Could you please explain about the chain and end chain and module

hi experts
could you please explain about the chain and end chain and module keywords?

Hi Naresh,
Conditions for Multiple Screen Fields
To ensure that one or more PAI modules are only called when several screen fields meet a particular condition, you must combine the calls in the flow logic to form a processing chain. You define processing chains as follows:
CHAIN.
ENDCHAIN.
All flow logic statements between CHAIN and ENDCHAIN belong to a processing chain. The fields in the various FIELD statements are combined, and can be used in shared conditions.
CHAIN.
FIELD: <f1>, <f 2>,...
MODULE <mod1> ON CHAIN-INPUT|CHAIN-REQUEST.
FIELD: <g1>, <g 2>,...
MODULE <mod2> ON CHAIN-INPUT|CHAIN-REQUEST.
ENDCHAIN.
The additions ON CHAIN-INPUT and ON CHAIN-REQUEST work like the additions ON INPUT and ON REQUEST that you use for individual fields. The exception is that the module is called whenever at least one of the fields listed in a preceding FIELD statement within the chain meets the condition. So <mod1> is called when one of the fields <fi> meets the condition. <mod2> is called when one of the fields <f i> or <g i> meets the condition.
Within a processing chain, you can combine individual FIELD statements with a MODULE statement to set a condition for a single field within the chain:
CHAIN.
FIELD: <f1>, <f 2>,...
FIELD <f> MODULE <mod1> ON INPUT|REQUEST|*-INPUT
|CHAIN-INPUT|CHAIN-REQUEST.
MODULE <mod2> ON CHAIN-INPUT|CHAIN-REQUEST.
ENDCHAIN.
The module <mod1> is called when screen field <f> meets the specified condition for individual fields. <mod2> is called when one of the fields <fi> or <f> meets the condition. If you use the addition ON CHAIN-INPUT or ON CHAIN-REQUEST with FIELD <f>, the condition also applies to the entire chain and module <mod1> and <mod2> are both called.
In cases where you apply conditions to various combinations of screen fields, it is worth setting up a separate processing chain for each combination and calling different modules from within it.
The functions of the FIELD statement for controlling data transport also apply when you use processing chains. Within a processing chain, screen fields are not transported until the FIELD statement. Processing chains also have another function for the FIELDS statements that they contain. This is described in the section on validity checks.
Ex:
PROCESS AFTER INPUT.
MODULE CANCEL AT EXIT-COMMAND.
CHAIN.
FIELD: INPUT1, INPUT2.
MODULE MODULE_1 ON CHAIN-INPUT.
FIELD INPUT3 MODULE MODULE_* ON *-INPUT.
MODULE MODULE_2 ON CHAIN-REQUEST.
ENDCHAIN.
FIELD INPUT1 MODULE C1 AT CURSOR-SELECTION.
CHAIN.
FIELD: INPUT2, INPUT3.
MODULE C2 AT CURSOR-SELECTION.
ENDCHAIN.
MODULE CURSOR AT CURSOR-SELECTION.

Could you please send me the material Opps concepts Classes and Methods

Hi Experts,
I am working on Opps concepts.I am new to this concept.
Could you please send me the detailed presentation on Abap oops.
Thanks inadvance,
Regards,
Rekha.

Hi this will help u.
OOPs ABAP uses Classes and Interfaces which uses Methods and events.
If you have Java skills it is advantage for you.
There are Local classes as well as Global Classes.
Local classes we can work in SE38 straight away.
But mostly it is better to use the Global classes.
Global Classes or Interfaces are to be created in SE24.
SAP already given some predefined classes and Interfaces.
This OOPS concepts very useful for writing BADI's also.
So first create a class in SE 24.
Define attributes, Methods for that class.
Define parameters for that Method.
You can define event handlers also to handle the messages.
After creation in each method write the code.
Methods are similar to ABAP PERFORM -FORM statements.
After the creation of CLass and methods come to SE38 and create the program.
In the program create a object type ref to that class and with the help of that Object call the methods of that Class and display the data.
Example:
REPORT sapmz_hf_alv_grid .
Type pool for icons - used in the toolbar
TYPE-POOLS: icon.

Can you please explain about the vehicle management system?

