Difference between Submit Button and Button

Hi,
Please help me understanding the difference bewteen the following cases.
1) Submit Button + ActionType : None
2) Submit Button + Action Type :fire partial action
3) Submit Button + Action Type : Fire Action
4) Button + Action Type : fireAction
5) Button + Action Type : firePartialAction
My Understanding is 1st and 4th Both submits the form.
Also, please let me know, is it a valid scenario where we use the SubmitButton and still gives ActionType. What difference it makes when action type is given with submit button.
I understand that when we use 4th then it submits the form and whereas in case of 5th it doesnt.
Thanks in advance

Hi,
Thanks for your replies.
Actually i wanted to understand this in context of the issue we are facing.
We have a text field and a button besides it. We have a TAB OUT even associated with the text field which is captured using firePartialAction event. Also, the button is a SUBMIT BUTTON with a partialFireAction associated with it.
1) When you give % in textfield and tab out a popups come and load the data in a table - WORKS FINE
2) When you dont enter anything in textfiled and clicks on the button, same popups comes and loads data into the table. - WORKS FINE
3) When you give % in Text Field and clicks on the BUTTON, from JDEV, we verified that TAB OUT event gets triggered.Once that event is over, we can see the HOUR GLASS which doesnt go away. --- ISSUE
Resolution Tested : When i just remove ACTIONTYPE from button and do NAVIGATION - 3, issue is resolved.
Also, if i make that button as BUTTON and give FIRE ACTION, issue is resolved.
Now the main concern is the same combination SUBMIT BUTTON and ACTIONTYPE: firePartialAction works fine in 11i and causes issue in R12.
Please let me know your comments.
Thanks in advance

  • Difference between Session method and call transaction

    Hi,
    please give me the differences between session method and call transaction,
    briefly explaining synchronus , asynchronus, process, update.
    Thanks in advance

    Hi Vijay Kumar
    CLASSICAL BATCH INPUT (Session Method)
    CALL TRANSACTION
    BATCH INPUT METHOD:
    This method is also called as ‘CLASSICAL METHOD’.
    Features:
    Asynchronous processing.
    Synchronous Processing in database update.
    Transfer data for more than one transaction.
    Batch input processing log will be generated.
    During processing, no transaction is started until the previous transaction has been written to the database.
    CALL TRANSACTION METHOD :
    This is another method to transfer data from the legacy system.
    Features:
    Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
    Updating the database can be either synchronous or asynchronous. The program specifies the update type.
    Transfer data for a single transaction.
    Transfers data for a sequence of dialog screens.
    No batch input processing log is generated.

    Among the two methods call transaction is better compared to session bcoz data transfer is faster in it.
    Differences between call transaction and session.
    Session Method:
    1) Data is not updated in the database table until the session is processed.
    2) No sy-subrc is returned.
    3) Error log is created for error records.
    4) Updation is always synchronous.
    Call Transaction Method:
    1) Immediate updation in the database table.
    2) sy-subrc is returned.
    3)Error need to be handled explicitly.
    4) updation can be synchronous as well as asynchronous.
    2) ya u can use using the N mode no screen.
    3)u can't handle multiple transaction in call transaction.
    4) u can handle multiple transaction in session using the BDC_INSERT fm.
    5)When u go to SM35 u can able to see the error records.
    Which is best?
    That depends on your requirement. Both of them have there advantages.
    According to the situation u can choose any one of these.
    difference between batch input and call transaction in BDC Session method.
    1) synchronous processing.
    2) can tranfer large amount of data.
    3) processing is slower.
    4) error log is created
    5) data is not updated until session is processed.
    Call transaction.
    1) asynchronous processing
    2) can transfer small amount of data
    3) processing is faster.
    4) errors need to be handled explicitly
    5) data is updated automatically
    For session method,these are the function modules to b used.
    BDC_OPEN_GROUP
    BDC_INSERT
    BDC_CLOSE_GROUP
    For call transaction,this is the syntax.
    CALL TRANSACTION TCODE USING BDCDATA
    MODE A or E or N
    UPDATE A or S
    MESSAGES INTO MESSTAB.
    Take a scenario where we need to post documents in FB01 and the input file has say 2000 records (2000 documents, not line items in FB01 but 2000 records)
    In the BDC call transaction method
    We call the transaction FB01 2000 times (once for each record posting) and if the processing fails in record no 3 it can be captured and start with reocord 4.
    Eg: Loop at itab.
    call transaction FB01
    capture errors
    endloop.
    In the session method.
    We do not explicity call the transaction 2000 times, but all the records are appeneded into a session and this session is stored. The processinf of the session is done wwhenever the user wants it to be done. Hence the errors cannot be captured in the program itself

    http://www.planetsap.com/bdc_main_page.htm
    Batch Input Session method is asynchronous as told by others here. But the advantage of this is that you have all the error messages and the data for each transaction held persistantly. You don't have to code anything for processing them or writing the logs.
    But at the same time, the same feature can be disadvantageous if you need to react to an error or if there are too many errors to manually correct in a session. Since the session are created in the program and its execution is done seperately, you loose the trackability of such transactions.
    With a call transaction, what was a disadvantage above will become an advantage. Call transaction immediately gives you messages back and you can react to it in your program. But the disadvantage is that, if you have several hundreds of transactions to run, running them from within the program can be resource crunching affair. It will hamper the system performance and you cannot really distribute the load. Of course, you have some mechanisms with which you can overcome this, but you will have to code for it. Also, storing the messages and storing the errored transaction data etc will have to be handled by you in the program. Whereas, in batch input session, your program's job is to just create the session, after that everything is standard SAP system's responsibility.
    Ideally, you should do a call transaction if the resources are not a problem and if it fails, put the errored transaction into a session.
    You can decide based on the data volume that your BDC is processing. If data volume is high go for session else call transaction will do.The call transaction updates will be instantaneous where as session needs to be processed explictly after creation.
    Session Method
    1) Session method supports both small amount of data aswell as large amount of data
    2) data processing is asynchronus and data updation is synchronus.
    3) it process multiple apllication while perfomaning validations.
    4) in session method data will be updated in data base only after processing session only.
    5) system provide by default logfile for handling error records.
    6) it supports both foreground aswell as background process
    in bdc we use FM ...
    bdc_open_group " for creating Session
    bdc_insert " adding transaction and bdcdata table for updating database
    bdc_close_group " for closing Session
    Call Transaction
    1) Call transaction exclusively for small amout of data
    2) it supports only one apllication while perfoming validations
    3) there is no default logfile, We can explicitly provide logic for creating logfile for handling error records.
    we can create logfile by using structure....BDCMSGCOLL
    4) it doesn't support background processing.
    5) data processing is synchronous and Data updation is Synchronous( default), in
    this method also supports daya updation in asynchronus process also.
    syntax:
    Call transaction <transaction-name> using BDCDATA
    mode <A/N/E>
    update <L/A/S>
    messages into BDCMSGCOLL.
    BDC:
    Batch Data Communication (BDC) is the process of transferring data from one SAP System to another SAP system or from a non-SAP system to SAP System.
    Features :
    BDC is an automatic procedure.
    This method is used to transfer large amount of data that is available in electronic medium.
    BDC can be used primarily when installing the SAP system and when transferring data from a legacy system (external system).
    BDC uses normal transaction codes to transfer data.
    Types of BDC :
    CLASSICAL BATCH INPUT (Session Method)
    CALL TRANSACTION
    BATCH INPUT METHOD:
    This method is also called as ‘CLASSICAL METHOD’.
    Features:
    Asynchronous processing.
    Synchronous Processing in database update.
    Transfer data for more than one transaction.
    Batch input processing log will be generated.
    During processing, no transaction is started until the previous transaction has been written to the database.
    CALL TRANSACTION METHOD :
    This is another method to transfer data from the legacy system.
    Features:
    Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
    Updating the database can be either synchronous or asynchronous. The program specifies the update type.
    Transfer data for a single transaction.
    Transfers data for a sequence of dialog screens.
    No batch input processing log is generated.

