Can we use Union in ABAP???

Can we use Union in ABAP???
I have scenario like,
in an internal table i have entrie like this,
comp code     field1       field2       field3        field4       field5
0A1                   ABC        BCD          00             00              00
0A1                    00            00            CDE           00              00      
0A1                    00            00            00              EFG           IJK
but i need a single entry like this,
comp code     field1       field2       field3        field4       field5
0A1               ABC        BCD         CDE           EFG             IJK
how to do this????

You cannot use SELECT on internal tables so the question of UNION does not arise. Also, you cannot use UNION in ABAP. You need to code it to get the desired output
Move the first line of your internal table to a new int table i_ftab.
  DATA: num TYPE char1.
  num = 2.
  DO.
    READ TABLE i_tab -> initial internal table
      INTO wa_tab INDEX num.
    IF sy-subrc NE 0.
      EXIT.
    ENDIF.
    IF wa_tab-code NE '000'.
      MODIFY i_ftab INDEX 1 FROM wa_tab TRANSPORTING code.
    ELSEIF wa_tab-field1 NE '000'.
      MODIFY i_ftab INDEX 1 FROM wa_tab TRANSPORTING field1.
    ENDIF.
    num = num + 1.
  ENDDO.

  • How can I use the WebDynpro tutorial  template in APAB workbench?

    Hi,
    I have downloaded the tutorial template zip file from sdn (https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webas/webdynpro/tutorial on creating trees in web dynpro - 12.htm), but I don't know how to use it in ABAP workbench.
    Is that only for Java environment and can be used in Eclipse?
    If not, How can it be used in APAB workbench?
    Thank you.

    Hi,
    Its a template used in NDS(NetWeaver Developer Studio),in Webdynpro perspective.
    what do u mean by how can i use it in ABAP workbench?
    Sorry u cant use tat existing template.
    if u need the same feature u have to develop ur own...:)

  • Can I use logical databases in a WebDynpro ABAP program?

    can I use logical databases in a WebDynpro ABAP program?
    I need to build a WDA screen that is similar to the SAPDBPNP selection screen (user can find the personnel number based on several criteria, such as last_name/first_name of the employee).  So it seems that the existing logical databases have already many nice features already built (like the selection screens, the logic behind the screens etc). So I was wondering if/how I can use them in my WDA application.

    Hello, Tiberiu.
    You cannot use LDB directly within your WDA programa. BUT, you can fetch results from this LDB by using FM LDB_PROCESS. This function module can be called anytime from any kind of ABAP program. But you will still have to create the screen, as it only processes data, not screens.
    Regards,
    Andre
    PS: Pls reward points if it helps.

    Hi
    Please let me also know the solution to this. I am a beginner to WebDynpro  and want to know if I can make use of LDB's as we do in our normal HR programming do develop a WDA in HR.

  • How can we use TABLE CONTROL in BDC and WORK FLOW of ABAP.

    how can we use TABLE CONTROL in BDC and WORK FLOW of ABAP.?
    please explain the important questions.

