Dictionary attributes alter the behavior of the table or field that the dictionary record describes. Administrators can add or modify dictionary attributes.

Adding an attribute

To add or remove an attribute to a table or field, open a dictionary record, select the Advanced link, and modify the Attributes field. Alternatively, in a dictionary record, select New in the Attributes related list. For details on modifying dictionary entries, see Modify dictionary entries.

Attributes are comma-separated. If attributes exist on a dictionary record, add a comma with no spaces before adding an attribute.

For an attribute that accepts true/false values:

  • To specify a value of true, you can either enter attribute or attribute=true.
  • To specify a value of false, you can either ensure that the attribute does not appear or enter attribute=false. To maintain the values during upgrades, do not remove an attribute that is on a table by default.

Maintaining attribute values for upgrades

If you remove an attribute that is part of the base system, it is automatically restored during an upgrade. To prevent upgrades from changing the behavior of your system, leave the attribute on the table or field, but set its value as desired.

For example, if a field has the attribute knowledge_search=true by default, do not remove the attribute to set it to false; rather set it to knowledge_search=false.

enforce_dot_walk_cross_scope_access

true/false

any table

This attribute enforces dot-walk cross-scope access restrictions for individual tables. The attribute must be added to the dictionary record for the table (the record in sys_dictionary with Type = “Collection” for the specific table).- To enable enforcement, add enforce_dot_walk_cross_scope_access or enforce_dot_walk_cross_scope_access=true.

  • To turn off enforcement, add enforce_dot_walk_cross_scope_access=false.

i18n_locale_text_match

true/false

any string field

If true, enables case and accent (diacritic) sensitivity for text search of the column. If false, text search of the column is case and accent insensitive. The default behavior is false. This attribute can't be set to true when i18n_session_language_sortable is true on the same column. To learn more see Set case and accent sensitivity on a per-column basis.

i18n_session_language_sortable

true/false

any string field

If true, enables sorting the column by the user's session language. If false, sorting by the user's session language is disabled and the column is sorted according to the English alphabet. This attribute can't be set to true when i18n_locale_text_match is true on the same column. To learn more see Sorting according to the session language

icons

name of JavaScript class

any workflow field

Specifies a JavaScript class that produces workflow icons.

ignore_filter_on_new

true/false

any field

If true, prevents the fields on a form from populating with values from a filtered list.

ip_data_control
  • none
  • canonical
  • expanded
  • canonicalize_when_possible (default value)

field type on any table

Checks whether the data should be normalized through the ip_data_control attribute. - If the attribute is none, no conversion happens and data is inserted as-is.

  • If the attribute is canonical, values are inserted in their smaller canonical form.
  • If the attribute is expanded, values are inserted in the larger expanded form to facilitate comparisons.
  • If the attribute is canonicalize_when_possible, values are inserted in canonical form when it is a valid IP or as-is when it is not.

isOrder

true/false

any field

Sets the field as the default field that is used for the sort order in lists. Overridden by the ORDERBY URL parameter, or the user's sort preferences.

iterativeDelete

true/false

any table

If present or true, forces all row deletes to execute iteratively. Otherwise, you can perform some deletes using a more efficient bulk method.

json_view

true/false

any table

if a JSON object is associated with the field, places an icon next to a field that, when you click it, displays the data interchange information.

knowledge_custom

name of JavaScript function

any field

Specifies a JavaScript function to implement a custom knowledge search (see knowledge_search).

knowledge_search

true/false

string fields

If present or true, causes a knowledge search icon (a small book) to appear next to the field. Clicking this icon launches a pop-up window for searching the knowledge base, unless a custom knowledge search function has been specified. To learn more, see knowledge_custom.

largeTable

true/false

any table

If present or true, marks this table as "large" to preventing table locking with specific MySQL database operations (adding/removing a column/index, compacting a table). Without this attribute (or the smallTable attribute), the glide.db.large.threshold property, or the default value of 5,000, determines whether a table is large.

listen

true/false

any field

live_feed

true/false

any field

If present or true, creates a toggle option on the activity formatter header for incidents, tasks, and problems. The toggle provides a choice between the Live Feed for that record (also known as a document feed) or the activity formatter fields already in use. To learn more, see Activity formatter for more details.

long_label

true/false

any reference field

Long or short labels refer to the label that appears for reference fields on a form. For example, if the reference field contains the caller’s email address, the long label would be Caller Email, while the short label would be Email.

