What is the purpose of the 'Omit' field in Qlik Sense?

The 'Omit' field in Qlik Sense serves a specific function related to user data access. Its purpose is to specify a field that should be excluded from a user's data model. This allows for fine-grained control over the data that individual users can see, effectively customizing their data experience by omitting certain values from specific fields based on user attributes.

When implementing security in Qlik Sense, utilizing the 'Omit' field is crucial for ensuring that sensitive or irrelevant information is not presented to certain users, thereby adhering to security and privacy protocols. This functionality is particularly useful in applications that are accessed by various users with different data access requirements, allowing for tailored data visibility based on user profiles.

In contrast, including all user data, defining user roles, or granting access to restricted data serves different purposes and do not align with the specific function of the 'Omit' field. The correct option highlights the role of the 'Omit' field in managing user-specific access to data within the application.
