purchase_sale_inter_company

Automates intercompany purchasing so that a purchase order to a sibling company generates and keeps in sync the corresponding sale order and related documents in that company.

Features

purchase.order: Cancelling a purchase order cancels its intercompany sale when still a quotation and blocks cancellation once the sale has progressed beyond draft or sent.
purchase.order.line: Adding lines to a confirmed intercompany purchase also creates the corresponding sale lines unless the sale is cancelled or done.

sale.order: Confirming an intercompany sale writes the sale prices back to the originating purchase lines to keep costs aligned.
