Custom Field

Every form in ERPNext has a standard set of fields. If you need to capture some information, but there is no standard Field available for it, you can insert Custom Field in a form as per your requirement.

You can go to Customize Form and add the Field in a particular Form or a Document type (hereafter referred to as DocType) .

To access Custom Field, go to:

Home > Customization > Form Customization > Custom Field

You can also go to the list view of any DocType and select Customize from the Menu options.
