ALV OO TREE in a function module

Hi everybody,
Probably somebody can help me with this. I am trying to create an ALV OO TREE and I am following one of the examples that is in the system (BCALV_TREE_SIMPLE_DEMO) because it is more or less what I need. The problem I have is that I need to create a function module that contains this ALV_TREE so the import of this FM would be the table with the info, and as I saw I need to use PBO and PAI to create it with objects because if not it doesn't work, it doesn't show anything. I just create a report to test it, but now I need to create the FM, does anybody knows how to do it without this PBO and PAI or just with it but using the function module to create the ALV view?
Thanks very much

  • How to do ALV Popup in a new Function module

    Hi experts,
    This is the Client Requirement.
    " Flow Diagram/Pseudo Code:
    Attach a data flow diagram. Write brief pseudo code in plain English.  Be sure to include all access data plans.
    -     FM interface:
    -     Import: company code/ vendor#.
    -     Export: default_line,  type y4ap_t11
    -     Exception: NO_DATA or CANCELED
    In the FM code, past current z_venddefault code, except for write statements. After internal table is generated, show it in ALV popup. On ALV, add a OK/Cancel button. On OK, ensure that one line is selected (otherwise throw warning), and then fill export structure with that line’s G/L account, cost Center, and internal order# fields. Then close the ALV and end FM. For Cancel, just close the ALV end the FM.
    For an example of how to build such popup ALVs, take a look at FM Y4AP_SELECT_APPROVER.
    Unit Test Plan:
    Just use co.code 3000/vend# 1000 to test this FM."

    plz help me.
    thanks
    sudheer

    Hi,
    Hope the following helps..
    1)
    LOOP AT IT_OUTPUT.
    Call the function module to get the tracking number and store the output in the
    variable V_TRACKINGNO.
      IT_OUTPUT-TRACKING_NO = V_TRACKINGNO.
      MODIFY IT_OUTPUT TRANSPORTING TRACKING_NO.
    ENDLOOP.
    2) Date conversion
    DATA: V_CHAR(10) VALUE '2006.11.17'.
    DATA: V_DATE       TYPE SYDATUM.
    CONCATENATE V_CHAR(4) V_CHAR5(2) V_CHAR8(2) INTO V_DATE.
    WRITE: V_DATE TO V_CHAR MM/DD/YYYY.
    WRITE: / 'MM/DD/YYY Format - ',  V_CHAR.

  • Alv query regarding function modules

    hi all,
    what is difference between
    Reuse_alv_list_display & Reuse_alv_grid_display?
    thanks & regards
    sanjeev

    hi,
    1. For all practical purposes, they are the same.
    2. Some differences:
    a) from abap coding point of view,
    alv list is done with Function modules,
    alv gris can also be done with FM,
    but can also be done using OO concepts.
    b) Alv grid (using oo concept) requires
    designing the screen layout .
    Hence, in one screen, we can show more
    then one alv grid
    (we cannot show more than
    one alv list on one screen)
    c) ALV grid uses ActiveX controls
    present on the Presentation Server.
    Hence, it consumes More Memory
    on the presentation server.
    d) ALV LIST is Display Only.
    Whereas
    ALV Grid Can Be made EDITABLE for entry purpose.
    e) In alv grid, these options are possible,
    but not in alv list.
    without horizontal lines
    without vertical lines
    without cell merging during sorts
    display total lines above the entries
    ALV LIST Can be coded using only FMs
    ALV GRID Can be coded using FMs and object oriented concepts
    ALV LIST Can be displayed hieraicharlly
    ALV GRID cannot be displayed hierarichally
    I hope it helps.

  • How to call the Report program into Function module

    Hi Experts,
    Actually I want to create the DataSource. But I have only the ALV report program. I need to create function module but I don’t know how to call the ALV report program using in function module  
    So could you please any one send the Document or step by step method?
    Advance Thanks,
    Sathis

    If the report is just based out of a table than create a Generic Extractor using View.
    If its an InfoSet query than create a Generic Extractor on that InfoSet.
    If its an ABAP report than create a Generic Extractor using FM

  • Function module used for formatting alv

    hi gurus,
    which function module is uesd to format alv?

