ABAP Programming for SAP HANA
implement the code pushdown. This section will conclude with an example that
shows a case in which code should be pushed down.
15.4.1 How to Find Custom Code that Needs to Be Pushed Down
Luckily for you, SAP has realized that you might need some help locating code to
be pushed down, and provides tool support for exactly this purpose. The tools
provided to you enable an analysis of the SAP environment at your organization
and spit out a list of what sections of your custom code you need to have a look
at 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) does
a static check of your custom code in the development system. SQLM is a transaction
for 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 for
analyzing everything in the system and holding on to that data for a protracted
period (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 SQLM
via RFC. Then, coupled with a static analysis of the ABAP code via the ATC, Transaction
SWLT gives you a ranked worklist of what routines could do with being
improved generally and, once you’re co nsidering a da tabase migration, what
code 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 be
improved 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 hunting
far (see the “Recommended Reading” box at the end of this chapter for a starting
point).