    Hi
    Core ABAP (procedural) works with Event driven, subroutine driven one
    OOPS ABAP works on the OOPS concepts like Inheritance, polymorphism,abstraction and encapsulation.
    see the doc
    ABAP is one of many application-specific fourth-generation languages (4GLs) first developed in the 1980s. It was originally the report language for SAP R/2, a platform that enabled large corporations to build mainframe business applications for materials management and financial and management accounting. ABAP used to be an abbreviation of Allgemeiner Berichtsaufbereitungsprozessor, the German meaning of "generic report preparation processor", but was later renamed to Advanced Business Application Programming. ABAP was one of the first languages to include the concept of Logical Databases (LDBs), which provides a high level of abstraction from the basic database level.
    The ABAP programming language was originally used by SAP developers to develop the SAP R/3 platform. It was also intended to be used by SAP customers to enhance SAP applications – customers can develop custom reports and interfaces with ABAP programming. The language is fairly easy to learn for programmers but it is not a tool for direct use by non-programmers. Good programming skills, including knowledge of relational database design and preferably also of object-oriented concepts, are required to create ABAP programs.
    ABAP remains the language for creating programs for the client-server R/3 system, which SAP first released in 1992. As computer hardware evolved through the 1990s, more and more of SAP's applications and systems were written in ABAP. By 2001, all but the most basic functions were written in ABAP. In 1999, SAP released an object-oriented extension to ABAP called ABAP Objects, along with R/3 release 4.6.
    SAP's most recent development platform, NetWeaver, supports both ABAP and Java.
    Implementation
    Where does the ABAP Program Run?
    All ABAP programs reside inside the SAP database. They are not stored in separate external files like Java or C++ programs. In the database all ABAP code exists in two forms: source code, which can be viewed and edited with the ABAP workbench, and "compiled" code ("generated" code is the more correct technical term), which is loaded and interpreted by the ABAP runtime system. Code generation happens implicitly when a unit of ABAP code is first invoked. If the source code is changed later or if one of the data objects accessed by the program has changed (e.g. fields were added to a database table), then the code is automatically regenerated.
    ABAP programs run in the SAP application server, under control of the runtime system, which is part of the SAP kernel. The runtime system is responsible for processing ABAP statements, controlling the flow logic of screens and responding to events (such as a user clicking on a screen button). A key component of the ABAP runtime system is the Database Interface, which turns database-independent ABAP statements ("Open SQL") into statements understood by the underlying DBMS ("Native SQL"). The database interface handles all the communication with the relational database on behalf of ABAP programs; it also contains extra features such as buffering of frequently accessed data in the local memory of the application server.
    Basis
    Basis sits between ABAP/4 and Operating system.Basis is like an operating system for R/3. It sits between the ABAP/4 code and the computer's operating system. SAP likes to call it middleware because it sits in the middle, between ABAP/4 and the operating system. Basis sits between ABAP/4 and the operating system. ABAP/4 cannot run directly on an operating system. It requires a set of programs (collectively called Basis) to load, interpret, and buffer its input and output. Basis, in some respects, is like the Windows environment. Windows starts up, and while running it provides an environment in which Windows programs can run. Without Windows, programs written for the Windows environment cannot run. Basis is to ABAP/4 programs as Windows is to Windows programs. Basis provides the runtime environment for ABAP/4 programs. Without Basis, ABAP/4 programs cannot run. When the operator starts up R/3, you can think of him as starting up Basis. Basis is a collection of R/3 system programs that present you with an interface. Using this interface the user can start ABAP/4 programs. To install Basis, an installer runs the program r3inst at the command-prompt level of the operating system. Like most installs, this creates a directory structure and copies a set of executables into it. These executables taken together as a unit form Basis.
    To start up the R/3 system, the operator enters the startsap command. The Basis executables start up and stay running, accepting requests from the user to run ABAP/4 programs.
    ABAP/4 programs run within the protective Basis environment; they are not executables that run on the operating system. Instead, Basis reads ABAP/4 code and interprets it into operating system instructions. ABAP/4 programs do not access operating system functions directly. Instead, they use Basis functions to perform file I/O and display data in windows. This level of isolation from the operating system enables ABAP/4 programs to be ported without modification to any system that supports R/3. This buffering is built right into the ABAP/4 language itself and is actually totally transparent to the programmer.
    Basis makes ABAP/4 programs portable. The platforms that R/3 can run on are shown in Table. For example, if you write an ABAP/4 program on Digital UNIX with an Informix database and an OSF/Motif interface, that same program should run without modification on a Windows NT machine with an Oracle database and a Windows 95 interface. Or, it could run on an AS/400 with a DB2 database using OS/2 as the front-end.
    SAP also provides a suite of tools for administering the Basis system. These tools perform tasks such as system performance monitoring, configuration, and system maintenance. To access the Basis administration tools from the main menu, choose the path Tools->Administration.

