Looking at several posts and comments there seems to be a lot of confusion about which SAP NetWeaver release is compatible with the new ABAP Development Tools for SAP NetWeaver (ADT). And I completely agree, it's not that obvious that the version of some core components differs from the corresponding SAP NetWeaver release identifier.
Coming back to the compatibility of ADT the most important components are the ABAP language, the ABAP runtime environment and the development infrastructure. ADT requires at least an AS ABAP with SAP Kernel 7.20 and SAP BASIS 7.31 with support package stack 04. This can easily be checked using SAP GUI:
Navigate in the menu to System -> Status and click on the Component Information button:
After verifying the SAP BASIS release close this window and hit the Other Kernel Info button:
Now, which SAP NetWeaver releases include an AS ABAP containing these component versions? The answer is:
The following SAP NetWeaver releases (onwards) are compatible with ADT:
- SAP NetWeaver 7.3 including Enhancement Package 1, Support Package Stack 04 [NW 7.31 SP04]
- SAP NetWeaver 7.0 including Enhancement Package 3, Support Package Stack 04 [NW 7.03 SP04]
I hope this clarifies most of the questions regarding the compatibility of ADT.