Hi ,
i want to know about the module (vehicle management system) .please explain any one in details .
Regards
Venkata .

Hi Venkata,
The Vehicle Management system (VMS) is part of SAP IS - Auto. Generally it is said that it is used by importers, however I would rather put it like this – It can be used for an importer or a distributor’s business functions. So if an OEM is also performing a distributor’s business, he can also use VMS and get benefited out of it.
The VMS facilitates to see a Vehicle like a Vehicle in the system.
Following are the few high level features -
It allows to capture all the attributes of a particular vehicle as an unique object in the system
All the transaction on a vehicle (sales, purchase etc.) can be carried out keeping vehicle as a central object, provides ease of operation to users. All business and technical data of the vehicle is available here.
Strong configuration based vehicle search and vehicle history (transactions) helps in tracking the vehicle easily for any purpose in the distribution chain of OEMà Distributorà Dealerà End Customer.
This is in brief about VMS.

Could you please explain when we connect R/3 system to BW

Hi,
could you please explain when we connect R/3 system to BW
1. Procedure
2. SAP BW need to do anything
3. Effort required by SAP BW
Regards,
kranthi

Hello Kranthi,
When we need to make a conncetion between R/3 & BW , First logon to R/3 system , Go to T/code - SM59 .
There u find connections . Select on ABAP and click on New
Then Provide the description
Go to technical settings tab :
Provide load balancing : No
if you know the server name : give it in the target host name
or give the IP Address ;
Then after that go to logon & Security Tab :
provide the RFC user ID , Client & Password .
And now check the connection by clicking on the connection test
If it shows some 2mins ,like that then it is ok ...
Otherwise then it is a problem ...
repeat the same thing by giving the target as R/3 here .
now go the RSA1 , select the source systems , create source systems
Select BW source systems
give the target system details , such as system no . System ID ,server name ..
And also background user id & password for both the target systemm & source system .
Now Select the created source system , context menu & Check the connection .
This job is performed with the help of basis people , not only by BW team .
This is maintaince is done for every system ( Dev , Qaulity & production seperately )
Thanks

Could you please explain how to work with Outlier Correction

could you please explain how to work with Outlier Correction

Hi sr,
Actually an outlier correction is an historical value that lies the tolerance lane.
the apo sys calculate this tolerance lane on the basis of the sigma factor.
It then correct any historical value that lies outside the upper or lower band of this tolerance lane.
So, that it corresponds to the calculated ex- post value for that point in time.
this option is available in Master forecast profile /sapapo/mc96b in Univariate profile( control parameters) tab.
If you have set the outlier correction indicator, then the sys first calculate an ex-post forecast with the selected forecasting techniques.
In the next step, the sys calculates a tolerance threshold T.
where T is calculated as T = sigma * MAD (Mean Absolute Deviation)
Here the Sigma factor defines the width of the tolerance rangefor automatic outlier correction.
it defines the permissible number of standard deviations.
A small sigma factor means a low tolerance, and a large number of outliers that are detected and corrected.
The default Sigma factor is 1.25.
If you set the Sigma factor, SAP recommends that you set it betw 0.6 and 2.
I hope this is helpful for you.
Regards,
Pullaiah

Hi Do we have tables for SAP BPC EPM Comments ? if we have what are they could you please explain some one.

Hi Do we have tables for SAP BPC EPM Comments ? if we have what are they could you please explain some one.

Hi Narahari,
Yes, we have tables for SAP BPC EPM comments and it is stored in backend BW.
Please follow the below steps to see it -
1. Go to RSA1 and find the infoprovider name for the application/cube that contains the comments For example, the infoprovider name is /CPMB/VZIKG4O
2. Then Go to SE16 and enter the comment table name. The comment tables are generated tables. You can determine there name by using the following rules:
a. The table name always starts with '/1CPMB/'
b. The rest of the name is derived from the infoprovider name - it is the first two characters after the second '/' + the fourth, fifth and sixth characters + CMT (for comments) or CMTA (for archived comments). In my case the comments table name would be "/1CPMB/VZKG4CMT" and the archived comments table would be "/1CPMB/VZKG4CMTA".
3. Hit 'F7' or click the table contents button.
4. Enter the criteria for the comments you wish to export.
Hope this helps.

