How do I create a new field for my project and display it on JIRA screens?

[olaruh]

I need help with making some settings in:  Issues - Configure Field: "Business Analyst"

- Add new context

and 

Applicable contexts for scheme: Edit Configuration

                                                    Issue type(s):

                                     Default value: Edit Default Value

                                     Options: Edit Options

When you create a new field, you will get a selection of which screens you wish to associate the field with.

If you skipped this step ( it isn't mandatory ) then locate the screens that relate to your project and update them. At the bottom of the configuration window for each screen will be an 'select field' list. You can locate and add your new field here.
