Displaying ALV using a Docking Container

Hello Friends in this article we are going to see how to display ALV using docking container in sap abap


This program is used to display Docking Container. Sometimes we get the requirement to place the container at any corner as resizable Ex:  ALV and selection parameters in same Screen. To serve purpose we will go for docking container.


As we know that a SAP Container is a control that accommodates other controls, such as the SAP Tree Control, SAP Picture Control, SAP Text edit Control, SAP Splitter Control, and so on. It manages these controls logically in a collection, and provides a physical area in which they are displayed. All controls live in a container. Since containers are themselves controls, you can nest them. There are five kinds of SAP Containers:

SAP Custom Container: display controls in an area defined on a normal screen using the Screen Painter. Class: CL_GUI_CUSTOM_CONTAINER

SAP Dialog Box Container: display controls in a modal dialog box or full screen.


SAP Docking Container: The SAP Docking Container allows you to attach a control to any of the four edges of a screen as a resizable screen area. You can also detach it so that it becomes an independent modal dialog box. Class: CL_GUI_DOCKING_CONTAINER

SAP Splitter Container: to display more than one control in a given area by dividing it into cells. Class: CL_GUI_SPLITTER_CONTAINER

SAP Easy Splitter Container:  this container allows us to divide an area into two cells with a control in each. The cells are separated by a moveable splitter bar.


Here we display the functionality of docking container.

SAP Docking container can be attached on or more areas of screen. To reattach the docking container to a different edge of the screen we use DOCK_AT method. To switch the status of the Docking Container between fixed (docking) and free (floating) we use the method FLOAT.

We can use docking container in web Dynpro and sub screen also.

Below is the Example of Docking Container.
