You allow a new user to sign-on to Oracle Applications by defining an application user. An application user has a username and a password. You define an initial password, then the first time the application user signs on, they must enter a new (secret) password.When you define an application user, you assign to the user one or more responsibilities. If you assign only one responsibility, the user, after signing on, immediately enters an application. If you assign two or more responsibilities, the user, after signing on, sees a window listing available responsibilities.All Oracle Applications products are installed with predefined responsibilities. Consult the reference guide for your Oracle Applications product for the names of those predefined responsibilities. Additionally, instances of the major components that help define a responsibility (data groups, request security groups, menus, and functions) are predefined for Oracle Applications.