    How to deal with table control / step loop in BDC
    Steploop and table contol is inevitable in certain transactions. When we run BDC for such transactions, we will face the situation: how many visible lines of steploop/tablecontrol are on the screen? Although we can always find certain method to deal with it, such as function code 'NP', 'POPO', considering some extreme situation: there is only one line visible one the screen, our BDC program should display an error message. (See transaction 'ME21', we you resize your screen to let only one row visible, you can not enter mutiple lines on this screen even you use 'NP')
    Now with the help of Poonam on sapfans.com developement forum, I find a method with which we can determine the number of visible lines on Transaction Screen from our Calling BDC program. Maybe it is useless to you, but I think it will give your some idea.
    Demo ABAP code has two purposes:
    1. how to determine number of visible lines and how to calculte page number;
    (the 'calpage' routine has been modify to meet general purpose usage)
    2. using field symbol in BDC program, please pay special attention to the difference in Static ASSIGN and Dynamic ASSIGN.
    Now I begin to describe the step to implement my method:
    (I use transaction 'ME21', screen 121 for sample,
    the method using is Call Transation Using..)
    Step1: go to screen painter to display the screen 121, then we can count the fixed line on this screen, there is 7 lines above the steploop and 2 lines below the steploop, so there are total 9 fixed lines on this screen. This means except these 9 lines, all the other line is for step loop. Then have a look at steploop itselp, one entry of it will occupy two lines.
    (Be careful, for table control, the head and the bottom scroll bar will possess another two fixed lines, and there is a maximum number for table line)
    Now we have : FixedLine = 9
                  LoopLine  = 2(for table control, LoopLine is always equal to 1)
    Step2: go to transaction itself(ME21) to see how it roll page, in ME21, the first line of new page is always occupied by the last line of last page, so it begin with index '02', but in some other case, fisrt line is empty and ready for input.
    Now we have: FirstLine = 0
              or FirstLine = 1 ( in our case, FirstLine is 1 because the first line of new page is fulfilled)
    Step3: write a subroutine calcalculating number of pages
    (here, the name of actual parameter is the same as formal parameter)
    global data:    FixedLine type i, " number of fixed line on a certain screen
                    LoopLine  type i, " the number of lines occupied by one steploop item
                    FirstLine type i, " possbile value 0 or 1, 0 stand for the first line of new                                                               " scrolling screen is empty, otherwise is 1
                    Dataline  type i, " number of items you will use in BDC, using DESCRIBE to get
                    pageno    type i, " you need to scroll screen how many times.
                    line      type i, " number of lines appears on the screen.
                    index(2)  type N, " the screen index for certain item
                    begin     type i, " from parameter of loop
                    end       type i. " to parameter of loop
    *in code sample, the DataTable-linindex stands for the table index number of this line
    form calpage using FixedLine type i (see step 1)
                       LoopLine  type i (see step 1)
                       FirstLine type i (see step 2)
                       DataLine  type i ( this is the item number you will enter in transaction)
              changing pageno    type i (return the number of page, depends on run-time visible                                                                             line in table control/ Step Loop)
              changing line      type i.(visible lines one the screen)
    data: midd type i,
          vline type i, "visible lines
    if DataLine eq 0.
       Message eXXX.
    endif.
    vline = ( sy-srows - FixedLine ) div LoopLine.
    *for table control, you should compare vline with maximum line of
    *table control, then take the small one that is min(vline, maximum)
    *here only illustrate step loop
    if FirstLine eq 0.
            pageno = DataLine div vline.
            if pageno eq 0.
               pageno = pageno + 1.
            endif.

  • Can we use overload and overwrite concept in OO-abap

    ENDCLASS. "zl_lcl_vehicle
    Overloading means changing signature as well as implementation of a method.
    Overriding is changing only implementation of method with signature unchanged.
    From ABAP perspective, only the CONSTRUCTOR method can be overloaded in a subclass i.e both the signature and implementation can be adapted in subclass.
    Any other method can't be overloaded. It can only be redefined/overridden i.e implementation changed with signature unchanged.
    In ABAP  there is something called a redefinition.
    When you inherit a class from a super class, you can redifne a method. You cannot chnage the signature( Interface) of the method. It will remain the same as that of the super class.You must redefine a method in the same visibility section in which it appears in the superclass.
    Eg.
    CLASS C_SUPER_CLASS DEFINITION .
    PUBLIC SECTION.
    METHODS: DRIVE ,
    STOP.
    PROTECTED SECTION.
    DATA SPEED TYPE I.
    ENDCLASS.
    CLASS C_SUPER_CLASS IMPLEMENTATION.
    METHOD DRIVE.
    SPEED = 0.
    WRITE: / 'Bike speed =', SPEED.
    ENDMETHOD.
    ENDCLASS.
    CLASS C_SUB_CLASS DEFINITION INHERITING FROM C_SUPER_CLASS.
    PUBLIC SECTION.
    METHODS DRIVE REDEFINITION.
    ENDCLASS
    CLASS C_SUB_CLASS IMPLEMENTATION.
    METHOD DRIVE.
    SPEED = SPEED + 10.
    WRITE: / 'Bicycle speed =', SPEED.
    ENDMETHOD.
    ENDCLASS.

  • Is ABAP expression FORM - PERFORM can be used in SAP BI 7.0 transformation

    Hello
    Is ABAP expression FORM - PERFORM can be used in SAP BI 7.0 transformations or method odf class is a recommended approach?
    Thanks

    SAP BI 7.x Transformations use OO ABAP where the logic that you enter into the tranformational routines (Start Routine, Characteristic Routines and End Routine) are inside METHODS. PERFORM and FORM are procedural-based ABAP and cannot be used in METHODS.
    CLASS-METHOD and Function Modules are your best bets for processing outside of the transformational routine. As for performance, we use both and haven't found any signicant difference between the two (our custom Function Modules usually perform only slight better than our custom METHODS).

  • How can we use business object (e.g. crystal report ) in webdynpro abap

    Hi All,
    We all know that business object has been part of sap products.
    But even though in SAP, I really don't know much about business object.
    and how can we use the great function of BO and integrate into our development to make
    user have much better function and user experience.
    Do we have some learning material of BO?
    Could someone share some material here?
    Thanks and Regards
    Aaron.

