15ABAP Programming for SAP HANAimplement the code pushdown. This section will conclude with an example thatshows a case in which code should be pushed down.15.4.1 How to Find Custom Code that Needs to Be Pushed DownLuckily for you, SAP has realized that you might need some help locating code tobe pushed down, and provides tool support for exactly this purpose. The toolsprovided to you enable an analysis of the SAP environment at your organizationand spit out a list of what sections of your custom code you need to have a lookat with a view to pushing down the code.There are three transactions working in tandem that enable this analysis:왘 The ABAP Test Cockpit (SATC)왘 The SQL Monitor (SQLM)왘 The SQL Worklist (SWLT)The ABAP Test Cockpit (which, as you’ll recall, was the subject of Chapter 4) doesa static check of your custom code in the development system. SQLM is a transactionfor analyzing database calls in production; the results look just like ST05.The big differences are as follows:왘 ST05 is designed for a one-off analysis of a single program; this is designed foranalyzing everything in the system and holding on to that data for a protractedperiod (e.g., everything that happened in the system for a year).왘 This information can be retrieved from the development system via RFC.The last member of this trio is anothe r new transaction called the SQL Worklist(Transaction SWLT; Figure 15.9), which retrieves the production data from SQLMvia RFC. Then, coupled with a static analysis of the ABAP code via the ATC, TransactionSWLT gives you a ranked worklist of what routines could do with beingimproved generally and, once you’re co nsidering a da tabase migration, whatcode could do with being pushed down into the SAP HANA database.In a nutshell, ATC + SQLM => SWLT.Exactly how to go about the SWLT proc ess to hunt down code that could beimproved by moving to the database could fill up a book all on its own. Luckily,there has been so much written on this subject that you do not have to go huntingfar (see the “Recommended Reading” box at the end of this chapter for a startingpoint).682
Locating Code that Can Be Pushed Down 15.4Figure 15.9 Transaction SWLTATC/SQLM/SWLT AvailabilityThe ATC tool was made available in SAP NetWeaver 7.02 SP 12 or SP 5 of SAPNetWeaver 7.31, and comes as standard in SAP NetWeaver 7.4.The SQL Monitor is available as of SAP NetWeaver 7.02 SP 14 or SAP NetWeaver 7.31SP 9, and comes as standard with SAP NetWeaver 7.4. You also need the ST_PI plug-into be on level 2008, support stack 8.The SQL Performance Tuning Worklist comes with SAP NetWeaver 7.02 SP 14, SAPNetWeaver 7.31 SP 9, or SAP NetWeaver 7.4 SP 2.683
