Packaging 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
