Difference between HR programing & other module programming

Hi
What are difference between HR programming & other module programming?
This is one of interview questions from IBM.
Any body can answer for me?
WIth Regards,Jaheer.

Dear Jaheer,
Advanced Business Application Programming ABAP is SAP's fourth generation language. All of R/3's applications and even parts of its basic system are developed in ABAP. ABAP is used for customization and modification of SAP applications.
In HR ABAP use of select statements significantly less than in other areas of ABAP development, Logical databases have limited applications in other modules but are very useful in HR. Also, you really need to understand the infotype time constraint concept since the data organization in HR is Employee-Time based, When you cannot get the information that you need out of the logical DB look at the function modules starting with HR* and RH*. These function modules will provide you with multiple ways of accessing data to save time. Worst-case scenario, use a select statement.
In addition to the LDB, HR programming also involves the use of Macros for data extraction,
The storage an access of data is different,
Authorization checks.
The Human Resources module uses a system of data grouped together called infotypes. The Human Resources module uses a system of data grouped together called infotypes. And storing bulk data like time management and Payroll data in Cluster files. HR Programming involves data extraction and manipulation from these infotypes and clusters using LDB/MACRO and function modules.
Infotypes mirror a quantity of connected data records; infotypes are identifiable through a four character numerical string .
You can save the infotypes as time-dependent to enable a retroactive evaluation of Employee data.
The infotypes appear as an entry screen for the user, through which you can maintain infotype records. Infotypes can be processed individually or in fast entry mode.

What is difference between report programming and dialog programming?

hi,
what is difference between report programming and dialog programming? plz provide some example code
bye

ABAP programming
Basically reports are used to read database and represent the results in lists.
Reports are collections of processing blocks that the system calls depending on events.
We can use reports to evaluate data from database tables.
Reports are stand alone programs and controlled by events.
A report itself never creates events
steps in report:
Processing the selection screen
Reading the database
Evaluating the data and creating lists
Outputting a list.
1st u write simple logics, after that u can enhance the code as step by step.

Dialog Programming
Structure of a Dialog Program
A dialog program consists of the following basic components:
Screens (dynpros)
Each dialog in an SAP system is controlled by dynpros. A dynpro (DYnamic PROgram) consists of a screen and its flow logic and controls exactly one dialog step. The flow logic determines which processing takes place before displaying the screen (PBO-Process Before Output) and after receiving the entries the user made on the screen (PAI-Process After Input).
The screen layout fixed in the Screen Painter determines the positions of input/output fields, text fields, and graphical elements such as radio buttons and checkboxes. In addition, the Menu Painter allows to store menus, icons, pushbuttons, and function keys in one or more GUI statuses. Dynpros and GUI statuses refer to the ABAP/4 program that control the sequence of the dynpros and GUI statuses at runtime.
ABAP/4 module pool
Each dynpro refers to exactly one ABAP/4 dialog program. Such a dialog program is also called a module pool, since it consists of interactive modules. The flow logic of a dynpro contains calls of modules from the corresponding module pool. Interactive modules called at the PBO event are used to prepare the screen template in accordance to the context, for example by setting field contents or by suppressing fields from the display that are not needed. Interactive modules called at the PAI event are used to check the user input and to trigger appropriate dialog steps, such as the update task.
All dynpros to be called from within one transaction refer to a common module pool. The dynpros of a module pool are numbered. By default, the system stores for each dynpro the dynpro to be displayed next. This dynpro sequence or chain can be linear as well as cyclic. From within a dynpro chain, you can even call another dynpro chain and, after processing it, return to the original chain.

-          Format and consistancey checks for the data entered by the user.
-          Easy correction of input errors.
-          Access to data by storing it in the data bases.
screen progarmming means.dialogue programming contains.
-          Screens (Dynpros)
-          Each dialog in an SAP system is controlled by dynpros.A dynpros consists of a screen
And its flow logic and controls exactly one dialog step.
-          ABAP/4 module Pool.
     Each dynpro refers to exactly one ABAP/4 dialog program .Such a dialog program is also       called a module pool ,since it consists of interactive modules.

