SD-Q, System Manager, Configuration settings is where you set up the option to be able to save screen settings on all the programs.  From the Help:  
 
Configuration Settings
This setting controls whether the settings on selection screens for various forms throughout the system can be changed.  A blank or 0 means that no settings can be changed and program default settings will always be used.  A value of 1 means that a system wide set of defaults can be established but user-specific settings will not be available.  A value of 2 means that system wide defaults can be established but user specific settings can also be maintained on each workstation and will override the system settings.  The actual settings are established in the programs themselves such as SO-B  Print Acknowledgements  
Password
If the configuration settings are set to 1 or 2, this password will be necessary to make changes to the system wide configuration settings.  If the password is left blank, any user can change the system wide configuration settings.  Individual user settings at the workstation do not require the password and can be changed by each user at any time.
