Adding a New Field Value

If a value does not exist in a field list, and you need it, in many cases you can add the new value into the field using these steps:

Open a form and display the record where you want to add the field value.
Click in the field.
Select Edit > Add Value for Current Field.

This option is available only for business-data list fields When the option is available, the form that is used to maintain the values (records) for this field is displayed. A new record is added automatically.
Complete the fields for the new record.
Select Form > Close and Save Changes.

The original form is displayed again, with the new value inserted into the field.