    Hi
    see the following
    ABAP List Viewer
    The common features of report are column alignment, sorting, filtering, subtotals, totals etc. To implement these, a lot of coding and logic is to be put. To avoid that we can use a concept called ABAP List Viewer (ALV).
    This helps us to implement all the features mentioned very effectively.
    Using ALV, We can have three types of reports:
    1. Simple Report
    2. Block Report
    3. Hierarchical Sequential Report
    There are some function modules which will enable to produce the above reports without much effort.
    All the definitions of internal tables, structures and constants are declared in a type-pool called SLIS.
    1. SIMPLE REPORT.
    The important function modules are
    a. Reuse_alv_list_display
    b. Reuse_alv_fieldcatalog_merge
    c. Reuse_alv_events_get
    d. Reuse_alv_commentary_write
    e. Reuse_alv_grid_display
    A. REUSE_ALV_LIST_DISPLAY : This is the function module which prints the data.
    The important parameters are :
    I. Export :
    i. I_callback_program : report id
    ii. I_callback_pf_status_set : routine where a user can set his own pf status or change the functionality of the existing pf status
    iii. I_callback_user_command : routine where the function codes are handled
    iv. I_structure name : name of the dictionary table
    v. Is_layout : structure to set the layout of the report
    vi. It_fieldcat : internal table with the list of all fields and their attributes which are to be printed (this table can be populated automatically by the function module REUSE_ALV_FIELDCATALOG_MERGE
    vii. It_events : internal table with a list of all possible events of ALV and their corresponding form names.
    II. Tables :
    i. t_outtab : internal table with the data to be output
    B. REUSE_ALV_FIELDCATALOG_MERGE : This function module is used to populate a fieldcatalog which is essential to display the data in ALV. If the output data is from a single dictionary table and all the columns are selected, then we need not exclusively create the field catalog. Its enough to mention the table name as a parameter(I_structure name) in the REUSE_ALV_LIST_DISPLAY. But in other cases we need to create it.
    The Important Parameters are :
    I. Export :
    i. I_program_name : report id
    ii. I_internal_tabname : the internal output table
    iii. I_inclname : include or the report name where all the dynamic forms are handled.
    II Changing
    ct_fieldcat : an internal table with the type SLIS_T_FIELDCAT_ALV which is
    declared in the type pool SLIS.
    C. REUSE_ALV_EVENTS_GET : Returns table of possible events for a list type
    Parameters :
    I. Import :
    Et_Events : The event table is returned with all possible CALLBACK events
    for the specified list type (column 'NAME'). For events to be processed by Callback, their 'FORM' field must be filled. If the field is initialized, the event is ignored. The entry can be read from the event table, the field 'FORM' filled and the entry modified using constants from the type pool SALV.
    II. Export :
    I_List_type :
    0 = simple list REUSE_ALV_LIST_DISPLAY
    1 = hierarchcal-sequential list REUSE_ALV_HIERSEQ_LIST_DISPLAY
    2 = simple block list REUSE_ALV_BLOCK_LIST_APPEND
    3 = hierarchical-sequential block list
    REUSE_ALV_BLOCK_LIST_HS_APPEND
    D. REUSE_ALV_COMMENTARY_WRITE : This is used in the Top-of-page event to print the headings and other comments for the list.
    Parameters :
    I. it_list_commentary : internal table with the headings of the type slis_t_listheader.
    This internal table has three fields :
    Typ : ‘H’ – header, ‘S’ – selection , ‘A’ - action
    Key : only when typ is ‘S’.
    Info : the text to be printed
    E. REUSE_ALV_GRID_DISPLAY : A new function in 4.6 version, to display the results in grid rather than as a preview.
    Parameters : same as reuse_alv_list_display
    This is an example for simple list.
    2. BLOCK REPORT
    This is used to have multiple lists continuously.
    The important functions used in this report are:
    A. REUSE_ALV_BLOCK_LIST_INIT
    B. REUSE_ALV_BLOCK_LIST_APPEND
    C. REUSE_ALV_BLOCK_LIST_HS_APPEND
    D. REUSE_ALV_BLOCK_LIST_DISPLAY
    A. REUSE_ALV_BLOCK_LIST_INIT
    Parameters:
    I. I_CALLBACK_PROGRAM
    II. I_CALLBACK_PF_STATUS_SET
    III. I_CALLBACK_USER_COMMAND
    This function module is used to set the default gui status etc.
    B. REUSE_ALV_BLOCK_LIST_APPEND
    Parameters :
    Export :
    I. is_layout : layout settings for block
    II. it_fieldcat : field catalog
    III. i_tabname : internal table name with output data
    IV. it_events : internal table with all possible events
    Tables :
    i. t_outtab : internal table with output data.
    This function module adds the data to the block.
    Repeat this function for all the different blocks to be displayed one after the other.
    C. REUSE_ALV_BLOCK_LIST_HS_APPEND
    This function module is used for hierarchical sequential blocks.
    D. REUSE_ALV_BLOCK_LIST_DISPLAY
    Parameters : All the parameters are optional.
    This function module display the list with data appended by the above function.
    Here the functions REUSE_ALV_FIELDCATALOG_MERGE, REUSE_ALV_EVENTS_GET, REUSE_ALV_COMMENTARY_WRITE can be used.
    3. Hierarchical reports :
    Hierarchical sequential list output.
    The function module is
    A. REUSE_ALV_HIERSEQ_LIST_DISPLAY
    Parameters:
    I. Export:
    i. I_CALLBACK_PROGRAM
    ii. I_CALLBACK_PF_STATUS_SET
    iii. I_CALLBACK_USER_COMMAND
    iv. IS_LAYOUT
    v. IT_FIELDCAT
    vi. IT_EVENTS
    vii. i_tabname_header : Name of the internal table in the program containing the
    output data of the highest hierarchy level.
    viii. i_tabname_item : Name of the internal table in the program containing the
    output data of the lowest hierarchy level.
    ix. is_keyinfo : This structure contains the header and item table field
    names which link the two tables (shared key).
    II. Tables
    i. t_outtab_header : Header table with data to be output
    ii. t_outtab_item : Name of the internal table in the program containing the
    output data of the lowest hierarchy level.
    slis_t_fieldcat_alv : This internal table contains the field attributes. This internal table can be populated automatically by using ‘REUSE_ALV_FIELDCATALOG_MERGE’.
    Important Attributes :
    A. col_pos : position of the column
    B. fieldname : internal fieldname
    C. tabname : internal table name
    D. ref_fieldname : fieldname (dictionary)

