exactly the title. I want to fetch customer’s purchase order from sales order when creating delivery note from sales order
The way i would do this is have a custom app or server script, that ties into the hook before_insert - The doc items will have a column called sales_order from that you can get the sales order doc and then the po number
is it solve? or still do you need help!
No need for custom logic, this capability is already in the system. If you added a PO number in the sales order, it carries over to all subsequent documents. You can find it under the “More Info” tab → Customer PO Details
Oh wow I didn’t pay attention to that
