For almost every entry type there are policies to link 'child' entry types

These link panels are just the reverse of the WHERE USED policies of the child entry types. Here is an example for Application Groups with the policies to link Applications (APL) , Trigger (TRG) and Service Periods (SVP).

When you select one of these policy items, a list of entry names is shown as in Figure 2.

Entries which are already linked are shown with Status 'SELECTED'.

With action SELECT or ADD (or abbreviations S and A) the entries can be selected while with action REMOVE (or M) any selection can be reverted. It is also possible to make a single selection without scrolling via the command by entering the command SELECT or REMOVE with an entry name as parameter.

Usually multiple entries can be selected, but there are a few policies where only one linked entry is allowed, for example, the policy SERVICE PERIOD. For those policies always the last selection is taken. That means if an entry is already selected, and then another selection via the Action column is specified, then the indication 'SELECTED' for the already selected entry is removed automatically. And if multiple selections are specified in the Action column then the bottom selection is used.

Initially the displayed list is sorted alphabetically, but you can use the SORT command to get all selected entries to the top. The SORT command has the column name as parameter, so in the example above the command 'SORT STATUS' would move all selected applications to the top of the screen. The column can be abbreviated, so 'SORT S' would also move all selected names to the top, while 'SORT A' would show the applications again sorted alphabetically by name.

The SORT command is also available on the WHERE USED panels. On some of those panels, entries from different types are shown, for example, WHERE USED for Trigger shows Applications and ApplicationGroups. On these panels the command 'SORT T' would show the names sorted by Type and for each type sorted by name.