Hi there, i have Q i have excel file it need to be block with password. Could you please explain how i make password protect to Excel document

Hi there,
i have Q i have excel file it need to be block with password. Could you please explain how i make password protect to Excel document
Thanks

On the File menu, click Save As.
On the Tools menu, click General Options.
Do either or both of the following:
If you want users to enter a password before they can view the workbook, type a password in the Password to open box, and then click OK.
If you want users to enter a password before they can save changes to the workbook, type a password in the Password to modify box.
NOTE   Unlike passwords you specify in the Password to open box, passwords you specify in the Password to modify box are not encrypted. These passwords are only meant to give specific users permission to modify workbook data. For optimal password security, it's best to assign both passwords. An encrypted password to access the workbook, and one to provide specific users with permission to modify its content. IMPORTANT   Use strong passwords that combine uppercase and lowercase letters, numbers, and symbols. Weak passwords don't mix these elements. Strong password: Y6dh!et5. Weak password: House27. Use a strong password that you can remember so that you don't have to write it down.
If you want to use a different encryption type, click Advanced, click the type you want in the Choose an encryption type list, and then click OK.
If needed, specify the number of characters you want in the Choose a key length box.
NOTE   Document property encryption is enabled by default for most encryption types and providers. It prevents unauthorized users from viewing summary and custom file properties (such as the author or any custom file information) in theProperties dialog box. When users right-click the password-protected file, and then click Properties, information won't be available on the Summary tab and Customtab. Authorized users, however, can open the file and view all file properties (Filemenu, Properties command). To disable document property encryption, clear theEncrypt document properties check box.
Click OK.
When prompted, retype your passwords to confirm them.
Click Save.
If prompted, click Yes to replace the existing workbook.
NOTE   You can also secure a workbook with a password on the Security tab of the Options dialog box (Tools menu, Options command).

Could you Please Send me the Step by Step guide for the BADI

Hi ABAPers,
Could you Please Send me the Step by Step guide for the BADI.It is very Urgent
Thanks & Regards,
Ashok.

Each BAdI has a definition and more than one implementation. The definition means the methods(in class concept) that are used for performing various functions. The BAdI definition can be viewed in SE18 transaction(for standard ones) and user-defined BAdIs can be created in the same transaction as well.
When you create a BAdI definition, an class interface will be automatically created and you can define your methods in the interface. The implementation of the methods can be done in SE19 transaction .

suppose your working for XK01 then for that the BADI being VENDOR_ADD_DATA then this implemetation procedure.
Steps:
1. Execute Business Add-In(BADI) transaction SE18
2. Enter BADI name i.e. VENDOR_ADD_DATAand press the display
button
3. Select menu option Implementation->Create
4. Give implementation a name such as Z_VENDOR_ADD_DATA
5. You can now make any changes you require to the BADI within this
implementation, for example choose the Interface tab
6. Double click on the method you want to change, you can now enter
any code you require.
7. Please note to find out what import and export parameters a
method has got return the original BADI definition
(i.e. VENDOR_ADD_DATA) and double click on the method name
for example within VENDOR_ADD_DATA contract is a method
8. When changes have been made activate the implementation
BADI(Business Add-In) is the object oriented method of user exits...
Each BAdI has a definition and more than one implementation. The definition means the methods(in class concept) that are used for performing various functions. The BAdI definition can be viewed in SE18 transaction(for standard ones) and user-defined BAdIs can be created in the same transaction as well.
When you create a BAdI definition, an class interface will be automatically created and you can define your methods in the interface. The implementation of the methods can be done in SE19 transaction

