Steps to reproduce: Create Sale Order (line in step 1 product qty = 100, in step 2 line product qty = 1000) with two or more purchase procurements  and Cancel it.

Current behavior:

Expected behavior:

Order Canceled

Comment:

Error exist in line:

 price_unit = self.env['account.tax']._fix_tax_included_price_company(seller.price, procurement.purchase_line_id.product_id.supplier_taxes_id, procurement.purchase_line_id.taxes_id, self.company_id) if seller else 0.0

the problem is with value: self.company_id

should be: procurement.company_id

            )['total_excluded']
        if line.product_uom.id != line.product_id.uom_id.id:
            price_unit *= line.product_uom.factor / line.product_id.uom_id.factor
        if order.currency_id != order.company_id.currency_id:
