders (purchase.order) set to done - at the moment when I import a PO it is always set to draft.
The user does not need to see the invoices, accounting or stock moves - these POs should be purely for reference.
How can this be done?
Edit - Should I be importing supplier invoices and lines rather than purchases?