    hi,
    in alv's using fuction modules how to add pushbuttons in application tool bar?

    Hi Ganapathi,
    Check out the list of Function Modules
    ABAP_DOCU_DOWNLOAD     Download ABAP documentation in HTML format.
    APPL_LOG_DELETE     With this function module you delete logs in the database according to specified selection conditions
    APPL_LOG_DISPLAY     With this function module you can analyze logs in the database.
    APPL_LOG_DISPLAY_INTERN     With this function module you can analyze logs in local memory, e.g. when you have only collected log records at runtime and do not want to write to the database.
    APPL_LOG_INIT     This function module checks whether the specified object or sub-object exists and deletes all existing associated data in local memory.
    APPL_LOG_READ_DB     With this function module you read the log data in the database for an object or sub-object according to specified selection conditions.
    APPL_LOG_READ_INTERN     With this function module you read all log data whose log class has at least the specified value, from local memory, for the specified object or sub-object.
    APPL_LOG_SET_OBJECT     With this function module, you create a new object or sub-object for writing in local memory. With a flag you can control whether the APPL_LOG_WRITE_... messages are written in local memory or are output on the screen.
    APPL_LOG_WRITE_DB     With this function module you write all data for the specified object or sub-object in local memory to the database. If the log for the object or sub-object in question is new, the log number is returned to the calling program.
    APPL_LOG_WRITE_HEADER     With this function module, you write the log header data in local memory.
    APPL_LOG_WRITE_LOG_PARAMETERS     With this function module, you write the name of the log parameters and the associated values for the specified object or sub-object in local memory. If this function module is called repeatedly for the same object or sub-object, the existing parameters are updated accordingly. If you do not specify an object or sub-object with the call, the most recently used is assumed.
    APPL_LOG_WRITE_MESSAGE_PARAMS     With this function module you write a single message, with parameters, in local memory. Otherwise the function module works like APPL_LOG_WRITE_SINGLE_MESSAGE.
    APPL_LOG_WRITE_MESSAGES     With this function module you write one or more messages, without parameters, in local memory.
    APPL_LOG_WRITE_SINGLE_MESSAGE     With this function module you write a single message, without parameters, in local memory. If no header entry has yet been written for the object or sub-object, it is created. If you do not specify an object or sub-object with the call, the most recently used is assumed.