New to Badi
Follow the below steps to find out what all BADI's are called when you press any button in any transaction.
1) Goto se24 (Display class cl_exithandler)
2) Double click on the method GET_INSTANCE.
3) Put a break point at Line no.25 (CASE sy-subrc).
Now
4) Execute SAP standard transaction
5) Press the required button for which you need to write an exit logic, the execution will stop at the break point.
6) Check the values of variable 'exit_name', it will give you the BADI name called at that time.
7) This way you will find all the BADIs called on click of any button in any transaction.
Business Add-Ins
Business Add-Ins are a new SAP enhancement technique based on ABAP Objects. They can be inserted into the SAP System to accommodate user requirements too specific to be included in the standard delivery. Since specific industries often require special functions, SAP allows you to predefine these points in your software.
As with customer exits (SMOD/CMOD [Page 40]), two different views are available:
In the definition view, an application programmer predefines exit points in a source that allow specific industry sectors, partners, and customers to attach additional software to standard SAP source code without having to modify the original object.
In the implementation view, the users of Business Add-Ins can customize the logic they need or use a standard logic if one is available.
In contrast to customer exits, Business Add-Ins no longer assume a two-system infrastructure (SAP and customers), but instead allow for multiple levels of software development (by SAP, partners, and customers, and as country versions, industry solutions, and the like). Definitions and implementations of Business Add-Ins can be created at each level within such a system infrastructure.
SAP guarantees the upward compatibility of all Business Add-In interfaces. Release upgrades do not affect enhancement calls from within the standard software nor do they affect the validity of call interfaces. You do not have to register Business Add-Ins in SSCR.
The Business Add-In enhancement technique differentiates between enhancements that can only be implemented once and enhancements that can be used actively by any number of customers at the same time.
In addition, Business Add-Ins can be defined according to filter values. This allows you to control add-in implementation and make it dependent on specific criteria (on a specific Country value, for example). All ABAP sources, screens, GUIs, and table interfaces created using this enhancement technique are defined in a manner that allows customers to include their own enhancements in the standard.
A single Business Add-In contains all of the interfaces necessary to implement a specific task. In Release 4.6A, program and menu enhancements can be made with Business Add-Ins. The actual program code is enhanced using ABAP Objects. In order to better understand the programming techniques behind the Business Add-In enhancement concept, SAP recommends reading the section on ABAP Objects

u can find BADI's in different ways...
1>First go to any transaction->iN THE menu bar SYSTEM->STATUS->Get the program name ->double click->u will go to the program attached to the tcode.Now search term will be CALL CL_EXITHANDLER.Now u will get list of BADI'S available..
2>Goto SE24->Give class name as CL_EXITHANDLER->Display->double click on get_instance mathod->Now u will go inside the method->Now put break point on the cl_exithandler.Now go to any transaction code and pass dat..U will see that it will be stopped on the break point which u set on the cl_exithandler...In the exit name u can find list of badi's attached to the tcode..
There are multiple ways of searching for BADI.
Finding BADI Using CL_EXITHANDLER=>GET_INSTANCE
Finding BADI Using SQL Trace (TCODE-ST05).
Finding BADI Using Repository Information System (TCODE- SE84).
1. Go to the Transaction, for which we want to find the BADI, take the example of Transaction VD02. Click on System->Status. Double click on the program name. Once inside the program search for CL_EXITHANDLER=>GET_INSTANCE.
Make sure the radio button In main program is checked. A list of all the programs with call to the BADIs will be listed.
The export parameter EXIT_NAME for the method GET_INSTANCE of class CL_EXITHANDLER will have the user exit assigned to it. The changing parameter INSTANCE will have the interface assigned to it. Double click on the method to enter the source code.Definition of Instance would give you the Interface name.
2. Start transaction ST05 (Performance Analysis).
Set flag field "Buffer trace"
Remark: We need to trace also the buffer calls, because BADI database tables are buffered. (Especially view V_EXT_IMP and V_EXT_ACT)
Push the button "Activate Trace". Start transaction VA02 in a new GUI session. Go back to the Performance trace session.
Push the button "Deactivate Trace".
Push the button "Display Trace".
The popup screen "Set Restrictions for Displaying Trace" appears.
Now, filter the trace on Objects:
V_EXT_IMP
V_EXT_ACT
Push button "Multiple selections" button behind field Objects
Fill: V_EXT_IMP and V_EXT_ACT
All the interface class names of view V_EXT_IMP start with IF_EX_. This is the standard SAP prefix for BADI class interfaces. The BADI name is after the IF_EX_.
So the BADI name of IF_EX_CUSTOMER_ADD_DATA is CUSTOMER_ADD_DATA
3. Go to Maintain Transaction (TCODE- SE93).
Enter the Transaction VD02 for which you want to find BADI.
Click on the Display push buttons.
Get the Package Name. (Package VS in this case)
Go to TCode: SE84->Enhancements->Business Add-inns->Definition
Enter the Package Name and Execute.
Here you get a list of all the Enhancement BADIs for the given package MB.
The simplese way for finding BADI is
1. chooes Tcode Program & package for that Tcode.
2. Go to Tcode se18
3. Press F4
4. search by package or by program.

