Thank you for link you sharing. But I think my post for this question is quite interesting one.
Because For this post , in fact I aware there are few solution , I can do the edit expression at field level , by recode the Filename to SG. I think this approach is not productive. And another way I need to using partial reload to change the value label , which will slow down reload as it will generate another table , imagine I have 100 table to load.
So I just hope some one can share with me any other approach which can be more productive.
