Dear @rmehta , thanks a lot for the help , I was able to find a workaround , I created a custom field and pulled the values in the child table fields manually from my custom script , but however the data in my custom field disappears if I save the document . Any help ? Please
With the help of the below script I am able to auto populate the item_code field in the stock entry module , cur_frm.add_fetch('prod_order','production_item','item_code');
prod_order is my custom field , my problem is the data entered in this field disappears while saving the document .
