Hi,
Check with the links,

BW statistics is for performance anylsis of the system. In tables RSDDSTAT* all information is stored how long a query took, how a long a loading process took and so on. With this information you can analyze which are your long running queries, the most performance taking actions and so on. This reporting is available in the web, in BEx by predefined queries. To be able to execute these queries you
have to activate technical content and load it regularly (on a daily basis). You can also setup the so-called BI Administrators cockpit. See help.sap.com or here in SDN for much more detailed information. The other way is of course
to visit class "BI Performance & administration".
You can install the BW statistics same as Business content. Go to Business Content tab in RSA1go to BW Statistics infoareacollect all the BW statistics Cubes and Multiprovider. Once it is done you can load data and can able to report on
them.

BW Statistics:we have a option to activate BW statistics in BW 3.x version in AWB->tools->Activate BW Statistics
In BI 7.0 the options to activate BW Statistics is available in DWB (RSA1) ---> Tools ---> Settings for BI Statistics
(or) you can run the transaction RSDDSTAT to do the same
The BI admincockpit is process of one of the function known as Administration of the the DWWB.
We can also access this through the tcode ZPORTAL which is a single signon which will be having diff iviews as UWL,Webanalyser,BEx portfolio,My portfolio,Info

What should I use? Vectors or...

I'm storing a large amount of Person objects, this is for a type of game I'm trying to create where it saves the players name, wins, losses, rank, etc in each Person object (this will all be in a text file also). I want these so that they can be sorted by any one of these statistics. I'm not sure how to go about this. Vectors were the first thing that came to my mind, but then I thought about LinkedLists, but I don't know much about them yet, I just know it's an option. My brother told me use LinkedLists, but that's all he would tell me. What should I use for this kind of task? All suggestions are welcome, I need a little help with this design. One more thing about this, players will be added and removed also. I really need some insight, thanks.
This is a side question, if someone could answer it, that would be nice, otherwise it's ok. How does a LinkedList differ from a Vector? Can't everything a LinkedList do, a Vector can do also with the same amount of ease? All I know that LinkedLists point to the next and previous nodes or something like that, not really sure what its advantage is. Thank you.

An array memory for holding each of the objects is allocated when you create it, hence you have to define the number of object you want when you create it.
+--+--+--+--+--+--+
|I0|I1|I2|I3|I4|I5| < Indexs
+--+--+--+--+--+--+
|V0|V1|V2|V3|V4|V5| < Values
+--+--+--+--+--+--+Pro: you can access the data quickly, as you have a direct refrence to each value, via it's index.
Con: Fixed size
Con: Waisted space
A Vector is a growable array.
It does this by creating a fixed sized array, then waiting until it's full, then creating a bigger one and then copying all the data from the smaller, old array to the new, bigger array. This means that every now and again you suffer a performce hit as your array grows.
Pro: you can access the data quickly, as you have a direct refrence to each value, via it's index.
Pro: Not a fixed size
Con: Will slow down when it grows.
Con: Waisted space
A Linked List does not have this problem each element holds the refrence to the next, unlike an array where the "system" holds a refrence to each element. This reduces its memory footprint, however its slower to search through as you have to loop through all the objects.
+----+----+
|DATA|LINK|
+----+--|-+
        |     +----+----+
        +--> |DATA|LINK|
              +----+----+Pro: Growable
Pro: Size
Con: Slow to search
There are things you can do to speed up a linked list (double linked lists & improve the order in which they are added) but it's still slow.
I'll leave choosing the data structure to you.

What is the use of ST05 ? and how to use " ST05 "

can anybody tell me what is the use of " ST05 "
and how can we handle it.

SQL Trace
SQL trace(ST05) provides the developer with the ability to analyse database select statements. Simply execute ST05
to turn on SQL trace, then execute the statement/program you want to analyse. Now turn off SQL trace using ST05
and click on list trace to view the details.
You can also perform traces on other items such as authorisation objects.
Authorisation trace analysis 1. Open two sessions
2. Execute transaction ST01 in one of the sessions
3. Select the authorisation checkbox, note the other traces
you can perform (SQL, RFC, Table Buffer etc)
4. Click the 'Trace On' button
5. Within your other session execte the transaction/report
you want to trace or get the user in question to do it
6. Return to the session where you turned the trace on and
click on 'Trace Off' otherwise it will continue to record
all athorisation checks
7. Click on the 'Analysis' button
8. Enter appropriate data into selection screen such as
Username, type of trace records (i.e. Authorization check)
9. Click on the Execute button.
10. Report displaying trace results will now be displayed
http://www.sapdevelopment.co.uk/perform/perform_sqltrace.htm
Some useful transaction related to this are ..
ST01 SAP system trace
ST02 Buffer statistics.
ST03 Workload analysis.
ST04 Database performance analysis.
ST05 SQL trace .
ST06 Operating system monitor ...
From the recorded SQL trace you can deduce:
· Which SQL statements your application carries out
· Which values the system uses for specific database accesses and changes
· How the system translates ABAP OPEN SQL commands (such as
SELECT) into standard SQL commands
· Where your application positions COMMIT statements
· Where your application makes repeated database accesses
· What database accesses or changes occur in the update section of your
application
Look at the below links, you will get the idea

