Package Items

Platform elements that are included in a Package are known as package items.

This page details when items are included in the package, when they are installed in the target system, and when old items that have been removed from the source system are deleted from the target system, as well.

The information provided here is the foundation for the companion article: Choosing a Deployment Strategy for Development Systems

Standard Dependencies

When an item is selected for packaging, dependent elements are automatically included. Items that are related, but upon which the selected item does not actually depend are excluded by default--although they can generally be selected manually, if desired.

Platform Element	Dependent Elements
Application	Includes Application settings Includes all Custom Objects used in the application, along with their dependencies (see below) Includes all Global Picklists referenced by a field in an included object Includes all Classes that are referenced by a Business Rule or Macro Includes Dashboards that are visible to all, a Role, or a Team. (Does not include private dashboards.) Includes all Pages used in Dashboards, Web Tabs, and Sites, as well as all Pages invoked by an Action Button Includes all Application Reports that are visible to all or that are visible to an application Role. Includes all Roles used in the application Includes all Sites defined in the application Includes role-based Tab Preferences for objects Includes all Team definitions that are referenced in a Business Rule, Process, or Macro Includes role-based View Preferences for objects Includes all Web Services that are used in a Process, an External Lookup, an External Data Source, or a Business Rule Includes all Web Tabs defined in the application
Objects (Custom Objects and System Objects)	Includes all object settings and object relationships, including Record Locators Includes all objects that are the target of a Lookup Note: Does not automatically include objects that have a Lookup to the current object. If such Related Objects are not included in the package, any Related Information sections defined in object forms are automatically removed. Includes all objects that are encompassed by a Rollup Summary Field Includes Business Rules Includes Document Templates Includes External Data Source definitions Includes Forms, Layout Rules, Form Scripts, and Custom Form Actions Includes Fields and Field Scripts Includes Indexes Includes Macros Includes Processes Includes Validations Includes Web Forms Excludes Reports Reports can be individually selected. Reports on an object are not automatically included. Excludes data Data is not included automatically. Java code can be written to create Package Data classes that add selected records during packaging, and that take the records out when the package is installed.
Object data and other data (Package Data)
Classes (includes user-created classes)
Mapping Profiles
Pages
Reports
Sites	Includes Pages
Static Resources
Teams
Team Data Sharing Policies	Includes Teams and Roles involved Includes Child Teams if the Include Child Teams option is selected for that team
Translation Workbench	Includes localized labels and items
Web Services
Web Tabs	includes Pages, and any referenced Widgets (if available)

Special Dependencies

When the following elements are added to a package, the listed items are added as dependencies:

Team Data Sharing Policies

Roles and Teams included as dependencies

• If the Include Child Teams checkbox is enabled, the child teams of the selected teams in the Data Sharing Policy are added as dependencies

Objects in a Master-Detail relationship

Note: The "Master-Detail relationship" option on a Lookup field has been deprecated. This section is provided for legacy objects that have a Lookup field for which that option has been selected. Learn more: Master-Detail relationships If a Detail object is added to a Package, the Master object is added (automatically) as a dependent object If a Master object is added to a Package and if that Master object includes any Rollup Summary Fields, then the Detail object is added (automatically) as a dependent object When a Tenant installs a Package, the Rollup Summary Fields limit defined in Manage Tenant Capabilities is honored If the limit is exceeded, the installation process will stop and cannot proceed In order to complete the installation, delete existing Rollup Summary Fields to reduce the total number to within the defined limit After packaging, do not add or remove any Master-Detail relationships; doing so may cause unexpected results and/or loss of data

Items that are Never Packaged

These platform elements are never added to a package. Customizations made by the subscriber remain intact.

• Knowledge Base articles
• Knowledge Base categories
• SLAs

How Package Items are Applied

The principles that follow summarize the behavior of package items at installation time. Detailed tables list the behavior for individual items, following the summary.

Principles

• New items in the Package are added to the subscriber's system, while items with the same ID are replaced, or updated.

Note:

All aspects of an object (fields and forms, validations, and so on) are given a Globally Unique ID or GUID. Those IDs are preserved when the package is installed, which allows existing items to be replaced while new items are added. (When the overwrite option is chosen, items on the target system that do not have a matching GUID in the package are deleted.)

• If the subscriber created a new platform element with the same name as an item included in the package, the subscriber gets an error. (The error occurs immediately after they select the package. Installation is not allowed to proceed.)
• With few exceptions, modified items in the Package replace the versions that came from a previous Package.
  The exceptions are:

• Global Picklists -- Subscribers are expected to have added items and modified labels, so they are left intact.
• Email Templates and Quick Text -- These items are overwritten only if Overwrite Previous Package was selected by the publisher.
• Roles -- During installation, the subscriber has the option of merging or overwriting roles that are included in the package.

Note: Items that were added to the target system are never deleted. Items are deleted only when: (1) They were previously installed from the source system, (2) They were subsequently removed from that system, and (3) The Overwrite Previous Package option was chosen when the package was created.

Object Aspects

* Applies only to Cases object in the ServiceDesk application.

** View definitions are included only when they are visible to all, or to an included Role. Private views are not included.

*** Web Forms on objects other than Cases can contain two kinds of email templates--an auto-response template that

is sent to the submitter, and a notification template that tells internal users about new records. Unlike other email templates, they are always overwritten.
