These rules work in conjunction with Matching Rules to identify potential duplicates and determine what action the system should take.
When a user creates or edits a record, the Duplicate Rule evaluates the data against existing records using predefined Matching Rules. Matching Rules define the criteria used to compare records, such as matching on email address, phone number, company name, or a combination of fields. The Duplicate Rule then specifies what happens when a potential duplicate is detected.
Administrators can configure Duplicate Rules to take several actions. The rule can block users from saving the record entirely, ensuring no duplicates enter the system. Alternatively, it can allow the record to be saved while displaying an alert warning the user about potential duplicates. This flexibility lets organizations balance data quality enforcement with user productivity.
Duplicate Rules can be applied to Leads, Contacts, Accounts, and Person Accounts as standard objects. Each rule can compare records within the same object or across different objects. For example, a Lead Duplicate Rule can check for matches against both existing Leads and Contacts.
The reporting functionality associated with Duplicate Rules provides valuable insights through Duplicate Record Sets and Duplicate Record Items. These reports help administrators identify and merge existing duplicates in the database, supporting ongoing data cleansing efforts.
Key configuration options include setting conditions for when the rule should run, determining which profiles the rule applies to, and customizing alert messages users receive. Administrators can also specify whether rules apply to record creation, editing, or both scenarios.
Implementing effective Duplicate Rules is crucial for maintaining accurate analytics, ensuring reliable reporting, and providing sales and service teams with trustworthy customer information for their daily operations.
Duplicate Rules in Salesforce: A Complete Guide for Administrators
What Are Duplicate Rules?
Duplicate Rules in Salesforce are configuration settings that control what happens when users attempt to create or edit records that are identified as potential duplicates. They work in conjunction with Matching Rules to help organizations maintain clean and accurate data by preventing or alerting users about duplicate records.
Why Are Duplicate Rules Important?
Duplicate data is one of the biggest challenges organizations face with their CRM. Here's why Duplicate Rules matter:
• Data Quality: Clean data ensures accurate reporting and analytics • User Productivity: Users don't waste time searching through duplicate records • Customer Experience: Prevents embarrassing situations like contacting the same customer multiple times • Storage Optimization: Reduces unnecessary data storage costs • Integration Accuracy: Ensures data flowing to other systems is reliable
How Duplicate Rules Work
Duplicate Rules operate through a two-step process:
Step 1: Matching Rules Matching Rules define the criteria used to identify potential duplicates. They compare field values between the new or edited record and existing records in the database.
Step 2: Duplicate Rules Once Matching Rules identify potential duplicates, Duplicate Rules determine the action taken. Actions include:
• Allow: Let users save the record with an alert showing potential duplicates • Block: Prevent users from saving the record entirely • Report: Allow saving but log the potential duplicate for later review
Key Components of Duplicate Rules
1. Record-Level Security: You can enforce sharing rules to only compare records the user can see 2. Action on Create vs. Edit: Different actions can be configured for creating new records versus editing existing ones 3. Alert Text: Customizable messages displayed to users when duplicates are detected 4. Matching Rules Association: Each Duplicate Rule must reference at least one Matching Rule
Standard vs. Custom Matching Rules
Salesforce provides Standard Matching Rules for Accounts, Contacts, and Leads. These use fuzzy matching algorithms. Organizations can also create Custom Matching Rules with exact or fuzzy matching on specific fields.
Duplicate Rule Considerations
• Duplicate Rules run when records are created or edited through the UI, API, or data import • Up to 5 active Duplicate Rules per object are supported • Each Duplicate Rule can reference up to 3 Matching Rules • Duplicate Rules can compare across objects (e.g., Leads to Contacts) • Person Accounts are matched against Contact Matching Rules
Exam Tips: Answering Questions on Duplicate Rules
Key Concepts to Remember:
• Matching Rules identify duplicates; Duplicate Rules define what action to take • The Allow action shows an alert but lets users proceed • The Block action prevents record creation or modification • Cross-object matching is possible (Lead to Account, Lead to Contact) • Standard Matching Rules use fuzzy matching by default
Common Exam Scenarios:
1. Scenario-based questions: When asked about preventing duplicate Leads, remember you need BOTH a Matching Rule AND a Duplicate Rule
2. Order of operations: Matching Rules evaluate first, then Duplicate Rules determine the action
3. Limitations questions: Remember the limits - 5 active Duplicate Rules per object, 3 Matching Rules per Duplicate Rule
4. Cross-object scenarios: Questions may ask about preventing Lead creation when a matching Contact exists - this is supported
Watch Out For:
• Questions that confuse Matching Rules with Duplicate Rules - they are separate but work together • Trick questions about blocking ALL duplicates - remember users with bypass permissions can still create duplicates • Questions about Data.com - it uses the same duplicate management framework • Scenarios involving imports - Duplicate Rules do apply to Data Import Wizard and Data Loader
Best Practices to Remember
• Always test Duplicate Rules in a sandbox before deploying to production • Use the Allow action with alerts before implementing Block to assess impact • Run duplicate jobs to identify existing duplicates before activating rules • Consider creating reports on duplicate records for ongoing monitoring
