Getting Runtime in code

tmin = 1000000.

DO 10 TIMES. GET RUN TIME FIELD t1. MOVE f1 TO f2. "Time measurement of the moveGET RUN TIME FIELD t2. t2 = t2 - t1.IF t2 <tmin. tmin =t2.ENDIF.

ENDDO. WRITE: 'MOVE 4000 bytes takes', tmin, 'microseconds'.

Summary

The Program Extended Syntax check is the simplest and least CPU-intensive analysis tool. It can be found from ABAP Editor by following the menu path: Program-> Check->Extended program Check.

The Runtime Analysis Tool lets you analyze the performance of any transaction or program created in the ABAP Workbench in more detail. An additional very valuable function of the Runtime Analysis tool is the Tips and Tricks. This lists coding tips and examples, which can be used to improve coding efficiency. (Transaction SE30)

You can use the SQL Trace tool to examine the database interfaces of reports and transactions. (Transaction ST05)

The Computer Aided Test Tool (CATT) is fully integrated into the ABAP/4 Development Workbench. It allows you to assemble and automate business processes in test procedures.

Questions

How do you measure runtime of a program? SQL TRACE allows you to see how OPEN SQL statements get converted to

EMBEDDED SQL. True or False?
