Hii Paarthiban,
You need to join two reports for ur requirement :
1. See below you have production order id, Production lot id and test extension field for which i have saved the value for prod order 351.
2. Here you have ref doc id which is Production lot id, & ur required field confirmation id.
You can Join both reports by Production lot id & then u will have the report just as ur requirement.
I don't think now u will have any difficulty to get the result.
Thanks & Regards,