The Director role is optional in Lync Server 2013 - could anyone please explain why the director server has lost its importance??

Could anyone please explain why the director has been removed from spotlight as it had much importance in LYNC 2010 and now being an optional role in LYNC server 2013.[any call flows regarding director servers would be much useful]

Hi SJ Praveen,
A Director is a server running Lync Server 2013 that authenticates user requests, but does not home any user accounts. Lync 2013 Front End servers have the same registrar service and functionality
as the Director.
The Director isn't providing any special functionality. If the Director goes down, all pools would become inaccessible when the clients queried DNS for the SRV record until an administrator
makes a manual internal DNS change that points users to a Front End pool to handle the sign-in request from Lync clients. Microsoft has made the Director functionality relevant for organizations that have specific security requirements, such as allowing all
external users to register to a specific internal server instead of the Front End servers. This server role is merely optional and not needed for most Lync Server 2013 deployments.
Best regards,
Eric

Could you please tell me the arithmetic of ORA_HASH? Thanks.

Hello,
I need to use java code to implement the function of ORA_HASH(expr, max_bucket, seed_value).
I saw the ORA_HASH(expr, max_bucket, seed_value)'s description from http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b10759/functions097.htm.
But I still don't know the detailed arithmetic of ORA_HASH(expr, max_bucket, seed_value).
So could you please tell me the detailed arithmetic of ORA_HASH(expr, max_bucket, seed_value)?
Thanks.

Not sure Oracle will actually divulge the internal workings of their functions to you.
However, they are standard algorithms (depending on which parameter you pass to the function) i.e. it depends on whether you are doing an SHA-1 hash or a MD5 hash etc.
Information is available on the web...
e.g.
http://www.secure-hash-algorithm-md5-sha-1.co.uk/
which describes who or where the algorithms were developed and then you can look up to see if the actual specifications for them are on the web (they'll be around somewhere) e.g.
http://en.wikipedia.org/wiki/MD5
http://infohost.nmt.edu/~sfs/Students/HarleyKozushko/Presentations/MD5.pdf
http://www.uow.edu.au/~jennie/CSCI971/hash1.pdf
etc.

Could you please tell me the secret of fast graphics operations?

Could you please tell me the secret of fast graphics operations? you see I am trying to make arcade games but you don't know how my games D R A G! It is terrible! I have tried only repainting the areas that move but it still goes even slower than when I use plain old repaint();
All advice wanted.
Thanks
Joshua

It is pretty simple actually. I usually use free tools, including simple custom profiling code using System.currentTimeMillis(), and the free "hprof" heap profiler that comes with the JDK.
To run hprof, you invoke java with the -Xrunhprof parameter, in this manner:
java -Xrunhprof:cpu=samples,depth=5 -classpath (...)
my.package.MyProgramand it writes the report out to a test file when your program exits. (By default, java.hprof.txt, but see the output from java -Xrunhprof:help for how to send it somewhere else.)
To make use of the profiling data, go to the end of the file, and you will see the different stack traces and how much time they took of the total execution time.
You will want to start at the top, at the traces with the highest percentages. Now each trace has a TRACE NUMBER. So you use the summary at the end, with the percentages, to tell you which trace you're interested in.
Then go up and you will find the traces. I usually search for "TRACE: xxx" in my editor to find the one I'm looking for.
Hope this helps get you started.
Cheers,
Colin

Hi could someone please explain why the iPhone 5 is $600 dollars more expensive to buy in australia than in the US

The phones on the us site appear to me to be the unlocked phones. the contract phones are even cheaper . Australian taxes account for a 10% price diference but really all the Apple products sold in Australia are at least 30% more expensive than in the US and other markets . Why are the local (Aus) apple retailers continuing to price gouge . The ACCC must act to stop this blatant con job..
There are no options currently on the USA Apple online store site to pre-order unlocked iPhone 5's. The iPhone 5's currently available for pre-order are only availble by selecting a carrier and agreeing to a 2year contract. The prices listed are all contract-subsidized prices.
