In SAP ABAP, delivering a seamless user experience is essential for efficiency. A popular requirement is to display the ALV report and the selection screen on a single view. This can be achieved using the Screen 100 and CL_GUI_ALV_GRID within a custom container inside a module pool program. By doing so, you integrate input and output areas into one screen, eliminating the need for navigating between screens and making your SAP UI more user-centric.

This method aligns with the latest SAP development trends such as:

interactive reporting
user-friendly interface design
embedded analytics
real-time data interaction
Using CL_GUI_CUSTOM_CONTAINER and CL_GUI_ALV_GRID, you define a custom control area for the ALV output while retaining the input fields at the top or side of the screen. With proper layout and screen design, you provide a single-screen transaction that promotes high usability and data-driven decision-making.

This approach is commonly used in S/4HANA environments where simplified UI and real-time data access are key priorities. For enhanced functionality, this screen can also support event handling, data refresh, and filtering logic, ensuring that the report updates instantly based on user input.