Differences between ABAP Programming and Dialog Programming

Can any one explain me the Differences between ABAP Programming and Dialog Programming

Hi,
ABAP PROGRAMING:
An ABAP program consists of individual ABAP statements. Each statement begins with a keyword and ends with a period.
PROGRAM FIRST_PROGRAM.
WRITE 'My First Program'.
This example contains two statements, one on each line. The keywords are PROGRAM and WRITE. The program displays a list on the screen. In this case, the list consists of the line "My First Program".
The keyword determines the category of the statement. For an overview of the different categories, refer to ABAP Statements.
You can execute different parts of programs conditionally or in loops using the standard keywords IF, CASE, DO, and WHILE.
When controlling the flow of an ABAP program, remember that the structure of the program is made up of processing blocks that cannot be nested. This section describes how to control the flow of a program within a processing block. The keywords covered here do not allow you to branch outside the processing block in which you use them. You can regard this as internal control of an ABAP program, as opposed to the external control provided by events in the ABAP runtime environment.
To control the internal flow of a processing block, you can use control structures to divide it up into smaller statement blocks according to the principles of structured programming.
DIALOG PROGRAMING:
This is a classical programming method that is based on dynpros and dialog transactions.
Classic Application Programming
Separating the application layer from the presentation layer means that when you run an ABAP application program requiring user interaction, control of the program is continually passed backwards and forwards between these layers. While a screen is ready for input, the corresponding SAP GUI of the presentation layer is active. During this time, the application layer is not active for the application program. Therefore, the ABAP application servers are free for other tasks. Once the user has entered data on the screen, program control passes back to the application layer. Now, the presentation layer is inactive. The SAP GUI is still visible to the user during this time, and it is still displaying the screen, but it cannot accept user input. The SAP GUI does not become active again until the application program has called a new screen and sent it to the presentation server.
Consequently, if you use this method, you need to divide dialog programs into single dialog steps, with each of these steps comprising the programming logic between two successive screens.

VASAVI.

Wht is the difference between unicode program and non unicode program ?

Hi guru,
wht is the difference between unicode program and non unicode program ?
Regards
Subash

About brief idea about unicode
In the past, SAP developers used various codes to encode characters of different alphabets, for example, ASCII, EBCDI, or double-byte code pages.
ASCII (American Standard Code for Information Interchange) encodes each character using 1 byte = 8 bit. This makes it possible to represent a maximum of 28 = 256 characters to which the combinations 00000000, 11111111 are assigned. Common code pages are, for example, ISO88591 for West European or ISO88595 for Cyrillic fonts.
EBCDI (Extended Binary Coded Decimal Interchange) also uses 1 byte to encode each character, which again makes it possible to represent 256 characters. EBCDIC 0697/0500 is an old IBM format that is used on AS/400 machines for West European fonts, for example.
Double-byte code pages require 1 or 2 bytes for each character. This allows you to form 216 = 65536 combinations where usually only 10,000 - 15,000 characters are used. Double-byte code pages are, for example, SJIS for Japanese and BIG5 for traditional Chinese.
Using these character sets, you can account for each language relevant to the SAP System. However, problems occur if you want to merge texts from different incompatible character sets in a central system. Equally, exchanging data between systems with incompatible character sets can result in unprecedented situations.
One solution to this problem is to use a code comprising all characters used on earth. This code is called Unicode (ISO/IEC 10646) and consists of at least 16 bit = 2 bytes, alternatively of 32 bit = 4 bytes per character. Although the conversion effort for the R/3 kernel and applications is considerable, the migration to Unicode provides great benefits in the long run:
The Internet and consequently also mySAP.com are entirely based on Unicode, which thus is a basic requirement for international competitiveness.
Unicode allows all R/3 users to install a central R/3 System that covers all business processes worldwide.
Companies using different distributed systems frequently want to aggregate their worldwide corporate data. Without Unicode, they would be able to do this only to a limited degree.
With Unicode, you can use multiple languages simultaneously at a single frontend computer.
Unicode is required for cross-application data exchange without loss of data due to incompatible character sets. One way to present documents in the World Wide Web (www) is XML, for example.
ABAP programs must be modified wherever an explicit or implicit assumption is made with regard to the internal length of a character. As a result, a new level of abstraction is reached which makes it possible to run one and the same program both in conventional and in Unicode systems. In addition, if new characters are added to the Unicode character set, SAP can decide whether to represent these characters internally using 2 or 4 bytes.
A Unicode-enabled ABAP program (UP) is a program in which all Unicode checks are effective. Such a program returns the same results in a non-Unicode system (NUS) as in a Unicode system (US). In order to perform the relevant syntax checks, you must activate the Unicode flag in the screens of the program and class attributes.
In a US, you can only execute programs for which the Unicode flag is set. In future, the Unicode flag must be set for all SAP programs to enable them to run on a US. If the Unicode flag is set for a program, the syntax is checked and the program executed according to the rules described in this document, regardless of whether the system is a US or an NUS. From now on, the Unicode flag must be set for all new programs and classes that are created.
If the Unicode flag is not set, a program can only be executed in an NUS. The syntactical and semantic changes described below do not apply to such programs. However, you can use all language extensions that have been introduced in the process of the conversion to Unicode.
As a result of the modifications and restrictions associated with the Unicode flag, programs are executed in both Unicode and non-Unicode systems with the same semantics to a large degree. In rare cases, however, differences may occur. Programs that are designed to run on both systems therefore need to be tested on both platforms.

