Creating global fields
Global fields are display-only fields. BMC Remedy AR System server has two types of global fields:
- Regular global fields — Share data across multiple windows and forms. See Creating regular global fields.
- Window-scoped global fields — Share data across multiple records in the same window. See Creating window-scoped global fields.
To make a field a global field, you set the field ID to a value within a reserved range (see To create a regular global field and To create a window-scoped global field).
The following types of fields can be global fields:
- Selection (drop-down list, radio button, or check box)
- View (window-scoped global fields only)
You cannot create default values for global fields. The values in global fields begin as NULL until active links initialize them or users enter information into them. The values in global fields are not affected if users select Edit > Clear All or Edit > Set to Defaults.
For more information about display-only fields, see the description of Entry Mode under Field Properties.
In forms viewed in a browser, global fields are implemented as encoded values in cookies, which have a 4 kilobyte limitation. (With other cookie data, you can estimate that 3,500 bytes can be stored.) Global values are checked and fields are updated when a window receives focus.
