Edit Link Templates
Occasionally after creating a link template, you may want to edit it. For
example, you might decide to add an additional key field or remove an
existing one. You also may need to update a link template if any changes are
made to the data source it points to. For example, you might rename a data-
base table or move it to a different location.
Note You can only change the key fields of link templates that don’t have any
links defined in their associated drawing. Changing the key fields of a link
template invalidates its links and breaks their association to the database table.
To edit a link template with links already defined, you must first delete all links
based on the link template from its associated drawing.
Edit Links
After you have created links, you may periodically need to update their key
field values. For example, you might change the numbering scheme for a
group of offices, or reallocate some rooms from the accounting department
to the sales department. You can use the Link Manager to enter new key
values for a selected link. The key values must reference a record that already
exists in the source database table.
To create a link template in the current drawing
1 In the dbConnect Manager, in the tree view, right-click a data source file.
2 On the shortcut menu, click New Link Template.
3 In the New Link Template dialog box, enter a name for the link template
in New Link Template Name, and then click Continue.
