About Creating Custom Fields
When creating a field, determine the need for the field. Based on the form, think about what kind of additional data the field should store and the field type (for example, text, numeric, date, or month).
Once you define the field requirements, use VA Custom Fields Wizard to create the field.
The links below cover tasks related to creating custom fields, but do not cover the entire process of creating a new custom field. For more information, press F1 in any field in the Custom Fields Wizard to access help on that field.
