Hi @MonikaS9010, In this case it seems you are trying to open a instance which doesn't exist like there is a line1 item but this line1 might be your primary key . Primary key value which is "Radio colony " i guess not exist inside DB . that is why its throwing the error of line1 . Please try to give the correct primary key value and remove all below properties it will open all the result as u pass primary key correctly.