    SAP Systems and Landscapes
    All SAP data exists and all SAP software runs in the context of an SAP system. A system consists of a central relational database and one or more application servers ("instances") accessing the data and programs in this database. A SAP system contains at least one instance but may contain more, mostly for reasons of sizing and performance. In a system with multiple instances, load balancing mechanisms ensure that the load is spread evenly over the available application servers.
    Installations of the Web Application Server (landscapes) typically consist of three systems: one for development, one for testing and quality assurance, and one for production. The landscape may contain more systems, e.g. separate systems for unit testing and pre-production testing, or it may contain fewer, e.g. only development and production, without separate QA; nevertheless three is the most common configuration. ABAP programs are created and undergo first testing in the development system. Afterwards they are distributed to the other systems in the landscape. These actions take place under control of the Change and Transport System (CTS), which is responsible for concurrency control (e.g. preventing two developers from changing the same code at the same time), version management and deployment of programs on the QA and production systems.
    The Web Application Server consists of three layers: the database layer, the application layer and the presentation layer. These layers may run on the same or on different physical machines. The database layer contains the relational database and the database software. The application layer contains the instance or instances of the system. All application processes, including the business transactions and the ABAP development, run on the application layer. The presentation layer handles the interaction with users of the system. Online access to ABAP application servers can go via a proprietary graphical interface, the SAPGUI, or via a Web browser.
    Transactions
    We call an execution of an ABAP program using a transaction code a transaction. There are dialog, report, parameter, variant, and as of release 6.10, OO transactions. A transaction is started by entering the transaction code in the input field on the standard toolbar, or by means of the ABAP statements CALL TRANSACTION or LEAVE TO TRANSACTION. Transaction codes can also be linked to screen elements or menu entries. Selecting such an element will start the transaction.
    A transaction code is simply a twenty-character name connected with a Dynpro, another transaction code, or, as of release 6.10, a method of an ABAP program. Transaction codes linked with Dynpros are possible for executable programs, module pools, and function groups. Parameter transactions and variant transactions are linked with other transaction codes. Transaction codes that are linked with methods are allowed for all program types that can contain methods. Transaction codes are maintained in transaction SE93.
    So, a transaction is nothing more than the SAP way of program execution—but why is it called “transaction”? ABAP is a language for business applications and the most important features of business applications were and still are are transactions. Since in the early days of SAP, the execution of a program often meant the same thing as carrying out a business transaction, the terms transaction and transaction code were chosen for program execution. But never mix up the technical meaning of a transaction with business transactions. For business transactions, it is the term LUW (Logical Unit of Work) that counts. And during one transaction (program execution), there can be many different LUW’s.
    Let’s have a look at the different kind of transactions:
    Dialog Transaction
    These are the most common kind of transactions. The transaction code of a dialog transaction is linked to a Dynpro of an ABAP program. When the transaction is called, the respective program is loaded and the Dynpro is called. Therefore, a dialog transaction calls a Dynpro sequence rather than a program. Only during the execution of the Dynpro flow logic are the dialog modules of the ABAP program itself are called. The program flow can differ from execution to execution. You can even assign different dialog transaction codes to one program.
    Parameter Transaction
    In the definition of a parameter transaction code, a dialog transaction is linked with parameters. When you call a parameter transaction, the input fields of the initial Dynpro screen of the dialog transaction are filled with parameters. The display of the initial screen can be inhibited by specifying all mandatory input fields as parameters of the transaction.
    Variant Transaction
    In the definition of a variant transaction code, a dialog transaction is linked with a transaction variant. When a variant transaction is accessed, the dialog transaction is called and executed with the transaction variant. In transaction variants, you can assign default values to the input fields on several Dynpro screens in a transaction, change the attributes of screen elements, and hide entire screens. Transaction variants are maintained in transaction SHD0.
    Report Transaction
    A report transaction is the transaction code wrapping for starting the reporting process. The transaction code of a report transaction must be linked with the selection screen of an executable program. When you execute a report transaction, the runtime environment internally executes the ABAP statement SUBMIT—more to come on that.
    OO Transaction
    A new kind of transaction as of release 6.10. The transaction code of an OO transaction is linked with a method of a local or global class. When the transaction is called, the corresponding program is loaded, for instance methods an object of the class is generated and the method is executed.
    Types of ABAP programs
    In ABAP, there are two different types of programs:
    Report programs(Executable pools)
    A Sample ReportReport programs AKA Executable pools follow a relatively simple programming model whereby a user optionally enters a set of parameters (e.g. a selection over a subset of data) and the program then uses the input parameters to produce a report in the form of an interactive list. The output from the report program is interactive because it is not a passive display; instead it enables the user, through ABAP language constructs, to obtain a more detailed view on specific data records via drill-down functions, or to invoke further processing through menu commands, for instance to sort the data in a different way or to filter the data according to selection criteria. This method of presenting reports has great advantages for users who must deal with large quantities of information and must also have the ability to examine this information in highly flexible ways, without being constrained by the rigid formatting or unmanageable size of "listing-like" reports. The ease with which such interactive reports can be developed is one of the most striking features of the ABAP language.
    The term "report" is somewhat misleading in the sense that it is also possible to create report programs that modify the data in the underlying database instead of simply reading it.
    A customized screen created using Screen Painter,which is one of the tool available in ABAP workbench(T-code = SE51).
    Online programs
    Online programs (also called module pools) do not produce lists. These programs define more complex patterns of user interaction using a collection of screens. The term “screen” refers to the actual, physical image that the users sees. Each screen also has a “flow logic”; this refers to the ABAP code invoked by the screens, i.e. the logic that initializes screens, responds to a user’s requests and controls the sequence between the screens of a module pool. Each screen has its own Flow Logic, which is divided into a "PBO" (Process Before Output) and "PAI" (Process After Input) section. In SAP documentation the term “dynpro” (dynamic program) refers to the combination of the screen and its Flow Logic.
    Online programs are not invoked directly by their name, but are associated with a transaction code. Users can then invoke them through customizable, role-dependent, transaction menus.
    Apart from reports and online programs, it is also possible to develop sharable code units such as class libraries, function libraries and subroutine pools.
    Subroutine Pools
    Subroutine pools, as the name implies, were created to contain selections of subroutines that can be called externally from other programs. Before release 6.10, this was the only way subroutine pools could be used. But besides subroutines, subroutine pools can also contain local classes and interfaces. As of release 6.10, you can connect transaction codes to methods. Therefore, you can now also call subroutine pools via transaction codes. This is the closest to a Java program you can get in ABAP: a subroutine pool with a class containing a method – say – main connected to a transaction code!
    Type Pools
    Type pools are the precursors to general type definitions in the ABAP Dictionary. Before release 4.0, only elementary data types and flat structures could be defined in the ABAP Dictionary. All other types that should’ve been generally available had to be defined with TYPES in type pools. As of release 4.0, type pools were only necessary for constants. As of release 6.40, constants can be declared in the public sections of global classes and type pools can be replaced by global classes.
    Class Pools
    Class pools serve as containers for exactly one global class. Besides the global class, they can contain global types and local classes/interfaces to be used in the global class. A class pool is loaded into memory by using one of its components. For example, a public method can be called from any ABAP program or via a transaction code connected to the method. You maintain class pools in the class builder.
    Interface Pools
    Interface pools serve as containers for exactly one global interface—nothing more and nothing less. You use an interface pool by implementing its interface in classes and by creating reference variables with the type of its interface. You maintain interface pools in the class builder.
    ABAP Workbench
    The ABAP Workbench contains different tools for editing Repository objects. These tools provide you with a wide range of assistance that covers the entire software development cycle. The most important tools for creating and editing Repository objects are:
    ABAP Editor for writing and editing program code
    ABAP Dictionary for processing database table definitions and retrieving global types
    Menu Painter for designing the user interface (menu bar, standard toolbar, application toolbar, function key assignment)
    Screen Painter for designing screens (dynamic programs) for user dialogs
    Function Builder for displaying and processing function modules (routines with defined interfaces that are available throughout the system)
    Class Builder for displaying and processing ABAP Objects classes
    The ABAP Dictionary
    Enforces data integrity
    Manages data definitions without redundancy
    Is tightly integrated with the rest of the ABAP/4 Development Workbench.
    Enforcing data integrity is the process of ensuring that data entered into the system is logical, complete, and consistent. When data integrity rules are defined in the ABAP/4 Dictionary, the system automatically prevents the entry of invalid data. Defining the data integrity rules at the dictionary level means they only have to be defined once, rather than in each program that accesses that data.
    The following are examples of data lacking integrity:
    A date field with a month value of 13
    An order assigned to a customer number that doesn’t exist
    An order not assigned to a customer
    Managing data definitions without redundancy is the process of linking similar information to the same data definition. For example, a customer database is likely to contain a customer’s ID number in several places. The ABAP Dictionary provides the capability of defining the characteristics of a customer ID number in only one place. That central definition then can be used for each instance of a customer ID number.
    The ABAP Dictionary’s integration with the rest of the development environment enables ABAP programs to automatically recognize the names and characteristics of dictionary objects.
    Additionally, the system provides easy navigation between development objects and dictionary definitions. For example, as a programmer, you can double-click on the name of a dictionary object in your program code, and the system will take you directly to the definition of that object in the ABAP/4 Dictionary.
    When a dictionary object is changed, a program that references the changed object will automatically reference the new version the next time the program runs. Because ABAP is interpreted, it is not necessary to recompile programs that reference changed dictionary objects.

