What is the purpose of lookup filters?

1. To restrict valid values and results for lookup fields

2. To enforce field-level security

3. To create new object relationships

4. To manage API usage limits

The correct answer is: To restrict valid values and results for lookup fields

Lookup filters serve a specific purpose in Salesforce by restricting valid values and results for lookup fields. This means that when a user is selecting a record in a lookup field, the choices presented can be filtered based on certain criteria, ensuring that users only see records that are relevant to their context or that adhere to specific business rules. This feature enhances data integrity and improves user experience by guiding users to make appropriate selections. For instance, if you have a lookup field that relates a contact to an account, a lookup filter can limit the contacts shown to those belonging to the selected account, thereby preventing users from accidentally associating records inappropriately. In contrast, the other options address different functionalities that are not related to the purpose of lookup filters. Enforcing field-level security pertains to restricting access to certain fields based on user profiles, which does not involve filtering the lookup records. Creating new object relationships is about establishing new connections between objects, while managing API usage limits relates to tracking and controlling the resources and actions that can be performed via the API, none of which involve the lookup filter functionality directly.
