Please explain the MODULE in ABAP programming

Hello SAP gurus,
Kindly explain MODULES in programming...
Thank you very much!

hi there....
before i go ahead, i take this as u know report programming. so chk this link to find differences between the two
http://www.geekinterview.com/question_details/18029
mostly, dialog programming helps the user to forget about the layout as it does this automatically for us. we need to concentrate on the logic. it sometimes gives a feel of visual basics. moreover, it can write on the database other than fetching data from it as in report programming.
do reward if helpful or get back with further queries.

The performance of ABAP programs

Hey Experts , how can one analyze the performance of ABAP programs apart from using the generic tools such as Trace etc.

Hi Chakradhar,
Overview & Introduction
The runtime analysis tool allows you to examine the performance of any ABAP programs, such as reports, subroutines, function modules or classes, that you create in the ABAP workbench. It saves its results in performance data files, which you can display as lists. You can use these results to identify runtime-intensive statements, to combine table accesses, and show the hierarchy of program calls.
Normally you use the runtime analysis tool to measure the runtime of complex program segments or complete transactions (if you want to measure the runtime of smaller program segments or individual ABAP statements you can use the ABAP statement GET RUN TIME FIELD ).
However, we use only simple
The Programs to be Analyzed
Let's assume I am a very newbie in ABAP and I have written a tiny little program which is doing the following:
reading data from a database table
storing that data in an internal table
display that data on a list (at the start of the program you have to specify certain key values; only matching data should be displayed later on).
So here it comes (and it seems to work as designed ...)
REPORT y_wlog_atra_1.
PARAMETERS: p_carrid TYPE sbook-carrid DEFAULT 'LH',
            p_connid TYPE sbook-connid DEFAULT '0400'.
DATA: wa_sbook TYPE sbook,
      itab_sbook TYPE STANDARD TABLE OF sbook.
*SELECT * FROM sbook INTO wa_sbook.*
CHECK: wa_sbook-carrid = 'LH' AND
         wa_sbook-connid = '0400'.
APPEND wa_sbook TO itab_sbook.
ENDSELECT.
LOOP AT itab_sbook INTO wa_sbook.
WRITE: /,
         wa_sbook-carrid,
         wa_sbook-connid,
         wa_sbook-fldate,
         wa_sbook-bookid,
         wa_sbook-customid,
         wa_sbook-custtype.
ENDLOOP.
A nice colleague has thrown a glance at my source code. He has given the hint to use a WHERE clause with the SELECT statement instead of the CHECK statement for reasons of better performance.
So I have written another program:
REPORT y_wlog_atra_2.
*SELECT * FROM sbook INTO wa_sbook*
WHERE carrid = 'LH' AND
        connid = '0400'.
APPEND wa_sbook TO itab_sbook.
ENDSELECT.
I am curious about the performance now. Let's compare the 2 variants with the ABAP Runtime Analysis tool.
ABAP Runtime Analysis: Tool & Procedure
To start it, choose Test --> Runtime Analysis in the SAP Menu, or use transaction SE30 .
The runtime analysis procedure consists of two parts:
Recording performance data (upper part of the screen)
Analyzing the performance data (lower part of the screen; this part only appears if there are performance data files in place)
The procedure for the first part (Recording performance data):
We go to the initial screen of the runtime analysis (transaction code SE30 ) and specify the name of the first program (Y_WLOG_ATRA_1) in the relevant input field. After that we press the button Execute .
The selection screen of the program Y_WLOG_ATRA_1 (including the 2 input fields) is displayed. At the bottom of the screen we are informed that the measurement has been started. We continue by clicking the Execute button.
Later on we will see that a file (containing performance data) has been created in parallel.
Now we repeat that procedure for our second program (Y_WLOG_ATRA_2).
The second step is the analysis of the generated performance data.
To do that we have to go to the initial screen of the Runtime Analysis tool again. On the bottom part of the screen you can specify those performance data files you want to analyze.
You can see some information related to the last measurement run (in our case that was program (Y_WLOG_ATRA_2). By pressing the button Other File we are able to select those performance data files we like to analyze.
I want to see all the files I have created (user BCUSER).
I get the relevant list with 2 lines (related to the performance data files of the programs Y_WLOG_ATRA_1 and Y_WLOG_ATRA_2).
Based on that list you can display the distinct performance data per line. You have to click in the column Object Type of the relevant line.
As a start the tool displays the evaluation overview (showing the cumulated execution times for the ABAP, database and system-level).
Here comes the evaluation overview for program Y_WLOG_ATRA_1
We can do the same for the other program Y_WLOG_ATRA_2
By comparing the perfomance data of the 2 programs we clearly see that I have done well with listening to the advice of my colleague. The performance of the second program is dramatically better.
In the next step you can forward to a more detailed display of the performance data (Hitlists). That listing shows the different granular execution steps ( according to your filter adjustments ). Here you can easily identify the most time-consuming progam units.
And it will also be a good idea to glance at the Tips & Tricks corner. You will find many valuable suggestions about good performance definitely.