    The syntax of the ABAP programming language consists of the following elements:
    Statements
    An ABAP program consists of individual ABAP statements. Each statement begins with a keyword and ends with a period.
    "Hello World" PROGRAM
    WRITE 'Hello World'.
    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.
    Formatting ABAP Statements
    ABAP has no format restrictions. You can enter statements in any format, so a statement can be indented, you can write several statements on one line, or spread a single statement over several lines.
    You must separate words within a statement with at least one space. The system also interprets the end of line marker as a space.
    The program fragment
    PROGRAM TEST.
    WRITE 'This is a statement'.
    could also be written as follows:
    PROGRAM TEST. WRITE 'This is a statement'.
    or as follows:
    PROGRAM
    TEST.
    WRITE
    'This is a statement'.
    Use this free formatting to make your programs easier to understand.
    Special Case: Text Literals
    Text literals are sequences of alphanumeric characters in the program code that are enclosed in quotation marks. If a text literal in an ABAP statement extends across more than one line, the following difficulties can occur:
    All spaces between the quotation marks are interpreted as belonging to the text literal. Letters in text literals in a line that is not concluded with quotation marks are interpreted by the editor as uppercase. If you want to enter text literals that do not fit into a single line, you can use the ‘&’ character to combine a succession of text literals into a single one.
    The program fragment
    PROGRAM TEST.
    WRITE 'This
    is
    a statement'.
    inserts all spaces between the quotation marks into the literal, and converts the letters to uppercase.
    This program fragment
    PROGRAM TEST.
    WRITE 'This' &
    ' is ' &
    'a statement'.
    combines three text literals into one.
    Chained Statements
    The ABAP programming language allows you to concatenate consecutive statements with an identical first part into a chain statement.
    To concatenate a sequence of separate statements, write the identical part only once and place a colon ( after it. After the colon, write the remaining parts of the individual statements, separating them with commas. Ensure that you place a period (.) after the last part to inform the system where the chain ends.
    Statement sequence:
    WRITE SPFLI-CITYFROM.
    WRITE SPFLI-CITYTO.
    WRITE SPFLI-AIRPTO.
    Chain statement:
    WRITE: SPFLI-CITYFROM, SPFLI-CITYTO, SPFLI-AIRPTO.
    In the chain, a colon separates the beginning of the statement from the variable parts. After the colon or commas, you can insert any number of spaces.
    You could, for example, write the same statement like this:
    WRITE: SPFLI-CITYFROM,
    SPFLI-CITYTO,
    SPFLI-AIRPTO.
    In a chain statement, the first part (before the colon) is not limited to the keyword of the statements.
    Statement sequence:
    SUM = SUM + 1.
    SUM = SUM + 2.
    SUM = SUM + 3.
    SUM = SUM + 4.
    Chain statement:
    SUM = SUM + : 1, 2, 3, 4.
    Comments
    Comments are texts that you can write between the statements of your ABAP program to explain their purpose to a reader. Comments are distinguished by the preceding signs * (at the beginning of a line) and " (at any position in a line). If you want the entire line to be a comment, enter an asterisk (*) at the beginning of the line. The system then ignores the entire line when it generates the program. If you want part of a line to be a comment, enter a double quotation mark (") before the comment. The system interprets comments indicated by double quotation marks as spaces.