          value like kna1-begru,
        end of t_values,
        t_return like ddshretval occurs 0 with header line.
      t_values = 'PAR*'.
      append t_values.
      t_values = 'UGG'.
      append t_values.
      call function 'F4IF_INT_TABLE_VALUE_REQUEST'
           exporting
                retfield        = 'BEGRU'
                value_org       = 'S'
           tables
                value_tab       = t_values
                return_tab      = t_return
           exceptions
                parameter_error = 1
                no_values_found = 2
                others          = 3.
      if sy-subrc = 0.

        if o_begru-low = 'PAR*'.
          o_begru-option = 'CP'.
        else.
          o_begru-option = 'EQ'.
        endif.
        o_begru-sign = 'I'.
        append o_begru to s_begru.
      else.
        o_begru = i_begru.
      endif.
    F4IF_SHLP_EXIT_EXAMPLE     documents the different reasons to use a search help exit, and shows how it is done.
    F4IP_INT_TABLE_VALUE_REQUEST     This function does not exist in 4.6 and above. Use F4IF_INT_TABLE_VALUE_REQUEST instead.
    FILENAME_GET     popup to get a filename from a user, returns blank filename if user selects cancel
    FORMAT_MESSAGE     Takes a message id and number, and puts it into a variable. Works better than WRITE_MESSAGE, since some messages use $ as a place holder, and WRITE_MESSAGE does not accommodate that, it only replaces the ampersands (&) in the message.
    FTP_COMMAND     Execute a command on the FTP server
    FTP_CONNECT     Open a connection (and log in) to an FTP server
    FTP_DISCONNECT     Close the connection (and log off) the FTP server
    FU CSAP_MAT_BOM_READ     You can use this function module to display simple material BOMs. You cannot display BOM groups (for example, all variants of a variant BOM). as in transaction CS03. Current restrictions: You cannot display long texts. You cannot display sub-items. You cannot display classification data of BOM items for batches. You can only display one alternative or variant. You cannot enter an alternative for module CSAP_MAT_BOM_READ, so you always see alternative 01. The following example came from a posting on the SAP-R3-L mailing list.
    Example:
    data: begin of tstk2 occurs 0.
              include structure stko_api02.
    data: end of tstk2.
    data: begin of tstp2 occurs 0.
              include structure stpo_api02.
    data: end of tstp2.
    data: begin of tdep_data occurs 0.
             include structure csdep_data.
    data: end of tdep_data.
    data: begin of tdep_descr occurs 0.
             include structure csdep_descr.
    data: end of tdep_descr.
    data: begin of tdep_source occurs 0.
             include structure csdep_source.
    data: end of tdep_source.
    data: begin of tdep_order occurs 0.
             include structure csdep_order.
    data: end of tdep_order.
    data: begin of tdep_doc occurs 0.
             include structure csdep_doc.
    data: end of tdep_doc.
    data: flg_warning like capiflag-flwarning.
       call function 'CSAP_MAT_BOM_READ'
            exporting
                 material   = 'MAT100'
                 plant      = '0001'
                 bom_usage  = '1'
                 valid_from = '20.12.1996'
               valid_to
            importing
                 fl_warning = flg_warning
            tables
                 t_stko       = tstk2
                 t_stpo       = tstp2
                 t_dep_data   = tdep_data
                 t_dep_descr  = tdep_descr
                 t_dep_source = tdep_source
                 t_dep_order  = tdep_order
                 t_dep_doc    = tdep_doc
            exceptions
                 error      = 1.
    Function Group GRAP is now obsolete.     SAP recommends using functions in function group SFES instead. Below is an overview of the changes.
    G_SET_GET_ALL_VALUES     Fetch values from a set.
    GET_CURRENT_YEAR     Get the current fiscal year.
    Example:

