Link Group Data Fields

Link Group data fields can be edited on the Link Group Grid View in the Object Groups Grid or on the Link Group Property Sheet.

The following table describes all the data needed to define a Link Group.

Further information, including units details, about all the Network Object fields stored in the Master Database can be found in the data fields topics listed in the Network Data Fields topic.

Fields that are common to the majority of objects can be found in the Common Data Fields topic.

The Property Page column shows which page of the property sheet displays the data. The pages are:

1. Object Group Definition Page

2. User Page - see Common Data Fields topic for details of user fields

3. Hyperlinks Page - see Common Data Fields topic for details of hyperlinks fields

4. Notes Page - see Common Data Fields topic for details of notes fields

The Grid column tells you if the data item is available for editing in the grid view.