    Advantages of ABAP over Contemporary languages
    ABAP OBJECTS
    Object orientation in ABAP is an extension of the ABAP language that makes available the advantages of object-oriented programming, such as encapsulation, interfaces, and inheritance. This helps to simplify applications and make them more controllable.
    ABAP Objects is fully compatible with the existing language, so you can use existing statements and modularization units in programs that use ABAP Objects, and can also use ABAP Objects in existing ABAP programs.
    ABAP Statements – an Overview
    The first element of an ABAP statement is the ABAP keyword. This determines the category of the statement. The different statement categories are as follows:
    Declarative Statements
    These statements define data types or declare data objects which are used by the other statements in a program or routine. The collected declarative statements in a program or routine make up its declaration part.
    Examples of declarative keywords:
    TYPES, DATA, TABLES
    Modularization Statements
    These statements define the processing blocks in an ABAP program.
    The modularization keywords can be further divided into:
    · Defining keywords
    You use statements containing these keywords to define subroutines, function modules, dialog modules and methods. You conclude these processing blocks using the END statements.
    Examples of definitive keywords:
    METHOD ... ENDMETHOD, FUNCTION ... ENDFUNCTION, MODULE ... ENDMODULE.
    · Event keywords
    You use statements containing these keywords to define event blocks. There are no special statements to conclude processing blocks - they end when the next processing block is introduced.
    Examples of event key words:
    AT SELECTION SCREEN, START-OF-SELECTION, AT USER-COMMAND
    Control Statements
    You use these statements to control the flow of an ABAP program within a processing block according to certain conditions.
    Examples of control keywords:
    IF, WHILE, CASE
    Call Statements
    You use these statements to call processing blocks that you have already defined using modularization statements. The blocks you call can either be in the same ABAP program or in a different program.
    Examples of call keywords:
    CALL METHOD, CALL TRANSACTION, SUBMIT, LEAVE TO
    Operational Statements These keywords process the data that you have defined using declarative statements.
    Examples of operational keywords:
    MOVE, ADD
    Unique Concept of Internal Table in ABAP
    Internal tables provide a means of taking data from a fixed structure and storing it in working memory in ABAP. The data is stored line by line in memory, and each line has the same structure. In ABAP, internal tables fulfill the function of arrays. Since they are dynamic data objects, they save the programmer the task of dynamic memory management in his or her programs. You should use internal tables whenever you want to process a dataset with a fixed structure within a program. A particularly important use for internal tables is for storing and formatting data from a database table within a program. They are also a good way of including very complicated data structures in an ABAP program.
    Like all elements in the ABAP type concept, internal tables can exist both as data types and as data objects A data type is the abstract description of an internal table, either in a program or centrally in the ABAP Dictionary, that you use to create a concrete data object. The data type is also an attribute of an existing data object.
    Internal Tables as Data Types
    Internal tables and structures are the two structured data types in ABAP. The data type of an internal table is fully specified by its line type, key, and table type.
    Line type
    The line type of an internal table can be any data type. The data type of an internal table is normally a structure. Each component of the structure is a column in the internal table. However, the line type may also be elementary or another internal table.
    Key
    The key identifies table rows. There are two kinds of key for internal tables - the standard key and a user-defined key. You can specify whether the key should be UNIQUE or NON-UNIQUE. Internal tables with a unique key cannot contain duplicate entries. The uniqueness depends on the table access method.
    If a table has a structured line type, its default key consists of all of its non-numerical columns that are not references or themselves internal tables. If a table has an elementary line type, the default key is the entire line. The default key of an internal table whose line type is an internal table, the default key is empty.
    The user-defined key can contain any columns of the internal table that are not references or themselves internal tables. Internal tables with a user-defined key are called key tables. When you define the key, the sequence of the key fields is significant. You should remember this, for example, if you intend to sort the table according to the key.
    Table type
    The table type determines how ABAP will access individual table entries. Internal tables can be divided into three types:
    Standard tables have an internal linear index. From a particular size upwards, the indexes of internal tables are administered as trees. In this case, the index administration overhead increases in logarithmic and not linear relation to the number of lines. The system can access records either by using the table index or the key. The response time for key access is proportional to the number of entries in the table. The key of a standard table is always non-unique. You cannot specify a unique key. This means that standard tables can always be filled very quickly, since the system does not have to check whether there are already existing entries.
    Sorted tables are always saved sorted by the key. They also have an internal index. The system can access records either by using the table index or the key. The response time for key access is logarithmically proportional to the number of table entries, since the system uses a binary search. The key of a sorted table can be either unique or non-unique. When you define the table, you must specify whether the key is to be unique or not. Standard tables and sorted tables are known generically as index tables.
    Hashed tables have no linear index. You can only access a hashed table using its key. The response time is independent of the number of table entries, and is constant, since the system access the table entries using a hash algorithm. The key of a hashed table must be unique. When you define the table, you must specify the key as UNIQUE.
    Generic Internal Tables
    Unlike other local data types in programs, you do not have to specify the data type of an internal table fully. Instead, you can specify a generic construction, that is, the key or key and line type of an internal table data type may remain unspecified. You can use generic internal tables to specify the types of field symbols and the interface parameters of procedures . You cannot use them to declare data objects.
    Internal Tables as Dynamic Data Objects
    Data objects that are defined either with the data type of an internal table, or directly as an internal table, are always fully defined in respect of their line type, key and access method. However, the number of lines is not fixed. Thus internal tables are dynamic data objects, since they can contain any number of lines of a particular type. The only restriction on the number of lines an internal table may contain are the limits of your system installation. The maximum memory that can be occupied by an internal table (including its internal administration) is 2 gigabytes. A more realistic figure is up to 500 megabytes. An additional restriction for hashed tables is that they may not contain more than 2 million entries. The line types of internal tables can be any ABAP data types - elementary, structured, or internal tables. The individual lines of an internal table are called table lines or table entries. Each component of a structured line is called a column in the internal table.
    Choosing a Table Type
    The table type (and particularly the access method) that you will use depends on how the typical internal table operations will be most frequently executed.
    Standard tables
    This is the most appropriate type if you are going to address the individual table entries using the index. Index access is the quickest possible access. You should fill a standard table by appending lines (ABAP APPEND statement), and read, modify and delete entries by specifying the index (INDEX option with the relevant ABAP command). The access time for a standard table increases in a linear relationship with the number of table entries. If you need key access, standard tables are particularly useful if you can fill and process the table in separate steps. For example, you could fill the table by appending entries, and then sort it. If you use the binary search option with key access, the response time is logarithmically proportional to the number of table entries.
    Sorted tables
    This is the most appropriate type if you need a table which is sorted as you fill it. You fill sorted tables using the INSERT statement. Entries are inserted according to the sort sequence defined through the table key. Any illegal entries are recognized as soon as you try to add them to the table. The response time for key access is logarithmically proportional to the number of table entries, since the system always uses a binary search. Sorted tables are particularly useful for partially sequential processing in a LOOP if you specify the beginning of the table key in the WHERE condition.
    Hashed tables
    This is the most appropriate type for any table where the main operation is key access. You cannot access a hashed table using its index. The response time for key access remains constant, regardless of the number of table entries. Like database tables, hashed tables always have a unique key. Hashed tables are useful if you want to construct and use an internal table which resembles a database table or for processing large amounts of data.
    Advanced Topics
    Batch Input: Concepts
    Processing Sessions
    The above figure shows how a batch input session works.A batch input session is a set of one or more calls to transactions along with the data to be processed by the transactions. The system normally executes the transactions in a session non-interactively, allowing rapid entry of bulk data into an R/3 System.
    A session records transactions and data in a special format that can be interpreted by the R/3 System. When the System reads a session, it uses the data in the session to simulate on-line entry of transactions and data. The System can call transactions and enter data using most of the facilities that are available to interactive users.
    For example, the data that a session enters into transaction screens is subject to the same consistency checking as in normal interactive operation. Further, batch input sessions are subject to the user-based authorization checking that is performed by the system.
    Advantages of ABAP over Contemporary languages
    ABAP Objects offers a number of advantages, even if you want to continue using procedural programming. If you want to use new ABAP features, you have to use object-oriented interfaces anyway.
    Sharing Data: With ABAP shared objects, you can aggregate data once at a central location and the different users and programs can then access this data without the need for copying.
    Exception Handling: With the class-based exception concept of ABAP, you can define a special control flow for a specific error situation and provide the user with information about the error.
    Developing Persistency: For permanent storage of data in ABAP, you use relational database tables by means of database-independent Open SQL, which is integrated in ABAP. However, you can also store selected objects transparently or access the integrated database or other databases using proprietary SQL.
    Connectivity and Interoperability: The Exchange Infrastructure and Web services are the means by which developers can implement a service-oriented architecture. With Web services, you can provide and consume services independently of implementation or protocol. Furthermore, you can do so within NetWeaver and in the communication with other systems. With the features of the Exchange Infrastructure, you can enable, manage, and adapt integration scenarios between systems.
    Making Enhancements: With the Enhancement Framework, you can enhance programs, function modules, and global classes without modification as well as replace existing code. The Switch Framework enables you activate only specific development objects or enhancements in a system.
    Considerable Aspects
    It follows a list of aspects to be considered during development. The list of course is not complete.
    Dynpro persistence
    When implementing dynpros one has to care for himself to read out and persist the necessary fields. Recently it happened to me that I forgot to include a field into the UPDATE-clause which is an error not so easy to uncover if you have other problems to be solved in the same package. Here, tool-support or built-in mechanisms would help.
    The developer could help himself out by creating something like a document containing a cookbook or guide in which parts of a dynpro logic one has to care about persistence. With that at hand, it would be quite easy finding those bugs in short time. Maybe a report scanning for the definition of the dynpro fields to be persisted could scan the code automatically, too.
    Memory Cache
    It should be common-sense that avoiding select-statements onto the database helps reducing the server load. For that the programmer either can resort to function modules if available. This maybe is the case for important tables. Or the programmer needs to implement his own logic using internal tables. Here, the standard software package could provide the developer with a tool or a mechanism auto-generating memory cached tables resp. function modules implementing this.
    Sometimes buffering of database tables could be used, if applicable. But that would require an effort in customizing the system and could drain down system performance overall, especially if a table is involved that has a central role.
    Interfaces
    It should be noticed that some function modules available have an incomplete interface. That means, the interface does not include all parameters evaluated by the logic of the function module. For example, global variables from within the function group could be read out, which cannot be influenced by the general caller. Or memory parameters are used internally to feed the logic with further information.
    One workaround here would be copying the relevant parts of the logic to a newly created function module and then adapt it to the own context. This sometimes is possible, maybe if the copied code is not too lengthy and only a few or no calls to other logic is part of it.
    A modification of the SAP code could be considered, if the modification itself is unavoidable (or another solution would be not justifiable by estimated effort to spend on it) and if the location of the modification seems quite safe against future upgrades or hot fixes. The latter is something that could be evaluated by contacting the SAP hotline or working with OSS message (searching thru existing one, perhaps open a new one).