    One of the main ways that you can integrate some Business Objects content with WDA is via FlashIslands.  If you are on 7.01 or higher, you have the option to use FlashIslands UI element.  There are many tutorials on FlashIslands available on SDN. FlashIslands work well with Xcelsius content, since the output of Xcelsius is a Flex component.  It is pretty easy to set the Xcelsius interface to External Connection and then write a wrapper Flex Component around the generated output, so that it can be used in the FlashIslands interface.
    For Crystal Reports integration you will need NetWeaver 7.02 (comming early next year).  We have integrated Crystal Reports as an output option in the Web Dynpro ABAP ALV and the Classic Dynpro ALV.  You don't need to do any development to enable this.  You can use two different SAP delivered Crystal Reports templates for the ALV output, or create and add your own templates.
    Some of ther BOBJ integration is still in prototype and demo phase within SAP.  For instance we have a data interface to send data to Explorer onDemand from any ABAP application. We have a prototype FlashIsland for WebI to run in place within Web Dynpro ABAP.  Over future enhancement packages you will see increased integration opportunties with the BOBJ capabilites.

  • Can i use any OWB mapping operator when i generate ABAP

    it seems like in OWB mappings, if i have a SAP table as data source and i want to perform some operations (eg. JOIN, input parameters, expressions) i am limited to generating PLSQL code.
    all i can get if i want ABAP generated code is a simple table (all records) column to column mappings ! is this true or am i missing some important steps ?
    eg. how can i specify a date as input parameter to be used as a filter value on a SAP table before storing the results in a staging table ? keep in mind that i am expecting the extraction code to be in ABAP ...

    You need to specify the join condition to generate ABAP code. Start by specfying a foreign key based on the join condition. In table 1, create a unique key. In table 2, create a foreign key based on the unique key of table 1.
    There should not be any problem with the filter condition generating ABAP code. If you would like more specific assistance, log a technical assistance request (TAR) on MetaLink and Support can review your map.

  • Can you use ABAP for B1 Development

    Hi
    I have been lookng for answer for the following 2 questons.
    1.  Is is it possible to use ABAP for B1 Development to create Add-ons.
    2. In the standard forms/reports there is no figure to words conversion. Please high light on how to do this.
    Ramesh Shankaran

    Short answer: no you cannot.
    Longer answer: B1 gives you access to its objects and GUI
    with COM-based libraries. Any language that supports COM
    can be used, included VB, VB.NET, C#, C and C++. A wrapper
    for Java is also provided to access B1 objects.

  • Can I use Tcode to start a webdynpro for abap or for JAVA?

    I noticed some page program can be started by tcode for administrion. I am not sure whether it is webdynpro or BSP. But can I use tcode to start webdynpro? How to do it?

    Hi Yichao,
    To Create a Transaction code for a Web Dynpro application, use Transaction SE93 (Transaction Maintenance).
    1.       On the dialog screen, enter the transaction code (up to 20 characters) then click on Create button.
    2.       A dialog pop up screen appears, enter meaningful description of the transaction in the Short Text field.
    3.       Choose the option Transaction with parameters (Parameter transaction).
    4.       Choose Continue. The Create Parameter Transaction screen appears.
    5.       In the Transaction field, enter WDYID and select the checkbox Skip initial screen. There is no need to make changes in the Classification group box.
    6.       Add the necessary entries to the Default Values table by using the F4 help. The values are automatically available after you enter WDYID in the Transaction field.
    Try going through this link for a better picture about how to achieve this.
    saptechnical . com / Tutorials / WebDynproABAP / TransactionCode / Create.htm
    You would have to remove the unnecessary spaces in the URL before you can see the actual working one. It wasn't allowing me to paste that link in here so had to do it this way...

  • Can I use classes and methods for a maintenance view events?

    Hello experts,
    Instead of perform/form, can I instead use classes and methods, etc for a given maintenance view event, lets say for example I want to use event '01' which is before saving records in the database. Help would be greatly appreciated. Thanks a lot guys!

    Hi viraylab,
    1. The architecture provided by maintenance view
       for using EVENTS and our own code inside it -
       It is provided using FORM/PERFORM
       concept only.
    2. At this stage,we cannot use classes.
    3. However, inside the FORM routine,
       we can write what ever we want.
       We can aswell use any abap code, including
       classes and methods.
      (But this classes and methods won't have any
       effect on the EVENT provided by maintenance view)
    regards,
    amit m.