  • Usually the placement of the reference field on the form makes it clear what the field represents.
  • It uses the global property (glide.short.labels) to specify the type of labels that appear for all reference fields on any form.
  • You can override the global property for any reference field by setting the short_label=true or long_label=true attribute in the dictionary for the reference field.

maintain_order

true/false

any glide_list

If present or true, the up/down arrow order buttons appear to the right of the list of selected items.Note: You need to use the Add multiple button to see the order buttons.

mode_toggler

true/false

any composite_name field

If present or true, causes a name mode toggle icon (a small right-pointing triangle) to appear to the right of the label. Clicking this icon causes the field's rendering to change from a text field that accepts <tablename>.<fieldname> to a pair of reference choice boxes (one for the table, the other for the field). The latter is the default.

model_class

binary Java class name

any field of type glide_var

Specifies a model variable within the Java code. The model must have a class that implements the IVariablesModel interface.

model_field

see description

any field of type glide_var

Identifies a reference field in the record that has the model defined for it. For example, a workflow activity is associated with an activity definition. The activity definition has a related list of questions that make up the model for that activity definition. By using the activity_definition as the model_field for the activity, it builds the workflow activity model by reading the questions that are defined for the referenced activity definition.

nibble_size

positive integer

any table affected by the table cleaner

Specifies the maximum number of records that the table cleaner can delete in a single operation. The default value for this attribute is 250.

nibble_sleep

true/false

any table affected by the table cleaner

If false, causes the table cleaner to perform cleanup operations without a pause between each operation.

no_add_me

true/false

any table

If present or true, hides the display of the Add Me icon that appears next to certain fields, such as the Watch List field.

no_attachment

true/false

any table

If present or true, prevents the attachment icon (a paperclip) from appearing on the form header.

no_attachments

true/false

any table

If present or true, attachments are not checked for and deleted when a record from this table is deleted. Meant for high-activity tables that never have attachments.

no_audit

true/false

any table

If present, this field is not audited, even if the table is being audited. The true or false value is ignored.

no_audit_delete

true/false

any table

If present or true, a sys_audit_delete record is never created when you delete a record from this table. Meant for high-activity tables that never need sys_audit_delete information.

no_auto_map

true/false

any table

If true, this field is not mapped during an import set. Primarily used for LDAP imports.

no_email

true/false

any glide_list field referencing sys_user

If present or true, the email box is removed from the glide_list field like the Watch list field.

no_multiple

true/false

any glide_list field

Hides the select multiple icons.

no_optimize

true/false

any table affected by the table cleaner.

If present or true, prevents the MySQL table compaction operation from running on the specified table. The table compaction operation typically runs after the table cleaner deletes at least 50 percent of the data in the specified table.

no_separation

true/false

any table

If present or true, marks this table as not participating in domain separation. To learn more, see Domain separation for service providers.

no_text_index

true/false

any field on a text indexed table, or any child table of a text indexed table

If a table is text indexed, the no_text_index field attribute prevents this field or child table from being included in the text index.

no_truncate

true/false

any string field

In a list view, shows the entire text value of the multitext value in a list, without truncating it. Without this attribute, the string is truncated based on the UI property Number of characters displayed in list cells which is 40 by default.

no_update

true/false

table

True for tables in which records are inserted or deleted but not updated. Prevents the system from creating sys_mod_count, sys_updated_by, sys_updated_on fields in the table when created. Does not stop updates of the table. This attribute setting is used to save space on high volume system tables, such as syslog and sys_audit.

no_view

true/false

any glide_list field

Hides the view-selected item icon.

omit_sys_original

true/false

price and currency type fields

When true, avoids retrieving the original value of a field during calculations. Omitting the sys_original value from being referenced during calculations can reduce performance issues when dealing with currencies or prices.

onlineAlter

true/false

any table

Tables with the onlineAlter attribute perform MySQL database operations using online schema changes. - Online schema changes provide a lock-free table upgrade when adding, modifying, or removing columns and when adding or dropping indexes. Without online schema changes, these changes to the database lock write access during execution.

