Can we have read-only or partial access to certain screens?

Admin - User Setup - Module Security

Screen access in DBA is completely modular (or "menu-level").  So, either a user has full access to a screen (such as the entire Jobs screen) or no access at all to that screen.  There is not a way to give partial access to a certain module.  You can provide menu access to screens such as our Sales Order Inquiry and Job Inquiry which provide a great deal of read only information.  Our data views are also a practical way to get read only data.
