I have a custom field : net_weight in Sales Order Item. I need it to populate from Item.net_weight. I have tried setting in the option box as follows: item.net_weight. However it is not picking it. Also note that this is a read only field.
Write above custom script in Sales Order.
It will fetch net_weight on selecting item_code in sales order item.
Thanks a million @kolate_sambhaji !! It works. I was trying it out in Sales Order Item earlier.
