Hi Gregory,

Sounds like a good approach and it would not affect the existing records. The only problem that we have lots of tables and we're using Stonefield. I know how to write a program to update all tables automatically, but I'm not sure how to incorporate it with Stonefield. I'm going to discuss this idea in details with my colleague. Right now he decided to update framework to put some code to update these fields in Save method. However, it would not work for my case if I'm updating multiple tables at once. I found that field_a and field_b works, but I don't want to rely on this naming convention.

Thanks again.
