To create a dependent field (i.e. Field Dependency):

• Login using an account that has 'Administrator' privileges.
• Click Settings on the top-right, and select Customize Accompa from the menu.
• In the resulting page, click  Configure dependent fields link in the "Customize Fields" section.
• In the page that appears, click  Add New Dependency link.
• Then follow instructions on the screen to create the field dependency (and thus the 'dependent field').

Once you create a dependent field as explained above - that field dependency will be automatically implemented in 'Add Requirement' and 'Edit Requirement' pages.
