Abap Performance Tuning
Dear Friends,
I'm got this error while use the Extended Program Check in particular z-programs where ever Im using the Z-package how can I avoid this error in Extended Program Check
. Program: ZCM_NO_SER_NITOR Include: CM_LES_CON_MISC Row: 68 [2]
Object PROG ZCM_NO_SER_NITOR has insufficient authorization to use objects
DTEL CMT_LS_CAC_POC from package CM_FS_CHGE_NCEL
ZCM_NO_SER_NITOR in package ZLMA
CMT_LS_CAC_POC in package CM_FS_CHGE_NCEL

I didn't see Properly!!! I spend 10-12 hrs of my day on SOLMAN forum. Z-Package Package ZLMA does not have sufficient use access how does it sound like???
Do you think there will be much response on this ABAP questions in this forum??
Why can't you make use of ABAP Development Forums?
Extended Program Check, simple search in ABAP forum would have provided you the solution.
Hope I am correct. Still if you argue that this is the correct forum.... I am damn sure you will get very delayed response that also doubtful.

Performance tuning for Data Selection Statement
For all entries
The for all entries creates a where clause, where all the entries in the driver table are combined with OR. If the number of
entries in the driver table is larger than rsdb/max_blocking_factor, several similar SQL statements are executed to limit the
length of the WHERE clause.
The plus
Large amount of data
Mixing processing and reading of data
Fast internal reprocessing of data
Fast
The Minus
Difficult to program/understand
Memory could be critical (use FREE or PACKAGE size)
Some steps that might make FOR ALL ENTRIES more efficient:
Removing duplicates from the the driver table
Sorting the driver table
If possible, convert the data in the driver table to ranges so a BETWEEN statement is used instead of and OR statement:
FOR ALL ENTRIES IN i_tab
WHERE mykey >= i_tab-low and
mykey <= i_tab-high.
Nested selects
The plus:
Small amount of data
Mixing processing and reading of data
Easy to code - and understand
The minus:
Large amount of data
when mixed processing isnt needed
Performance killer no. 1
Select using JOINS
The plus
Very large amount of data
Similar to Nested selects - when the accesses are planned by the programmer
In some cases the fastest
Not so memory critical
The minus
Very difficult to program/understand
Mixing processing and reading of data not possible

Tools available in SAP to pin-point a performance problem
The runtime analysis (SE30)
SQL Trace (ST05)
Tips and Tricks tool
The performance database
Optimizing the load of the database
Using table buffering
Using buffered tables improves the performance considerably. Note that in some cases a stament can not be used with a buffered table, so when using these staments the buffer will be bypassed. These staments are:
Select DISTINCT
ORDER BY / GROUP BY / HAVING clause
Any WHERE clasuse that contains a subquery or IS NULL expression
JOIN s
A SELECT... FOR UPDATE
If you wnat to explicitly bypass the bufer, use the BYPASS BUFFER addition to the SELECT clause.
Use the ABAP SORT Clause Instead of ORDER BY
The ORDER BY clause is executed on the database server while the ABAP SORT statement is executed on the application server. The datbase server will usually be the bottleneck, so sometimes it is better to move thje sort from the datsbase server to the application server.
If you are not sorting by the primary key ( E.g. using the ORDER BY PRIMARY key statement) but are sorting by another key, it could be better to use the ABAP SORT stament to sort the data in an internal table. Note however that for very large result sets it might not be a feasible solution and you would want to let the datbase server sort it.
Avoid ther SELECT DISTINCT Statement
As with the ORDER BY clause it could be better to avoid using SELECT DISTINCT, if some of the fields are not part of an index. Instead use ABAP SORT + DELETE ADJACENT DUPLICATES on an internal table, to delete duplciate rows.

if hlped pls mark points -
What measures shall we take if it is needed to performance tune the SAP Server. It is getting too slow. It will be helpful if someone can send me some link about SAP Performance tuning, not ABAP performance tuning.
Regards,
SubhasishThe SAP Servers can be slow because of many reasons:
1. The Table Consistency: The tables should be consistent. A consistency check should be done regulalrly.Better would be using DB13 so that it can be scheduled in appropriate days.
2. One major reason that I have found in recent times is the amount of authorizations that might be available to the users of the sytem. If all the users have a high volume of authorization objects in their user master buffer, then the response time becomes sluggish.This is true for most of the dev boxes that allow almost any amount of authorization for users and have a low RAM size.
3. Also you might be intrested to check your network consistency. If you are accessing your servers from home with a wireless connection of 16kbps, you might want to configure your logon pad for such a crappy connection.
Most of the BASIS performance tuning tasks such as ST04, STAT, ST02 and DB12 should be carried out too just to investigate furthur.
Hope these were a few helpful tips.
Peace be with everybody

