This creates a parent-child relationship between two fields, where the controlling field determines which values appear in the dependent field.
The controlling field can be either a checkbox or a picklist field, while the dependent field must always be a picklist or multi-select picklist. When a user selects a value in the controlling field, only the relevant options become available in the dependent field, streamlining data entry and ensuring data accuracy.
To set up field dependencies, navigate to Object Manager, select your object, and click on Fields & Relationships. Choose the dependent picklist field and click on Field Dependencies. Here, you can use the dependency matrix to map which dependent values should appear for each controlling value. The matrix displays controlling values in columns and dependent values in rows, allowing you to include or exclude specific combinations.
Field dependencies offer several benefits. They reduce user errors by limiting choices to only valid options, improve data quality by enforcing logical relationships between field values, and enhance the user experience by simplifying form completion. For example, a Country field could control a State/Province field, showing only relevant states when a specific country is selected.
Administrators should consider some limitations when implementing field dependencies. Standard picklist fields cannot be dependent fields, and you can only have one level of dependency per field. Additionally, each object can have multiple field dependencies, but complex scenarios may require validation rules or custom solutions.
Field dependencies work seamlessly in Lightning Experience, record pages, and Salesforce mobile applications, making them a versatile tool for maintaining clean, consistent data across your organization while providing users with an intuitive data entry experience.
Field Dependencies in Salesforce
What are Field Dependencies?
Field dependencies in Salesforce are a way to filter the available values in a picklist based on the value selected in another field. This creates a relationship between two fields: a controlling field and a dependent field. When a user selects a value in the controlling field, only relevant options appear in the dependent field.
Why are Field Dependencies Important?
Field dependencies are crucial for several reasons:
• Data Quality: They ensure users select only valid combinations of values, reducing data entry errors • User Experience: They simplify data entry by showing only relevant options, making forms less overwhelming • Business Logic: They enforce business rules at the field level, ensuring data consistency across records • Reporting Accuracy: Clean, consistent data leads to more reliable reports and dashboards
How Field Dependencies Work
Controlling Fields: Can be either a checkbox or a picklist field. The controlling field determines which values are available in the dependent field.
Dependent Fields: Must be either a picklist or multi-select picklist. The available values change based on the controlling field selection.
Key Rules to Remember:
• A controlling field can control multiple dependent fields • A dependent field can only have ONE controlling field • Standard picklist fields can be controlling fields but NOT dependent fields • Custom picklist fields can be either controlling or dependent • Checkboxes can only be controlling fields, never dependent • Multi-select picklists can be dependent but NOT controlling • You can create chains of dependencies (Field A controls Field B, Field B controls Field C) • The dependency matrix in Setup allows you to map which controlling values show which dependent values
Setting Up Field Dependencies
1. Navigate to Object Manager and select your object 2. Click on Fields & Relationships 3. Click Field Dependencies button 4. Click New 5. Select the controlling field and dependent field 6. Use the dependency matrix to include or exclude values 7. Save your configuration
Exam Tips: Answering Questions on Field Dependencies
• Know the field type limitations: Exam questions often test whether you know which field types can be controlling versus dependent. Remember: checkboxes and picklists can control, but only custom picklists and multi-select picklists can be dependent.
• Watch for standard vs custom fields: Standard picklist fields have limitations. They can control other fields but cannot be made dependent on another field.
• One controlling field rule: If a scenario describes multiple fields trying to control one dependent field, recognize this is not possible.
• Chain dependencies: Understand that you can create chains where Field B is both dependent on Field A and controlling Field C. This is a common exam topic.
• Page layout considerations: Both the controlling and dependent fields must be on the same page layout for the dependency to function properly. If a question mentions missing fields on layouts, this could be the issue.
• Record types interaction: Field dependencies work alongside record types. A picklist might have different available values based on record type AND the controlling field selection.
• Default values: When a controlling field has no value selected, the dependent field may show all values or no values depending on configuration. Pay attention to how questions describe default behavior.
• Look for keywords: Questions mentioning 'filtered picklist values,' 'dynamic options,' or 'conditional picklist' are typically referring to field dependencies.
