Where can you define a rowLevelSecurityFilter?

Defining a row-level security filter is primarily concerned with controlling access to data at a granular level, based on certain user attributes or roles. The correct context for implementing row-level security typically centers around how data can be secured according to user permissions or attributes.

Metadata is crucial because it contains information about the data set, including the security requirements for accessing that data. By defining a row-level security filter within the metadata of an external data file, you can specify exactly which rows of data a specific user or group of users can access, based on their characteristics. This ensures that sensitive information is protected and access is granted only to those who need it based on defined criteria.

The other options do not accurately describe where row-level security filters are typically defined. While reports and global security settings may relate to data accessibility, the specific implementation of row-level security is most effectively managed through the data's metadata, where it clearly aligns with the data's structure and access rules.