Check the following links:
http://www.sapbrainsonline.com/TOOLS/RUNTIMEanalysis/SAP_runtime_analysis.html
http://www.sapbrainsonline.com/TOOLS/SQLTRACE/SQL_TRACE.html
Use
The Performance Trace allows you to record database access, locking activities, and remote calls of reports and transactions in a trace file and to display the performance log as a list. It also provides extensive support for analyzing individual trace records.
SQL Trace: This allows you to monitor the database access of reports and transactions.
Enqueue Trace: This allows you to monitor the locking system.
RFC Trace: This provides information about Remote Function Calls between instances.
While the trace is switched on, the SQL Trace function records all database activity by a particular user or group of users. The R/3 System takes OPEN SQL statements and converts them in to embedded SQL statements that it passes to the database. It is the embedded SQL statements, their parameters, return codes, and the number of entries retrieved, inserted, or deleted that are recorded in the SQL Trace file. The log file also contains the runtime of the statement and the place in the application program from which it was called.
The SQL trace tells you:
The SQL statements executed by your program.
The values that the system uses for particular database access and changes.
How the system converts ABAP Open SQL statements (such as SELECT) into Standard SQL statements.
Where your application executes COMMITs.
Where your application repeats the same database access.
The database accesses and changes that occur in the update part of your application.

What is the use of this form?

Hi all,
What is the use of this form in include RV61B901?
How does this code send any information to the program calling it? Is Sy-subrc global so that main program will know the reuslts?
Code:
FORM KOBED_901.
DATA : l_anzpk LIKE likp-anzpk.
SELECT SINGLE anzpk FROM likp
                      INTO l_anzpk
                      WHERE vbeln = komkbv2-vbeln.
IF l_anzpk NE 0.
    sy-subrc = 4.
    exit.
ENDIF.
sy-subrc = 0.
ENDFORM.
Thanks,
Charles.

Hello,
This form sets the value of sy-subrc(which is global) based
on the value of l_anzpk.

What is the use of additon in up to 1 rows in SELECT statement

Hi All,
         What is the use of up to 1 rows in select statement.
for example
SELECT kostl
      FROM pa0001
      INTO y_lv_kostl UP TO 1 ROWS
      WHERE pernr EQ pernr
      AND endda GE sy-datum.
    ENDSELECT.
I'm unable to get in wat situations we hav to add up to 1 rows
please help me out...
Thanks,
santosh.

Hi,
Use "select up to 1 rows" only if you are sure that all the records returned will have the same value for the field(s) you are interested in. If not, you will be reading only the first record which matches the criteria, but may be the second or the third record has the value you are looking for.
The System test result showed that the variant Single * takes less time than Up to 1 rows as there is an additional level for COUNT STOP KEY for SELECT ENDSELECT UP TO 1 ROWS.
The 'SELECT .... UP TO 1 ROWS' statement is subtly different. The database selects all of the relevant records that are defined by the WHERE clause, applies any aggregate, ordering or grouping functions to them and then returns the first record of the result set.

What is the use of Alternative Calculation Type =2 and 4

Dear Friends
In pricing procedure in gross value, Net value for Item and Net value has Alternative calucation type is 2.
What is the use of it?
Without using it these value line are also fetching net value then what is the work of it. Please give me detail information with its effects in pricing condition tab page in sales document.
Thanking You
Arun

Arun biswal,
Correct Biswal. We have at varoius stages within Pricing procedure the "net value" which is calculated. Not only the alternative calculation type "2" is used if you notice carefully they are stored as subtotals at various levels.
For Ex Gross Value --> Subtotal =1 --> Calc type = 2
similarly for Net value for Item --> Subtotal =2 --> Calc type = 2
Net value 2 --> Subtotal =3 --> Calc type = 2
See, these are used to calculate the net value at various levels in pricing. The calculation Type has got a set of routines that will facilitate us in pricing. SAP has provided certain clauclated formulas or routines to facilitate us during calculation within pricing . Here the "2" is used for calculation without tax and store it as subtotal and display it or use it for further calculations.
We can use this "netvalue" amount for further calculations. It is used for clarity purpose when you issue a statement to customer. (like Confirmation order) at various levels like discount amt involved, Freight involved, Rebate amount invloved.....
Even without this Calc type or using sub total u can proceed....
Finally we have TOTAL --> Subtotal =A --> Calc type = 4
In the above line we have Calc type as 4, which means when you use TAX this calc type is used .
Routines are used to facilitate your process....

