Normally, when a menu calls the standard request submission form, that form can list the reports and concurrent programs contained in the report security group for the current responsibility.
Alternatively, you can assign a code to a request group so that a customized standard submission form only displays a list of concurrent programs contained in that particular request group. A request group code is simply an argument that is passed from a menu to a customized standard submission form. To summarize:
Request group codes provide a form-based method of controlling user access to concurrent programs and reports.
A code can be assigned to a request group.
You can use the code as an argument passed from a menu to the standard submission form.
When a menu that calls the standard submission form uses the code, that form lists only those programs in the request group identified by the code.
