Performance Check and Analysis Tools for SAP ABAP Interview


 Performance Tuning in SAP ABAP is required to write quality programs which reduces time consuming execution of SAP applications .To achieve this programming performance check ,there is available Analysis Tools which are used to check program performance .Tools are Run time analysis ,Performance trace ,Code Inspector ,Dump analysis and Extended program check .As a ABAP'r we should have well knowledge on all performance tools to face the real time SAP ABAP interview as experience consultant.

1.Run time Analysis (SE30)


We use this tool to analyse the performance of ABAP programming.We use the results of the run time analysis to identify:

          Run time-intensive statements.
          To show the hierarchy of program calls.
          Excessive or unnecessary use of modularization units.
          CPU-intensive program functions.
          Inefficient or redundant DATA BASE access.

2.Performance Trace(ST05)

       
We use this tool to record :
                                                 Data Base access,
                                                 Locking activities,
                                                Remote calls of reports and Transactions and Table buffer calls from the SAP system in Trace file and to display the performance log as a list.


Also in analysing individual trace records in detail.Here four traces are available.
                                                 1.SQL trace analysis.
                                                 2. Enque trace analysis.
                                                 3.RFC trace analysis.
                                                4. Table buffer trace analysis.


3.Code Inspector(SCI)


We use this tool to check SAP repository Objects .
It checks:The performance,
                Security,
                Syntax and naming conventions of the the individuals or sets of repository Objects .
            
And also,we use this tool to define inspections which examine the object sets with help of check variants.

4.Extended Program Check 

We use this tool to perform static checks which are too time consuming for the normal syntax check and it returns both errors and and Warning.


5.Dump Analysis(ST22)


We can use  ABAP dump analysis  to list the ABAP runtime errors that have occurred in an ABAP system as well as the relevant short dumps.


Displays and analyzes update statistics again
Save in a local file
Print
Store for a longer period of time

And also ,some transactions are available SAT and ST12 used to do SAP ABAP programming .So from this post ,we have learnt the some important Analysis tools on which we will face interview questions while we are facing real time ABAP interview.So in the next ,we will learn more ABAP interview Tips .