  • Online schema changes use additional system resources. Oracle databases do not lock tables by default and do not use online schema changes.

order

numeric value

model variable fields

Used internally only (for model variables).

pop-up_processor

binary Java class name

any field or table

Specifies a custom pop-up processor for processing the field (or all fields in a table).

ref_ac_columns

list of field names separated by semi-colons

any reference field with an auto completer (see ref_auto_completer)

Specifies the columns whose display values should appear in an auto completion list, in addition to the name. To learn more, see the cmdb_ci field (Configuration Item) on the Incident form for a working example.

ref_ac_columns_search

true/false

any reference field with an auto completer (see ref_auto_completer)

Causes auto-complete to work with all fields that are specified in the ref_ac_columns attribute. This attribute overrides the default behavior, which searches only the display value column. To learn more, see Configure auto-complete to match text from any reference field.

ref_ac_display_value

true/false

any reference field with an auto completer (see ref_auto_completer)

Causes the reference field to hide the display value column so that the auto-complete function only matches the text from the columns that are listed in the ref_ac_columns attribute. This feature requires the use of the AJAXTableCompleter class and the ref_ac_columns, ref_ac_columns_search, and ref_ac_display_value attributes. To learn more, see Remove the display value column.

Note: The ref_ac_display_value function does not work with Catalog Item variables.

ref_ac_order_by

field name

any reference field with an auto completer (see ref_auto_completer)

Specifies the column that is used to order the auto completion list.

ref_auto_completer

JavaScript class name

any reference field (can be applied to a table to affect all reference fields on the table.)

Specifies the name of a JavaScript class (client side) that creates the list auto completion choices. Valid class values include: - AJAXReferenceCompleter: Matching auto-complete choices appear as a list. Only the Display values column of the reference table appears. If there is no other auto-completion class specified, reference fields automatically use this class.

  • AJAXTableCompleter: Matching auto-complete choices appear as rows in a table. The display value column of the reference table appears, with any columns listed in the ref_ac_columns attribute.
  • AJAXReferenceChoice: Displays matching auto-complete choices as a list. Only the display value column of the reference table, and up to 25 matching choices, appear. If there are more than 25 auto-complete choices, the choices for the AJAXTableCompleter class appear for the reference field instead.

For more information, see Auto-complete for reference fields.

ref_contributions

UI Macro name list, separated by semicolons (";")

any reference field

When the field renders on a form, it invokes the named UI macro.

ref_decoration_disabled

true/false

any reference field

When set to true, disables the display of the reference icon on a selected field.

ref_list_label

label text

any table

Specifies the title to use in a list banner.

ref_qual_elements

field name list, separated by semicolons (";")

any reference field with a reference_qual field

Specifies a list of fields to send back to the server to get an updated reference.

ref_sequence

list of fields in referenced table, separated by top hats ("^")

any reference field

Specifies the fields in the referenced table that are used to order the list. This attribute works like an ORDER BY clause in SQL, with each element in ascending order.

reference_types

list of valid reference types that are clickable separated by semicolons (";")

field_name field

Limits the reference fields that appear in the tree to the specified types.

remoteDependent

name of database and table (like "model.matcher")

any script field

Defines the remote (such as in another database) table that the script depends on.

repeat_type_field

field name

a repeat count field for schedule rotation

Specifies the field that contains the repeat type (daily, weekly, monthly, or yearly).

ro_collapsible

true/false

any multiline field

If present or true, causes an icon (either a "+" or a "-") to appear next to the field label, allowing the field itself to be expanded or collapsed.

saver_exempt
  • exempt_always= field will be skipped from writing to xml for all install contexts.
  • exempt_never= field will not be skipped from writing to xml (Default).
  • exempt_vcs_only= field will be skipped from writing to xml only in source control context.