    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.

    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.

    To make things clear, here are two small examples that show how nasty locals and value properties can be to the naive programmer.
    - Open the diagram of the race condition.vi before running it and try to predict what will be the values of the two counters after the third run.
    - Use the Compare Locals Properties and Wires.vi to find out how slow locals and value properties can be (times 1000+).
    This being demonstrated, I must add that I use globals and value properties quite often, because they are often very convenient

  • What is difference between 32 bit and 64 bit sql server memory management

    What is difference between 32 bit and 64 bit sql server memory management
    Thanks
    Shashikala

    This is the basic difference...check if helps:
    A 32-bit CPU running 32-bit software (also known as the x86 platform) is so named because it is based on an architecture that can manipulate values that are up to 32 bits in length. This means that a 32-bit memory pointer can store a value between 0 and
    4,294,967,295 to reference a memory address. This equates to a maximum addressable space of 4GB on 32-bit platforms
    On the other hand 64-bit limit of 18,446,744,073,709,551,616, this number is so large that in memory/storage terminology it equates to 16 exabytes. You don’t come across that term very often, so to help understand the scale, here is the value converted to
    more commonly used measurements: 16 exabytes = 16,777,216 petabytes (16 million PB)➤ 17,179,869,184 terabytes (17 billion TB)➤ 17,592,186,044,416 gigabytes (17 trillion GB)➤
    As you can see, it is significantly larger than the 4GB virtual address space usable in 32-bit systems; it’s so large in fact that any hardware capable of using it all is sadly restricted to the realm of science fiction. Because of this, processor manufacturers
    decided to only implement a 44-bit address bus, which provides a virtual address space on 64-bit systems of 16TB. This was regarded as being more than enough address space for the foreseeable future and logically it’s split into an 8TB range for user mode
    and 8TB for kernel mode. Each 64-bit process running on an x64 platform will be able to address up to 8TB of VAS.

  • Difference between primary eindex and secondary index?

    hi experts
    pls answer me
    difference between primary eindex and secondary index?
    rewads apply.
    thanks.
    naresh.

    hi,
    check this link.
    http://help.sap.com/saphelp_47x200/helpdata/en/cf/21eb2d446011d189700000e8322d00/frameset.htm
    A difference is made between Primary & Secondary indexes to a table. the primary index consists of the key fields of the table and a pointer to the non-keys-fields of the table. The Primary index is generated automatically when a table is created and is created in the datebase as the same times as the table. It is also possible to define further indexes to a table in the ABAP/4 dictionary, which are then referred to as Secondary indexes.
    Always it is not mandatory that an index should have all the key fields of a table. To see the index of a table
    goto SE11->specify table name->click on the indexes... button on the application toolbar.
    Based on your requirement you can you any of those index fields in the where clause of your query. Always its a better practice to use the index fields in the order specified. While selecting the records from a table it is always better to select the fields in the same order as specified in the table.

