Creating a function group for an SAP ABAP table maintenance generator

I am trying to use an SAP ABAP table maintenance generator on a Z table. It's asking for an authorization group and a function group. What function group do I need to use here and how do I create it?

Using the SAP ABAP generator use SE80 to create the function group. I'd suggest one function group per table. Authorization groups can be created from within table maintenance (i.e., Menu Path: Environment > Authorization > Authorization Groups).