Fields of metadata records

When present, determines if the field is written to the xml representation of the record. An absence of the attribute is equivalent to exempt_never. When exempt_always, the field is skipped from writing to xml when exporting (publish, commit to source control, update set). When exempt_vcs_only, the field is skipped from writing to xml only in the source control context.

scale

integer

decimal field

Sets the number of decimal places to use on a Decimal field type. The default is 2. This attribute is applied to the max length attribute setting for the field. The decimal places for a field are a combination of the max length attribute setting and the scale attribute. For example, if you want four decimal places for the field, you need a max length attribute setting of 4, plus the default of 15 or 19. You would set the scale attribute to 4 to indicate the number of decimal places. Six decimal places require a max length setting of 21, a scale attribute setting of 6, and so on.

Note: Increase the max length attribute to a value greater than 15 to increase this attribute.

script

a function that returns the contents of the field

any slushbucket field

Enables you to write a script to define what is loaded into the slush bucket field.

short_label

true/false

any reference field

Long or short labels refer to the label that appears for reference fields on a form. For example, if the reference field contains the caller’s email address, the long label would be Caller Email, while the short label would be Email.

  • Usually the placement of the reference field on the form makes it clear what the field represents.
  • The global property (glide.short.labels) specifies the type of labels that appear for all reference fields on any form.
  • You can override the global property for any reference field by setting the short_label=true or long_label=true attribute for the reference field in the dictionary

Defines the tables for which this field determines the start (open) time of an SLA.

sla_closure

list of table names separated by semicolons (";")

any field of date type (glide_date_time, glide_date, due_date, date, or datetime)

Defines the tables for which this field determines the ending (close) time of an SLA.

slushbucket_ref_no_expand

true/false

any reference field

If present or true, prevents users from expanding the field from a form or list slush bucket.

smallTable

true/false

any table

If present or true, marks this table as Small (that is, not large) for querying purposes. Without this attribute (or the largeTable attribute), the glide.db.large.threshold property, or a default value of 5,000 determines whether the table is large.

start_locked

true/false

any glide_list field

Determines whether the field is locked or unlocked by default. Set the value to false to unlock the field by default.

staticDependent

name of table

any script field

Specifies the table that the script depends on.

name of script include

table_name field

Specifies the name of a script include whose process() method returns an array of table names from which to select.

target_field

percent_complete_target decimal field name

any percent complete fieldany decimal field

Text
target_field=percent_complete_target,target_threshold_colors=0:tomato;50:khaki;90:lightgreen

Specify an additional target_field attribute to compare the actual completion percentage of a task with a target percentage in a different decimal field that specifies where the task should be at this point. Use the column name of the decimal field.

Example:

Text
target_field=percent_complete_target,target_threshold_colors=0:tomato;50:khaki;90:lightgreen,target_field=u_expected_completion

If you do not specify an additional target_field, a target value of 100 is used, allowing you to use the color thresholds with a single field value. See Target threshold colors attribute.

target_form

name of form

any table

Specifies the alternative form to be used when this table is referenced through a pop-up window on a reference field.

target_threshold_colors

  • For optimal performance, do not apply it unless it is required.

text_search_only

true/false

table_name field

Limits the tables listed to those tables that are searchable by text.

text_index_translations

true/false

any table

If present or true, forces indexes to be recalculated when translated strings are added. You must have a sys-admin role to modify this attribute. This one is automatically set for indexed fields that are translated, and to fields that have a translation and are being indexed. The glide.i18n.force_index system property, which defaults to true, overrides this attribute.

time_zone_field

name of field containing the time zone

any schedule date/time field

Specifies the field in the parent record that contains the reference time zone for this field.

timeDimension

true/false

any field of date type (glide_date_time, glide_date, due_date, date, or datetime) in a table subclassed from the task table

If present or true, enables the production of time dimension data for use by OLAP (to produce reports based on quarters, weeks, or other time periods). Note: OLAP functionality has been deprecated.

update_exempt

true/false

any field from a table that has update_synch set to true

If present or true, you can change this field without skipping updates to the rest of the record. During software upgrades, the value of this field is preserved, while the rest of the record receives upgrades. By default, the Active field on a tracked table is treated as update_exempt even if the attribute is not present.

update_synch

true/false

any table

Indicates that changes in the table are tracked in update sets. Administrators cannot modify this attribute. To migrate data, use an Importing from another ServiceNow instance.

use_document_viewer

true/false

any table

If present or true, enables users to open supported attachments in a document viewer within the platform, rather than downloading the files directly to their own file system.

use_workflow

true/false
