At the next level of granularity, you can compare changes from one transport of source code to another.
You usually transport ABAP code much less frequently than you save it in the ADT. Therefore, comparing transported code versions shows changes over a much longer period of time than the local change history does.
A new editor window opens, showing the currently open code in the Local: view. The saved code version is shown with its time stamp in an adjacent view.
Changes are highlighted in the two windows. Locations or changes are shown as icons at the right edge of the saved code version.