Updating liveCache Data using Function Module or ABAP program.

Is it possible to update APO Live Cache using Function Module or ABAP Program.
Will the aggregation/disaggreagation remain the same if data is modified using Function Module or ABAP Program.
Regards,
Vikas

ello Vikas,

& read about 'SAP liveCache'.
As you know objects stored in liveCache in the class containers can be accessed
and manipulated only via LCA routines which are methods of LCA objects.
The registration of the LCA routines is done automatically when
the liveCache is started by the LC10, check the lcinit.log file.
The shared procedures in the LiveCache are written in C++ and shipped
to the customers as binary shared libraries(LCA-Routines) < LCA build >
together with the LiveCache. The original C++ source code of the
libraries is not generally available to the customers.
The LCA routines could be called via "/SAPAPO/OM*" ABAP functions.
-> For SAP liveCache documentation in English:
http://help.sap.com/saphelp_nw04/helpdata/en/f2/0271f49770f0498d32844fc0283645/frameset.htm
< -> Database Administration in CCMS: SAP liveCache -> liveCache Assistant ->
liveCache: Monitoring -> Problem Analysis-> DB Procedures >
In transaction LC10 for the LCA connection choose liveCache:Monitoring
then go to Problem Analysis -> DB Procedures=>
The system displays an overview of all database procedures loaded into
liveCache, their input and output parameters, and other details.
-> Tr. /n/SAPAPO/OM16 ( in further releases /n/sapapo/om19 ) is provided by
SAP to get information about data stored in the LiveCache. If you would
like to get your own views, you should write a special report in ABAP using
"/SAPAPO/OM"-development class functionality.
-> There are standard function modules in ABAP available to extract/change data from/in liveCache.

To upload the file , you can try a standard program "RSEPSFTP" .
while you execute the program , a selection screen appears in which the inputs should be give as
RFC destination - The target server name
FTP command- PUT
local file - your file name
local directory - path of your local file
remote file - your target file name
remote directory - where it has to be stored
Hope this is useful for you

Please explain, the job of the "ASSIGN COMPONENT ".

Please read this popular example appended below. I am newbie to ABAP.
At the end of the execution the code is printing 33. Don't get it.
Please explain, the job of the "ASSIGN COMPONENT ". How or why it is printing value 33. What is the meaning of the statement, "ASSIGN COMPONENT <F2> OF STRUCTURE <F1> TO <F3>." ?
DATA: BEGIN OF LINE,
COL1 TYPE I VALUE '11',
COL2 TYPE I VALUE '22',
COL3 TYPE I VALUE '33',
END OF LINE.
DATA COMP(5) VALUE 'COL3'.
FIELD-SYMBOLS: <F1>, <F2>, <F3>.
ASSIGN LINE TO <F1>.
ASSIGN COMP TO <F2>.
DO 3 TIMES.
ASSIGN COMPONENT SY-INDEX OF STRUCTURE <F1> TO <F3>.
WRITE <F3>.
ENDDO.
ASSIGN COMPONENT <F2> OF STRUCTURE <F1> TO <F3>.
WRITE / <F3>.
11 22 33
33

DATA: BEGIN OF LINE,
COL1 TYPE I VALUE '11',
COL2 TYPE I VALUE '22',
COL3 TYPE I VALUE '33',
END OF LINE.
DATA COMP(5) VALUE 'COL3'.
FIELD-SYMBOLS: <F1>, <F2>, <F3>.
ASSIGN LINE TO <F1>.
ASSIGN COMP TO <F2>. "here you are assigning the column name which is COL3 to <f2>.
DO 3 TIMES.
ASSIGN COMPONENT SY-INDEX OF STRUCTURE <F1> TO <F3>.
WRITE <F3>.
ENDDO.
ASSIGN COMPONENT <F2> OF STRUCTURE <F1> TO <F3>.
ASSIGN 'COL3' of structure <f1> to <f3>. "it is equal to above statement.
WRITE / <F3>.
11 22 33
33
ASSIGN COMPONENT <F2> OF STRUCTURE <F1> TO <F3>. means
assigining COL3 value of the structure <f1> to <f3>, so value is 33 , it will be assigned to <f3> .it prints 33.

Function Modules and ABAP programs Where-Used

Hi,
Can anyone teach me on how to check where a function module or ABAP programs have been used? When I click the where-used button, there's nothing found but I know the FM/ABAP programs have been used somewhere.
Thanks.

