What is the purpose of a subreport?

• A. To run in a separate schedule only.
• B. To store a copy of the main report.
• C. To export to different formats.
• D. To reuse another report's data or layout within a parent report, enabling modular design.

Answer: (D)

Subreports are about building with reusable pieces inside a larger report. They let you embed one report into a parent report, so you can reuse the other report’s data definitions and layout within the new context. This modular approach means you design a component once and include it wherever needed, ensuring consistency and making maintenance easier because changes to the subreport flow through to every parent that uses it. It’s not about running on a separate schedule, storing a copy of the main report, or exporting to different formats—those aren’t the purpose of a subreport. The core idea is to reuse another report’s data or layout inside a parent report to create modular, scalable reporting.
