Open SAP GUI in separate window with AIE
Development Objects that are not integrated in eclipse with a native editor are opened with the workbench tool within a SAP GUI. The GUI is opened within an eclipse window. If you don’t like that behavior you can switch to the mode that the SAP GUI is opened in a separate window. You can switch the behavior via the eclipse preferences page under the item ABAP Development->SAP GUI Integration
