Hi. A very interesting article. It describes the security on a table. I am interested to know if the same principal applies to folder permission. For example if I have folder A and folder b. I have two groups "all_users" and "report_writers" where report_writers is a subset of all_users. All_users has read only permissions and report_writers has read write access. All users_users has access to both folders and report_writers has access to folder B only. Will that work so the report writes can develop reports in folder b, and the rest of all_users can look at the reports developed in folder B.
