Hi Guys,

I would like to share Comments on how client has given important preference for Performance on execution of transaction, Developments and Report.

What we can find through analysis from sap. How to get performance results in SAP for each execution and Back ground Jobs.

Transaction code for business transaction analysis is STAD.

Go to Menu bar Monitor –> performance—> Response time


Here you can get detailed analysis of Business transaction analysis

What we can find from business transaction analysis?

  1. Can easily find performance for each transaction on overall users or particular users.
  2. Can easily find performance for each Program.
  3. Can easily find performance for each back ground job for each user or overall.
  4. Can easily find from which server and Transaction and Program and user.
  5. Can easily find Response time and memory used in terms KB for each transaction and Program and user.
  6. Can easily find day by day how much memory using based on task types                    
  7. Can easily analyse how many calls per day based on task type or program.     
  8. Can easily find Work load overview

Through Transaction code: ST03N also we can analyse the performance for transaction.        

ST03N  is transaction to direcly check work load monitor analysis.

Generally we have to analyse three external activities which will get more performance issues           

  1. Transaction codes
  2. Reports
  3. Developments/ coding impact on running transaction and Reports.
  4. Having performance issues with Transaction execution and posting the Documents?         

Performance issue will get generally, because of huge records in Table level.

For example running MIRO transaction performance very slowly while posting and while checking the data. –    Why the performance issue rising in particular transaction and How to resolve it?                                                                                                                                                                                                                                                             

Solution: In standard tables there was lot of huge records and while running transaction, program calling dependent tables, which have more data. To avoid this we have to create secondary index in Table level by using ABAPer.

In SAP we have two indexes 1) Primary index and 2) secondary index.

  1. Using primary keys will create automatically primary indexes. Used for primary keys in table.
  2. Secondary should be create manually as per the user requirement.

Secondary index is help full to effective way of retrieving the data from data base tables.   

Index is like helping to you get easily data for your query.

It is not only use for Transactions, for reports also we will be create index. To generate the customized report with fast performance, Abaper will create indexes on dependent tables.

Please refer above link explained how to create secondary index in Transparent table.

  1. Having performance issues with Report execution and generating output?          

Sometimes based on selection screen – system will perform and will take to execute the report.

Arminda Jack explained clearly based on selection criteria the report performance get quickly. Thank you.

Please refer below link is explained standard report MB51 Performance improvement.

  1. Having performance issues with running of batch run for reports to get output? 

When we get query on this, first we have to look into whether this batch run related to standard report or customized report. Mostly reason for customized report is coding.

We have to look into mostly into coding part which have more loops and FM and call functions which will be impact on performance of report.

Please refer below link explained reduce run time of batch program

Hints: In SAP MM mostly will get performance issues in MIGO and MIRO. Why because there was huge records in standard tables like MSEG, EKBE, RBKP, and BSIP…

My humble request was if you are getting performance issue in MIRO, Please check first whether secondary index create in MSEG table or not.

Create secondary INDEX for MSEG table with the following fields as mentioned in note 413446 also.
Table MSEG: (Additional Index for CIN)
– Index: Index for reference documents.
MANDT
LFBJA
LFBNR
LFPOS

If doesn’t work you can check if you are using the duplicate invoice.
Putting an index on RBKP (see note 134660) and BSIP (see note 389359)
could greatly improve the MIRO performance.

If in case if you have still issues then ……

In order to analyse, we need to create SQL trace from transaction ST05 for the user that will use transaction MIRO. First hit ST05 and hit Trace on. Then go to MIRO (and complete the transaction).Go back to ST05 > SWITCH OFF Trace. Hit Trace List > Here you should be getting the trace results. Please provide result to SAP, the analyse of this. They would like to ask you to check which tables are involved (most time) in the process?

Normally the creation of secondary indexes for MSEG
should suffice for considerable performance improvement as this avoids
a full table scan of MSEG

Carla Bussolo explained very well on MIRO performance. Thank you..
