Opening Development Objects
You can open an ABAP development object in the appropriate editor in several ways:
Starting from the Project Explorer
- By double-clicking the corresponding node of the ABAP project in the Project Explorer.
- By opening the context menu of the corresponding node in the Project Explorer and then selecting Open in the menu.
Based on the results of the global object search and where-used function
- By calling the Open ABAP Development Object dialog (Ctrl + Shift + A shortcut) and then selecting an item from the results list.

- By calling the where-used function for a development object or sub-object (Ctrl + Shift + G shortcut) and then selecting an item from the Search view.
Based on the results of various check runs (ATC, ABAP Unit Tests, and so on)
- By double-clicking an error or warning, or a task record that is associated with an object, from the Problems or Tasks view.
Starting from an open source code editor
- By using the standard navigation capabilities within the editor (such as F3).
- By choosing the icon
Open ABAP Development Object in the toolbar.
- By choosing Ctrl + click on the left mouse button on the name of the corresponding development object.
Note If no Eclipse-based tool is available for the selected development
object, the suitable tool will be opened in the SAP GUI.
Note For development objects from the Source Library, the function 
Open With 
SAP GUI 
in the context menu of the Project Explorer is at your
disposal. This additional option is required in certain individual cases only. If
you execute this function, the selected object will be opened in the SAP GUI tool,
which, in turn, means that the standard Eclipse-based navigation will be suppressed.
Keep in mind, however, that this function does not change the standard behavior;
opening the same object text again by means of double-click, for example, opens the
Eclipse-based source code editor.