      IMPORTING
        CURRM         = w_currm    " Current Fiscal Month
        CURRY         = w_curry    " Current Fiscal Year
        PREVM         = w_prevm    " Previous Fiscal Month
        PREVY         = w_prevy.   " Previous Fiscal Year
    GET_GLOBAL_SYMBOLS     Returns a list of all tables, select options, texts, etc for a program. Even includes the text definitions for the selection screen

    HELP_VALUES_GET_WITH_TABLE     Show a list of possible values for F4 popup help on selection screens. This function module pops up a screen that is just like all the other F4 helps, so it looks like the rest of the SAP system. Very useful for providing dropdowns on fields that do not have them predefined.
    Example:
    tables: t001w.
    DATA: lc_werks      LIKE t001w-werks,
          ltab_fields LIKE help_value OCCURS 0 with header line,
          BEGIN OF ltab_values OCCURS 0,
            feld(40) TYPE c,
          END OF ltab_values.
    *-- Set up fields to retrieve data

      ltab_fields-fieldname  = 'WERKS'.
      ltab_fields-selectflag = 'X'.
      APPEND ltab_fields.
      ltab_fields-tabname    = 'T001W'.
      ltab_fields-fieldname  = 'NAME1'.
      ltab_fields-selectflag = space.
      APPEND ltab_fields.
    *-- Fill values
      select * from t001w.
        ltab_values-feld = t001w-werks.
        append ltab_values.
        ltab_values-feld = t001w-name1.
        append ltab_values.
      endselect.
    CALL FUNCTION 'HELP_VALUES_GET_WITH_TABLE'
         EXPORTING

  • Comparing OO ALV and ALV using Function modules

    Hi All,
    Please provide me what are the advantages of developing ALV using Objects compared to creation using function modules. What are the disadvantages of creating using the conventional FM way.
    I have not worked much on ALV using Function modules, have been developing using standard abap classes. I wanted to have an detailed understanding and differences between the two.
    Please provide your views on the same.
    I have searched SDN forum, but didnt find much information, so it will be of great help if you provide some inputs.
    Thanks & Regards,
    Navneeth K.

    Hi, Navneeth,
    With ALV functions, you can everything that you would do otherwise with the OOPS ALV. However , I don't think you can possibily have more controls in case of alv function because it occupies the entire screen and the function only calls 2 screens internally ( screen numbers 500 and 700 (for popup alv)).
    But with OOPS on the other hand, you can have many controls on one screen, for example, you can have 2 ALV lists, or a splitter control with one of them having a Tree control and the other alv grid/list, pictures etc.
    So the sole motive of the function is if you want to display a list, but when developing a serious application, I  would go for OOPs ALV.
    regards,
    Advait

  • Printing ALV Report output through Function Modules

    Hi All,
    I want to print my ALV Grid output through function modules/statement (not through print option in menu).
    This is because, i am generating a PDF from spool when user clicks on a button. If any changes happened in the ALV output layout, they will be captured in spool through printing it.
    So can you please tell me how to print the ALV Output through FMs or sending the ALV output to spool.
    Thanks & Regards,
    Senthil.

    Hi Dev,
    Thanks for the reply.
    I want to print the ALV when the user clicks on a button in toolbar. Lets say the user has made some changes to the layout, (E.g hiding a field) and when i print that output it should use the changed layout, If i use the FM suggested by you, i cant acheive this.
    If you try to print this manually, the system uses the changed layout and not the original. Thats why i want to know FMs/statement to print.
    Regards,
    Senthil.
