What is the main function of a display column in Method 2?

• A. Stores a copy of linked data locally.
• B. Displays information from linked master files using a linkage record.
• C. Defines the base template layout.
• D. Performs data validation.

Answer: (B)

The main idea being tested is how a display column retrieves and shows information from related records using a linkage record. In Method 2, the display column doesn’t store another copy of the data; instead it uses the linkage to access the tied master file and pull the specific field to show in the column. This keeps data centralized in the master file and ensures the display stays up-to-date as the linked data changes. The other options describe functions (storing a local copy, defining a UI template layout, or validating data) that aren’t what a display column does.