What is the difference between subroutine and function module?

What is the difference between subroutine and function module?

Hi,
they can both return values.
FMs are mainly used when a routine is to be performed by many programs.
Subroutines (forms) are generally only executed within one program.
You can perform routines from other programs, but it's not often done.
both forms and FMs are reusable modularization units.
To distinguish we generally say that forms are used for internal modularization and
FMs are used for external modularization.
To decide on which to implement, consider whether you need the content to be used just for a limited program
or wheteher it can be called from many independent programs.
For the first purpose it is better to implement a form whereas for the second we implement an FM.
However, ABAP does not isolate the usage context.
That is; you can call a form from another program within whose code the form is not actually implemented.
However, this requires attention since the form may utilize global variables.
The same issue holds for FMs.
FMs are encapsulated in function groups and function groups may have global variables that can be globally
used by all FMs inside it.
Thanks,

What is the difference between the normal function module and bapi function

hi,
what is the difference between the normal function module and bapi function module.

Hi
BAPI stands for Business API(Application Program Interface).
A BAPI is remotely enabled function module ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
You can make your function module remotely enabled in attributes of Function module but
A BAPI are standard SAP function modules provided by SAP for remote access. Also they are part of Businees Objest Repository(BOR).
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.

Difference between screen painter and module pool

Hi guys,
what's the difference between SCREEN PAINTER and MODULE POOL ....
can anyone plz give brief description ...
regards
venu

hi ,
As its said by many colleagues in SDN , there are not very major differences between Modulepools and screen painter .
The few differences are :
1) Module pool is nothing but a pool ( series ) of screens . and Screen painter ( SE51 ) is a tool used for creating/designing screens .
2) While creating a modulepool you even need to create a transaction and assign this module pool program else the mpool program doesnt work . I think this is place we can say they are different .
3) If at all you create a screen in screen painter ( SE51 ) , that doesnot function by its own , you need to assign it to any of the executable programs or modulepool programs .Here is again a difference .

One more thing, if you do not have the hard drive icon on the desktop you can get it there by:
click on the desktop so the menu bar says Finder next to the apple logo, click Finder, then Preferences, General, Show These Items on desktop and check the hard disks:
That makes life a lot easier when you want to find out information.

What are the differences between Oracle and other NoSQL database

Hi all,
I would like to know what the differences between Oracle and other NoSQL database are.
When and why should we use Oracle?
Is Oracle NoSQL database link with Big Data Appliance?
Can we use map-reduce on a single personal computer? How should we install Oracle NoSQL database to use map reduce on a single personal computer?
Do we also have eventual consistency with Oracle NoSQL database? Can we lose data if master node fails?
Are transactions ACID with Oracle NoSQL database? How can we prove it?
Thanks.

http://www.oracle.com/technetwork/database/nosqldb/overview/index.html
Is Oracle NoSQL database link with Big Data Appliance?Yes, Oracle NoSQL Database will be a component of the Big Data Appliance.
Can we use map-reduce on a single personal computer? How should we install Oracle NoSQL database to use map reduce on a single personal computer?Yes, I believe you can run M/R on a single computer. Consult the various pieces of documentation available on the web. You may run Oracle NoSQL Database on the same computer that you are running M/R on, but it is likely that they will compete for CPU and IO resources and therefore performance may suffer.
Do we also have eventual consistency with Oracle NoSQL database? Yes.
Can we lose data if master node fails?If you run Oracle NoSQL Database with the default (recommended) durability settings, then if the master fails, a new one will be elected and data is not lost.
Are transactions ACID with Oracle NoSQL database? How can we prove it?Yes, each operation is executed in an ACID transaction. The API has the concept of "multi" operations which allow the caller to perform multiple operations on sets of records with the same major key, but different minor keys. Those operations are also performed within a transaction.

I appreciate it.
Thanks!

HI,
See these links on help.sap.com
For BAPI:
The data entered in the Internet is transferred to the R/3 System via BAPIs (Business Application Programming Interfaces).
Data in the R/3 System is accessed via BAPIs as well.
