We need some data in the stock.picking module. The base document Sales Order can get the SO Number, but we also need some data coming from stock.picking.
I saw this question but no answer yet. https://www.odoo.com/forum/invoicing-5/accessing-stock-picking-from-invoice-184557
Do you want data from invoice on stock.picking or do you want data in sale order from stock.picking? Please clarify your question.
Oh sorry for confusion. From invoice we need some data coming in stock.picking.
