Use this table to define an unlimited number of custom fields and assign them to group tabs (see Tabs Table).
Line Number Field
This field cannot be edited directly. Dragging and dropping lines in the table automatically renumbers them. This number determines the order from top to bottom in which custom fields are displayed in records.
Select a group tab for the custom field. Up to ten custom fields can be assigned to the special "--Record Header--" group. These fields appear in the header of records rather than on its Specifications tab.
