ABAP Development Tools for SAP NetWeaver (ADT) provides you with tools for comparing source code. You can see how code has changed over time. You can also compare code versions across ABAP projects (ABAP systems).
Differences are displayed in the compare editor. Here, you can edit and merge
changes. This enables you to take over single or all adoptions from one system to
another or from previous to the inactive version of the object. For more
information, look here Merging changes in the compare editor
. Additionally, you
can unlock objects or open them in their default editor through the context
menu.
