Selecting Objects
When you start the ABAP Workbench with the Object Navigator, the system displays the last object list that you displayed. This also applies to new terminal sessions.
Procedure
To select any existing development object in the Object Navigator for further processing:
By default, this field is filled with the name of the last object that you processed.
If you want to see a list of objects you have recently used, choose 
and select the required entry.
Step 2 does not apply if you choose Application Hierarchy in step 1.
or press The requested object is displayed in tree form.
If the object you selected is itself an object list (for example a program within a development class), the tree display changes again and only the selected object is displayed.
In this case, you need to select the object again by double-clicking it.
In step 4, you can you can also open the required object by choosing Change from the context menu. The system opens the object in change mode.
Alternatively, you can open the object in a separate session in step 4. Choose the new function Display ® In New Window.
Result
When you open an object, the Object Navigator calls up the development tool associated with the object to display it. The object is opened in display mode. To switch to change mode, choose 
in the application tool bar.
If you choose an include, the Object Navigator starts the ABAP Editor and opens the include. If , on the other hand, you double-click on a GUI status, the system calls the Menu Painter and opens the status.
In each tool, you can use the Other Object menu function to select another object from the same or another category. If, for example, you have opened an include in the ABAP Editor, choose: Program ® Other Object to choose another include or a further object or component.