Performance Tuning - Suggestions
Hi,
I have an ABAP (Interactive List) Program times out in PRD very often. The ABAP run time is about 99%. The DB time is less than 1%. All the select statements has the table index in place. Actually it isprocessing all the Production Orders (Released but not Confirmed/Closed). Please let me know if you have any suggestion.
Appreciate Your Help.
Thanks,
Kannan.Hi
1) Dont use nested select statements
2) If possible use for all entries in addition
3) In the where addition make sure you give all the primary key
4) Use Index for the selection criteria.
5) You can also use inner joins
6) You can try to put the data from the first select statement into an Itab and then in order to select the data from the second table use for all entries in.
7) Use the runtime analysis SE30 and SQL Trace (ST05) to identify the performance and also to identify where the load is heavy, so that you can change the code accordingly
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/5d0db4c9-0e01-0010-b68f-9b1408d5f234
ABAP performance depends upon various factors and in devicded in three parts:
1. Database
2. ABAP
3. System
Run Any program using SE30 (performance analys) to improve performance refer to tips and trics section of SE30, Always remember that ABAP perfirmance is improved when there is least load on Database.
u can get an interactive grap in SE30 regarding this with a file.
also if u find runtime of parts of codes then use :
Switch on RTA Dynamically within ABAP Code
*To turn runtim analysis on within ABAP code insert the following code
SET RUN TIME ANALYZER ON.
*To turn runtim analysis off within ABAP code insert the following code
SET RUN TIME ANALYZER OFF.
Always check the driver internal tables is not empty, while using FOR ALL ENTRIES
Avoid for all entries in JOINS
Try to avoid joins and use FOR ALL ENTRIES.
Try to restrict the joins to 1 level only ie only for tables
Avoid using Select *.
Avoid having multiple Selects from the same table in the same object.
Try to minimize the number of variables to save memory.
The sequence of fields in 'where clause' must be as per primary/secondary index ( if any)
Avoid creation of index as far as possible
Avoid operators like <>, > , < & like % in where clause conditions
Avoid select/select single statements in loops.
Try to use 'binary search' in READ internal table. Ensure table is sorted before using BINARY SEARCH.
Avoid using aggregate functions (SUM, MAX etc) in selects ( GROUP BY , HAVING,)
Avoid using ORDER BY in selects
Avoid Nested Selects
Avoid Nested Loops of Internal Tables
Try to use FIELD SYMBOLS.
Try to avoid into Corresponding Fields of
Avoid using Select Distinct, Use DELETE ADJACENT

Performance tuning in Smart form
Hi,
How to performance tuning in Smart form level
Any tips available kindly send me any one .
Thanks&Regards,
MayaHi,
If you are using a customized print program to call the Smart Form...it is better to fetch most of the data as much as possible within it and pass it useing form interface/functional module interface.
Then in the ABAP code where ever used, fallowing the ABAP coding performance tuning options like avoiding the MOVE-CORRESPONDING, INTO CORRESPONDING, using binary search for READ statement...etc...

hello friends,
i am supposed to use ST05 and SE30 to do performance tuning,and also perform cost estimation,
can some plz help me understand, i am not that good at reading large paragraphs, so plz donot give me links to help.sap
thank you.Hi
Se30 is the runtime analysis
Here it will give you detailed graph about your program .
abap time,database time application time ..
st05 is sql trace where it will give you individual select stmnts in your program
and also proper index is being used or not.
Other performance tips
check any select stmnts inside the loop and replace with read statement
use binary search in read stmnts
use proper index in where condition in select stmnt.
if you want to execute st05..go st05..trace on-execute ur program--come to st05..trace off and --list trace...
you get summary details of select queires and it will be pink or other color.

Performance Tuning for ECC 6.0
Hi All,
I have an ECC 6.0EP 7.0(ABAPJAVA). My system is very slow. I have Oracle 10.2.0.1.
Can you please guide me how to do these steps in the sytem
1) Reorganization should be done at least for the top 10 huge tables
and their indexes
2) Unaccessed data can be taken out by SAP Archiving
3)Apply the relevant corrections for top sap standard objects
4) CBO update statistics must be latest for all SAP and customer objects
I have never done performance tuning and want to do it on this system.