What is the use of Data packet dim with Virtual cube with services

Hi Friends,
Could anybody tell me what is the use of Packet dimension in Virtual cube with services , It cannot contain data persistently ,Just fetch at runtime,Then there is no Physical load happening,Then why it should be automatically created for this??
Message was edited by: Pradeep choudhari

Hi Maik,
Unit dimension will not be created automatically until and unless you have keyfigure referning units..
But my question is : Why should we have data pack dimension , which is useless in this case of Virtual cube with services.It should not be created automatically!! What do you say??

What's the use of description of a bookmark? Find Bookmark in Bookmark-Tree? FavIcons on second synced devide?

1. I'm a little bit confused about the useage of descriptions of a bookmark.
For what can I use it after I filled something in?
Is the intention to open the booksmark property to see what I have filled in a long time ago?
Maybe I could be useful to add this to the Bookmarks tooltip?!
2. I have many Bookmarks in many Subfolders.
But sometimes I don't find a Bookmark. So I try to find it over the awesome-Bar and I find it.
Is it possible to see in the awesome-bar/SearchFunktionInBookmarkLibrary where I have the Bookmark in my Bookmarktree?
3. I have synced my Bookmarks to a second PC. Is it possible to load all favicons an this device?

# The description field provides additional information about a bookmark. From what I can see, it's only visible in the Library. The field is automatically filled in when you bookmark a page that contains a description, e.g.
#* http://www.w3schools.com
# The following add-ons make locating bookmarks easier in the Library and the sidebar.
#* https://addons.mozilla.org/firefox/addon/show-parent-folder/
#* https://addons.mozilla.org/firefox/addon/go-parent-folder/
#* https://addons.mozilla.org/firefox/addon/sidebar-bookmarks-search-plus/
# You can try the Favicon Reloader add-on to reload missing site icons.

What is the use of Withholding tax identification number field?

Hello SAP Experts,
I posted this question earlier but had to close because of no replies from anybody. Posting it again to see if I am lucky to get some answer this time.
Can someone tell what is the use of field Withholding Tax Identification Number? Does it help with the reporting? Where does it get populated on the report if given at vendor or master record or within the withholding tax customization for company code? What is the difference between creating it in the customization for withholding tax information for company code and vendor/customer master record?
As per SAP: Withholding tax identification number
This is a number issued by the tax authorities per withholding tax type.
This number must be specified in Customizing either:
(a) As part of the withholding tax information defined for the company code, or
(b) As part of the withholding tax information defined in the customer or vendor master record.

Hi Pete,
The only thing that I could check is the content used in US:
See content of this field for US:
LFA1-STCD1 Social security number
LFA1-STCD2 Employer identification number
LFBW-WT_WTSTCD Withholding tax identification number for WT Type
In order to populate it, please kindly check the following:
The reason why you cannot fill in the field WT_WTSTCD in transaction
Fk02 however you can do it in XK02 (Change vendor centrally) can be due
to wrong customizing of the field status group.
Kindly check the following:
SPRO->
Finantial accounting -> Accounts receivable and accounts payable ->
Define screen layout per activity (vendors) -> Change Vendor(Accounting)
Company code data -> W/holding tax data, w/h tax 2 ->
FIELD Withholding tax code,w/h tax 2 will be probably just available to
display. Please, change it to optional entry.
I hope I could be of assistance.
Kind Regards,

What is the use of HTTPS 8181 port

Hi,
I am wondering what is the use of the port 8181 on the EE5 application server.
the second question. Why the application server open so many port on the same local machine. I agree that for security raison it is a good idea. But does application serveur use tcp connection to communicate between the server thread ?
So it is possible to add a thread in the serveur application to process some internal work. And of course it is possible to include this new thread in the communication process of the server ?
Can we have the map of all the tcp trhead use by the server application.
Regards
Herve Terrolle.

Your app has to run as root to listen on ports up to 1024,
also, some other app (apache?) may already be listening on port 443.
AFAICT port 8181 is just arbitrarily chosen, it might as well have been port 4430, or any other free port above 1024.

Dont give me this answer.
ORA-16196: database has been previously opened and closed
Cause: The instance has already opened and closed the database, which is allowed only once in its lifetime.
Action: Shut down the instance.

If you read the documentation you will see that there is no ALTER DATABASE CLOSE command.
This is an undocumented Oracle command, which we are not supposed to use. Consequently we are not allowed to complain about the way that it works. Instead we're supposed to use SHUTDOWN IMMEDIATE.
