How to do the equivalent of pressing the "Transfer" button on a picking via OERPlib?

[pjmcdermott]

I have successfully created sales orders and confirmed them via OERPlib. I now have a set of picking operations and want to do the equivalent of pressing the "Transfer" button using a script.

On a sales order I can press "Confirm Sale" via oerp.execute('sale.order', 'action_button_confirm', [sales_order_id]).

But for a picking it appears to be more involved, as the transfer button pulls up a "Products to Move" screen, which allows for adjustment of the products and quantities moved.

I've tried reading the source code, and I am looking at openerp/addons/stock/wizard/stock_transfer_details.py and the do_detailed_transfer() method. But I am reaching the limit of my abilities to understand the Odoo code, beyond ascertaining that the tables stock_transfer_details, stock_transfer_details_items and possibly stock_picking are involved.

Can anyone help with the exact set of database entries I would need to do to created a correct transfer? I have a list of actually transferred products and quantities for the shipment, so the ability to modify the transfer from that proposed would be useful.

Thank you.
