If you are asking how to put a custom container on your screen, the first create your screen by double clicking on the "100" in this line of code.
call screen 100.
Go in tht layout(screen painter). Click the ui element at the bottom of the screen on the left(second from the bottom). This is the custom control container, now click in the screen area and drap a container to the appropriate size. Now name it as ALV_CONTAINER.