  • Difference between implicit enhancement and explicit enhancement

    What is the difference between implicit enhancement and explicit enhancement .

    Hi Peters,
    Implicit enhancement option
    Throughout the ABAP system, enhancement options are automatically available at certain pre-defined places. Some of the implicit options are:
    u2022 At the end of all the programs (Includes, Reports, Function pool, Module pool, etc.), after the last statement
    u2022 At the beginning and end of all FORM subroutines
    u2022 At the end of all Function Modules
    u2022 At the end of all visibility areas (public, protected and private) of local class
    To view all the implicit options available in a source code, choose u2018Edit -> Enhancement Operations -> Show Implicit Enhancement Optionsu2019 from the editor.
    Befor that you click on the spiral icon button in the application toolbar
    Explicit enhancement option
    The Implicit enhancement options are provided at specific source code places explicitly by SAP (Note that these enhancement definitions can also be created by partners and customers in their code).
    There are two types of Explicit Enhancement options available. One which can be provided at a specific place - called Enhancement Point, and another which can be used to replace a set of statements u2013 called Enhancement Section. For this, we now have two new ABAP statements, viz.
    u2022 ENHANCEMENT-POINT
    u2022 ENHANCEMENT-SECTION
    When the Enhancement-Section is implemented, only the implementation gets executed and the original code doesnu2019t get executed. This is a new technique, which didnu2019t exist previously in any of the old ways of enhancing, to exclude any standard SAP code from execution. Because of this, there can be only one active implementation of an Enhancement-Section. On the other hand, there can be multiple active implementations of an Enhancement-Point, in which case all the implementations will be executed with no guarantee in the order of execution.

  • Difference between BEx tansport and normal transport

    Dear Experts,
    Could someone please explain the difference between normal transport truck button and the truck with 'BEx' as label.
    Please let me know the context where these will be using
    Kind regards
    Shanthi

    If you press the help button this appears:
    <b>Transporting BEx Objects</b>
      BEx objects (queries and workbooks) are transported differently in BI to
      other objects. When you maintain these objects, you do not get a dialog
      box asking you to create a transport request. Instead, an administrator
      has to generate requests for these objects in the Data Warehousing
      Workbench (function area Transport Connection).
    <b>Standard BEx Transport Requests</b>
      All BEx objects that have been transported already and have therefore
      been assigned to a package, are written to a standard BEx request
      whenever they are changed. This request is set by the administrator. All
      changes are written to this request regardless of the current user.
      When this request is released, the administrator needs to create a new
      BEx request immediately. If there is no request stored as a BEx request,
      you are not able to process queries or workbooks.
    <b>BEx Transport Requests for Single Packages</b>
    In some cases, one request is not big enough for all the BEx objects.
    This can be the case, for example, if you want to transport objects from
    a development system into various different productive systems.
    If this happens, you can create BEx request for each package. The BEx
    objects are distributed among the different requests according to their
    package. The package specifies among other things the transport target
    of an object, and this means that you are able to use this process to
    put BEx objects that you want to transport to different transport
    targets into different requests.
    If you do not create a special request for the package of an object, the
    object is written to the standard BEx transport request.
    Remember to create a new request as soon as one request is released.
    Hope it helps.

  • Difference between Drilldown report and Interactive report

    There is no difference between drill down and interactive report, they are the same.
    With drilldown reporting, SAP provides you with an interactive information system to let you evaluate the data collected in your application. This information system is capable of analyzing all the data according to any of the characteristics that describe the data. You can also use any key figures you wish to categorize your data. You can display a number of objects for a given key figure, or a number of key figures for a given object. In addition, the system lets you carry out any number of variance analyses (such as plan/actual comparisons, fiscal year comparisons, comparisons of different objects, and so on).
    You can produce both simple, data-directed lists (basic reports) and complex, formatted lists in drilldown reporting (form reports).
    Drilldown report provides you with comfortable functions for navigating through your data. For example, you can jump to the next level of detail or the next report object on the same level, hide individual levels and switch between the detail and drilldown lists. It also provides a number of additional functions which let you process lists interactively (sorting, conditions, ranking lists, and so on). SAP Graphics, SAPmail and the Excel List Viewer are also integrated into drilldown reporting.
    The drilldown functions are divided into three groups which differ in the number of functions available. That way each user can choose the functional level most suited for his requirements.
    In addition to the online functions for displaying reports, drilldown reporting also provides functions which let you print reports. A number of formatting functions are available to let you determine the look of your printed reports (page breaks, headers and footers, underscores, and so on).
    The menus and the functions available directly on the drilldown report make it easy to use the information system.
    What is an Interactive Report?
    An interactive report generally works in the following fashion:
    1. Basic list is displayed.
    2. User double clicks on any valid line
        or
        User selects a line and presses as button on the tool bar.
    3. The corresponding event is triggered
    4. Then in the code, the line on which action was done, is read.
    5. Depending on the values in that selected line, a secondary list is displayed.
    6. Steps from 2-5 are repeated till the end.
    From the above explanation, I believe, its clear that, the 20th list, will essentially depend on the "selected line" of 19th list. According to your question, you want to move to 20th list directly, without "a prior list". May I know the exact requirement so that, an appropriate solution can be suggested? 
    Again, your question was, how to move to 20th list directly on pressing of execute button. Its not possible to move to 20th list. You must cross over a basic list, before you can go to a different list level, using the code given by Pavan. 
    What are Drilldown reports?
    The lines of basic list of a drilldown report when clicked, will take the user to the corresponding (standard) object's display.
    For eg: Suppose your report's primary component is purchase requisition, (assume you are printing PR details), and the basic list displays details of many PRs.
    Eg: when clicked on a particular line of the PR basic list, it takes you to std t-code me53 (display of purchase requisition). This is the 'Drill-down' functionality.
    For this, in the at-line selection of your program, as per the above ex: you'll set the parameter ID of PR number BAN (that you can get from Data element) in memory (using set parameter id) and then calling the corresponding transaction (usually skipping initial screen of the std t-code).   
    Likewise, if it's Material Number (Matnr), you'll be displaying MM03 transaction w.r.t. the line's matnr.
    AKSHAT..........

