If not all options are made available in the menu, check the following:

1. Perhaps you did not obtain proper license to use a certain module (see PANTHEON editions).
2. Perhaps you do not have proper document types set for a certain menu item (see Document Types settings).
3. Perhaps a user uses customized menu different from the one used by the user group. You can restore to the preset menu at will (see user-defined menu).
4. Perhaps you are not assigned appropriate authorizations for a specific menu option or register (see user authorizations).
