SAP NetWeaver 74

SAP NW 7.4 is basically successor of NW 7.0x and particularly NW 73 not just from general SAP Application Server - ABAP stack point of view but it comes with many features with regards to HANA. Reason being is that the NW 74 got optimized for the HANA. This doesn’t mean that other databases are not supported. Sure they are just focus of optimization is just HANA. The NW 74 is foundation of Business Suite and all its innovations of 20013 and BW 7.4.

The NW 7.4 is available since May 2013. Currently there are following SP of NW 74:
SAP NetWeaver 7.4 SP0 GA May 2013
SAP NetWeaver 7.4 SP2 GA May 2013
SAP NetWeaver 7.4 SP3 GA July 2013
SAP NetWeaver 7.4 SP4 GA November 2013
SAP NetWeaver 7.4 SP5 GA December 2013
SAP NetWeaver 7.4 SP6 GA March 2014
SAP NetWeaver 7.4 SP7 GA June 2014
SAP NetWeaver 7.4 SP8 GA September 2014 – so called Service release SRS2
SAP NetWeaver 7.4 SP9 GA November 2014

So now let’s have a look what new is available in NW 74, of course majority of them are focused on HANA. A list below is gathered on NW 7.4 SP8:

-      “Code to data” ABAP code paradigm: This means that instead to do complex or data intensive operations on ABAP application server the logic is moved one floor down to database means to data layer. There are many new ABAP statements available to support this approach. Following are techniques to support this: ABAP Managed Database Procedures (AMDP), Native SQL (ABAP Database Connectivity (ADBC)), Open SQL enhancements for building views for CDS, Optimized protocols (Fast Data Access), Table buffer enhancements, Core Data Services (CDS) etc.

-      Development environment in Eclipse: basically all the development (not only in ABAP but UI and HANA development) can happen now in one tool – the Eclipse. Means co-development and deployment of HANA and ABAP artefacts.

-      Components like Application List Viewer (ALV) and Business Rules Framework (BRF+) optimized for HANA: e.g. ALV optimized for HANA (ALV on HANA), these components are directly leveraging power of HANA, e.g. result set or help displayed in drop down boxes for ALV is reduced already in DB by code-to-data approach.

-      SAP Gateway and SAPUI5 functionalities out of the box: systems based on NW 74 are ready for exposing its data via SAP Gateway using SAPUI5 user interface.

-      Majority of NW 74 offerings available in SAP Cloud Appliance Library (CAL): from the CAL the SAP system can be easily deployed from variety of preconfigured Rapid Deployment Solutions (RDS).

-      New developer tools e.g. for testing, monitoring: SQL Performance  Tuning Worklist (SWLT), ABAP SQL Monitor (tcodes: SQLMD, SQLM)
