Named filters are "fixed" combinations of filtering criteria, based on many of the columns you see in the table. They are selected using the View drop-down list. Named filters are created, edited, saved, shared and deleted by users. Additional options include:
This field can be a column filter - This extra checkbox displays for many of the filter columns shown in the Edit a Filter dialog.
If checked, the filter selections you've defined for that column can be changed dynamically within the table, just like any other column not specified by the named filter.
If blank, the filter selections you've defined for that column cannot be modified in the table. The column filter option doesn't display for this column in the table, preventing you from making any changes to it. Leaving this checkbox blank reduces confusion, since you can be confident that the named filter settings have not been modified by any additional column filtering you may have performed.
Similar to/Like - The text entered occurs anywhere within the target cell. Entering wild card characters is not necessary. For example, filtering a column by text that contains age will display records with the following cell values: age, agent, storage, etc.
Not Like/Is Not Assigned - The text entered occurs nowhere within the target cell.
Assignees and Pools - Filtering by assignee includes all pools an assignee is a member of. Filtering by Any Assignee shows all tickets assigned to either an assignee or pool. Filtering by No Assignee shows unassigned tickets.
If you have a named filter that specifies a service desk, then the service desk for that filter is selected in the service desk drop-down list.
If you have a named filter that does not specify a service desk, then the named filter still applies when you switch service desks using the drop-down list.
If you have a named filter that specifies a service desk, and then you change the service desk in the service desk drop-down list, the other filter criteria for that named filter still apply, but the View combo box shows No Filter.