  • DIFFERENCE BETWEEN THE FULL AND BULK-LOGGED RECOVERY MODEL

    DIFFERENCE  BETWEEN THE  FULL AND BULK-LOGGED  RECOVERY MODEL 

    In bulk logged recovery mode certain bulk operations are minimally logged. In FULL recovery mode these are fully logged. These bulk operations are as mentioned below
    1. SELECT INTO
    2. BULK IMport operations including BULK INSERT and BCP
    3. INSERT INTO SELECT command using the OPENROWSET(BULK) function
    4. Partial updates to columns having large value data type
    5. Using WRITE clause in UPDATE statements
    6. Index operations e.g CREATE INDEX, ALTER INDEX REBUILD , DROP INDEX
    In Bulk Logged Recovery Mode when you execute these operations SQL Server only logs the fact that these operation occured and information about space allocation. The actual change in the data is maintained in the BCM (Bulk
    Changed Map)
    Since the actual changes are not recorded in the log file, the log file size in the reletively less in size but this tradeoff comes with the price of increased backup time. This is so because during the log backup its not just the log being backup, but also
    the extents that are marked by the Bulk Changed Map as changed.

  • List of differences between PSE 40 and PSE30

    A lot of users are asking what are the differences between PSE 30 and PSE 40.
    This Thread provides information on this subject. First, you will find information copied from the section "New Features" of the useful "Adobe Photoshop Elements 4.0 User Guide". Then later on, you might find additional information on the same subject provided by users of PSE.
    --- Start of copy of information in the PSE 4.0 User Guide ----
    1 What's new in PSE 4.0
    1.1 Editing and selection
    1.1.1 Magic Selection Brush tool
    Easily and accurately select portions of your photos using this new tool in either Standard Edit and Quick Fix. Simply scribble or place dots on the object you want to select -no need to precisely outline the object- and Adobe Photoshop Elements selects the object for you. You can add to or subtract from the selection by using additional tools in the options bar. (See User Guide "To use the Magic Selection Brush tool" on page 193.)
    1.1.2 Magic Extractor.
    Easily select an object in a photo and extract it from its background. Just scribble or place dots on
    the object you want to extract; then scribble or place dots on the background, and Photoshop Elements separates the object from its background. This tool is perfect for creating composites or scrapbook images. (See User Guide "To use the Magic Extractor" on page 194.)
    1.1.3 Skin tone adjustment
    Click an area of skin and watch the tonal balance of all colors in the photo improve. If you
    want, you can also manually adjust the color by using color sliders. (See User Guide "To adjust the color of skin tone" on page 224.)
    1.1.4 Red eye removal
    Automatically remove red eye during import, or select one or more files and easily remove red eye
    in either the Organizer or the Editor. (See User Guide "To remove red eye" on page 249.)
    1.1.5 Defringe
    Automatically remove the colored specs or halo around the edges of a selection. (See User Guide "To defringe a Selection" on page 200.)
    1.1.6 Straighten tool
    Straighten and crop crooked photos by drawing a horizontal or vertical line in the image. Photoshop
    Elements aligns the photo to that line. (See User Guide "To straighten an image" on page 243.)
    1.1.7 WYSIWYG font menu
    What you see is what you get -see what each font looks like from within the font menu. (See
    User Guide "To choose a font family and style" on page 332.)
    1.2 Sharing and printing
    1.2.1 One-click printing (US, Canada, Japan only)
    Order prints and professional hardbound photo books directly from Photoshop Elements simply by dragging the items to the Order Prints palette. (See User Guide "To use the Order Prints palette (US, Canada, Japan only)" on page 401.)
    1.2.2 Slide shows on TV
    If you have Windows¨ XP Media Center 2005 installed, you can view your Photoshop Elements
    slide shows on your TV and navigate using your TV remote control. (See User Guide "To output a slide show" on page 354.)
    1.3 Tagging and organizing
    1.3.1 Face tagging
    Select a group of photos and let Photoshop Elements isolate and display all the faces so that you can
    quickly tag them. The Find Faces dialog box displays thumbnails of each face until you tag it. (See User Guide "To automatically find faces for tagging" on page 101.)
    1.3.2 Search by metadata
    Search for a variety of metadata criteria, such as file name, file type, shutter speed, camera
    model, date, and tags. You can search on multiple criteria at once. (See User Guide "To find photos by details (metadata)" on page 89.)
    1.3.3 PDF support
    Manage and tag PDF files in the Organizer. PDF files remain intact as one file that you can tag. Open

  • Difference between Smart Forms and Adobe Form

    Hi all,
    What are disadvantages of Smart form in SAP ,
    What is difference between Smart Forms and Adobe interactive Form.
    I heard from someone that in future Adobe interactive Form will repalce smart forms. Is it true or not
    Best Regards
    Srikanth

    Hi,
    Companies depend on formal documents that reflect their corporate identities and contain critical business information from live systems. SAP and Adobe partnered for automating and streamlining forms-based communication to support customers who create reusable forms for their business processes.
    SAP Interactive Forms by Adobe will be used more and more as a way of simplifying and automating manual processes.
    There are various advantages of Adobe forms.
    SAP Interactive Forms by Adobe provides all the features and functions you need to create form-based output, such as order confirmations, invoices, or pay slips. You can either print such documents or send them by email or FAX.
    <b>Online Interactive Forms</b>
    A user logs on to the company intranet to fill in a form required by the HR department (for example, a Non-Disclosure Agreement to be signed by a new employee). The form is displayed in the browser.
    As the user is logged on in the background to the company's HR system, his master data is displayed in the form. The user enters the required information in the fillable fields of the interactive form, and sends the data back to the system by pushing a button. The system extracts the data from the form and saves it in the database.
    <b>Offline Interactive Forms</b>
    The purchasing department of a company creates a bid in its Enterprise Resource Planning (ERP) system and selects the potential vendors. Based upon this data, the system automatically creates interactive bidding forms with specific vendor information, such as the address or contact person.
    The forms are transmitted to the vendors by email. The vendors can fill out the forms offline (without being connected to the system that created the forms) and transmit them back to the company. The company then processes the forms automatically, and the data provided by the vendors is written to the ERP system. The purchasing department uses the data to evaluate the quotation and then issues an order.
    <b>With the integration of Adobe PDF technology into its solutions, SAP will be able to further extend its offerings of end-to-end business solutions by:</b>
    Providing for the first time the capabilities of Adobe's interactive PDF-based forms.
    Integrating PDF documents into business processes that are driven by SAP applications.
    Automating the process of moving XML data from SAP applications into interactive forms and vice versa.
    Reducing time to design, manage, and maintain extended forms-based processes through easy-to-use forms design and deployment tools.
    Offering its customers enhanced printing capabilities, in particular for interactive Web applications.
    The focus of new forms technology from SAP is interactive PDF-based forms that can be created in SAP systems as a result of the <b>integration of Adobe technology with Web Dynpro and the SAP NetWeaver Developer Studio.</b> This integration means that adobe is the future technology.
    Regards,
    Kate
