Data relationships and the link file

Link maintenance involves establishing relationships between data so that information residing in one file can form the link query that selects, displays, or copies information from another file.

A separate link definition can occur for each form.

When a field is linked to more than one table, the order in which the entries appear in the link record determines the order in which Service Manager searches them. First, Service Manager searches the table at the top of the list. If no records are found to satisfy the link query, it searches the tables lower in the list, from top to bottom. It stops searching when the query is satisfied, or it finishes searching all tables in the list.
