Difference between dialog programming and module pool programming

Hi all ,
Is there any differnce between module pool programming and dialog programming .
thanks in advance ,
magesh anandan

Mahesh,
    Both are same.
MODULE POOL : Through modules only we have access ABAP EDITOR
                               from FLOW LOGIC EDITOR .
DIALOG PROGRAMING : We use to have dialogs(Screen process) to interact
                                       with user .
Pls. reward if useful

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 .

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.

Dialog programming and module-pool programming

Can someone tell em the difference between dialog programming and module-pool programming ?

Hi Vinod ,
Actually Dialog Programming is Module pool Programming.
Please go thru this , see if your dbout gets clear.
Basic components of dialog program?
- 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.
REGARDS,
VASAVI.

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.

VIjay

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.
You can also check out these official SAP locations on the SAP Service Marketplace:

Wat is the exact differences between clustered table and pooled table

hi,
can you tell me ravi...wat is the exact differences between clustered table and pooled table
with regards//
anilreddyg

Hi Anil Reddy
Pooled Tables, Table Pools, Cluster Tables, and Table Clusters
These types of tables are not transparent in the sense that they are not legible or manageable directly using the underlying database system tools. They are managed from within the R/3 environment from the ABAP dictionary and also at runtime when they are loaded into application memory.Pool and cluster tables are logical tables. Physically, these logical tables are arranged as records of transparent tables. The pool and cluster tables are grouped together in other tables, which are of the transparent type. The tables that group together pool tables are known as table pools, or just pools; similarly, table clusters, or just
clusters, are the tables which group cluster tables.Not all operations that can be performed over transparent tables can be executed over pool or cluster tables.
For instance, you can manage these tables using Open SQL calls from ABAP, but not Native SQL.These tables are meant to be buffered and loaded in memory, because they are commonly used for storing internal control information and other types of data with no external (business) relevance. SAP recommends that tables of pool or cluster type be used exclusively for control information such as
program parameters, documentation, and so on. Transaction and application data should be stored in transparent tables.
Table Pools
From the point of view of the underlying DBMS as from the point of view of the ABAP dictionary, a table pool is a transparent table containing a group of pooled tables which, when created, were assigned to this table pool.
Field Type Description
TABNAME CHAR(10) Table name
VARKEY CHAR(n) Maximum key length n =< 110
DATALN INT2(5) Length of the VARDATA record returned
VARDATA RAW(m) Maximum length of the data varies according to DBMS
Table Clusters
Similarly to pooled tables, cluster tables are logical tables which, when created, are assigned to a table cluster. Therefore, a table cluster, or just cluster, groups together several tables of type clusters.Several logical rows from different cluster tables are brought together in a single physical record. The records
from the cluster tables assigned to a cluster are thus stored in a single common table in the database.A cluster contains a transparent cluster key which must be located at the start of the key of all logical cluster tables to be included in the cluster. As well, a cluster contains a long field (VARDATA), which contains the
data of the cluster tables for this key. If the data does not fit into a field, continuation records are created.
Field Type Description
CLKEY1 CHAR(*) First key fields
CLKEY2 CHAR(*) Second key field
CLKEYN CHAR(*) nth key field
PAGENO INT2(5) Number of the next page
TIMESTMP CHAR(14) Time stamp
PAGELG INT2(5) Length of the VARDATA record returned
VARDATA RAW(*) Maximum length of the data section; varies according to database system
Working with Tables
The dictionary includes many functions for working with tables. There are five basic operations you can perform on tables: display, create, delete, modify, copy. Please do not confuse displaying a table with displaying the table entries (table contents). In order to display a table, it must previously exist; otherwise the system will display an error message in the status bar. For the following example, the table TABNA is used. To display this table, from the main dictionary screen, enter the table name in the Object name
input field with the radio button selected next to Tables. Then, click on the Display button at the bottom of the screen, or press the F7 function key, or, alternatively,
select Dictionary object Display from the menu.
In this screen, you can see table information such as
¨ Table type, shown next to the name of the object. In the example, it is a transparent table.
¨ Short text description.
¨ Name of the user who made the last change, and the date of the change.
¨ Master language.
¨ Table status. On the screen, you can see this table is saved and active.
¨ Development class. For information on development classes, refer to Chap. 6.
Delivery class, which sets the maintenance group for the table. It controls how tables will behave during client copy procedures, upgrades, and so forth.¨
Tab. Maint. Allowed flag, which indicates whether you can generate a screen for maintaining table entries.
¨Then, on the lower part of the screen, you can see the table fields with all associated characteristics such as:
¨ Field name.
¨ Key indicator. When set, this field is the primary key, or part of it.
¨ Data element.
¨ Basic data type.
¨ Length.
¨ Check table.
¨ Short text, describing the field.
Additional information about the table can be displayed by selecting the corresponding functions from the menu or directly from the application toolbar, such as keys, indexes, or technical settings
Standard table:
The key access to a standard table uses a sequential search. The time required for an access is linearly dependent on the number of entries in the internal table.
You should usually access a standard table with index operations.
Sorted table:
The table is always stored internally sorted by its key. Key access to a sorted table can therefore use a binary search. If the key is not unique, the entry with the lowest index is accessed. The time required for an access is logarithmically dependent on the number of entries in the internal table.
Index accesses to sorted tables are also allowed. You should usually access a sorted table using its key.
Hash table:
The table is internally managed with a hash procedure. All the entries must have a unique key. The time required for a key access is constant, that is it does not depend on the number of entries in the internal table.
You cannot access a hash table with an index. Accesses must use generic key operations (SORT, LOOP, etc.).
Index table:
The table can be a standard table or a sorted table.
Index access is allowed to such an index table. Index tables can be used to define the type of generic parameters of a FORM (subroutine) or a function module.

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.