Hi,
This is very basic question, you simply need to go to transaction SE37 for FM and click on the where used list, in the next popup you will have to make proper selections, e.g. ABAP reports, FM's etc. then it will give you the list of objects where the current object is getting used.
I am not sure whether we will have any where used list for SE38 programs, just check it out.

Durgesh.

Can any please explain the integration business process between PS and CS

Dear Guru's
Can any please explain the integration business process between Project systems (PS) and customer service (CS).
Business Process: We do machinery Erection or commissioning, later we do provide service warranty for one year.
How we map this Business scenario in sap.
Regards,
Bhanu

basic steps for such a process would be
1) Use PS functionality for your machinery erection or commisioning work. Once the physical work is completed then close porject
2) Use CS functionality for warranty and service - set up the work as a functional location on customer site (PM/CS functionality)
3) Use service order to manage any service calls on the object which could require billing via SD module - bill value may be zero if under warranty

Problem with the active version of the transfer rule ABAP program with sour

Hi,
I have a problem with the active version of the transfer rule ABAP program with source system EXCEL.
The system does not react to changes done in the transfer rule coding. For FISCPER I have hardcoded the result 'BABABA' and still the results delivered are those from the CSV.
Resetting the system buffers does not help. The problem is systematic in combination with source system EXCEL (i.e. not only 1 InfoSource). Checking the active program Extras->Display Program shows the coding (result='BABABA') being there, but
as stated, the system does not produce the result BABABA, but instead the result of the CSV.
It seems as if the original version from the very first activation of the transfer rule program remains somewhere and continues to be used. Does anybody know how to flush it out and get the system to actually use the coding appearing as the active program.
I have posted an OSS note, but SAP takes it time to answer and I am under time pressure so I figured that maybe one of you know who to solve it before SAP does.
Greetings and thanks,
Martin

Hi martin,
just try to go out the RSA1 and then return to your infopac. ...

Only the suthor of ABAP programs can see and edit his/her code

Hi:
We've created developer accounts with the following authorization profiles: A_ABAP_ALL, S_A.DEVLOPER, AND S_A.USER.
The account holder can access the system, create ABAP programs, and successfully run them. However, there is a problem: a user can see and edit the programs of others.
Can we set up the account in such a way that only the author of the program can see and edit it? If YES, what should we do?
Thanks a lot for the help,
Thuan Nguyen

Hi Gus:
Thanks a lot for the help. For creating profiles, I read into 2 different books to get the steps that show how to do it. however, both of them only discuss the general things and do not get to the steps of how to do it.
Do you know what I need to do to create profiles or where I can get some documentation with details of how to do it?
Thanks a lot

Please explain the magic! (Question)

The ActionScript snippet below is from the BlaseDS chat sample app. Can someone please explain the magic that declares the chatMessage property of AsyncMessage.body (IMessage.body?) object? It's not in the docs anywhere so I'm guessing it is not built into AsyncMessage. And it's not defined in any of the sample app source files.
Coming from a strongly-typed development world, seeing a property that apparently has no declaration and is not explicitly instantiated does not pass the sniff-test.
Thanks.
<mx:Script>
<![CDATA[
   import mx.messaging.messages.AsyncMessage;
   import mx.messaging.messages.IMessage;
   private function send():void
    var message:IMessage = new AsyncMessage();
    message.body.chatMessage = msg.text;
    producer.send(message);
    msg.text = "";
   private function messageHandler(message:IMessage):void
    log.text += message.body.chatMessage + "\n";
]]>

Hold your nose, because that is the dynamic "feature" of Actionscript. Pretty much every class derives from Object (http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/Object.html) which is a dictionary of key-value property pairs. The {"chatMessage", msg.text as Object} pair is created upon assignment.
I am fairly new to Flex/AS, and while not having to declare types is convenient for quick and dirty coding, I try to avoid it in production code...I have been bitten by refactoring a class and not catching all the places where it was referenced dynamically. I'm sure there are comprehensive pro and con arguments out there.

2 GB Limit – Please explain the concept

I have more than 35000 photos already uploaded into Revel.
In order to continue to remain a Free member, shall I have to delete all my photos and keep only within 2 GB limit?
Please explain the new concept... Thanks!

You may continue to use revel free of charge with the new model change, however, if you have stored more than 2 GB of files, then you will be unable to upload any additional photos/videos until you delete some files to take you below the limit or subscribe to get unlimited uploads.

TS1503 In the iPhone, please explain the requirements in settings for Apple id, iPhone and iCloud

In the iPhone, please explain the requirements in settings for Apple id, iPhone and iCloud

You can use 1 unified Apple ID for iTunes so you don't have to repurchase apps. That part is fine.
For iCLoud/iMessage/Facetime you should each have a unique ID so the 2 phones will be separate and you won't accidentally erase each other's content and overwrite settings, nor will you get the others messaages by mistake.
