  • Problem in handling double click in the second alv grid control

    Hi all,
    I have a screen. In the screen , I have 2 custom container and each custom container has 1 alv grid control.
    I need to handle double click event for both of alv grid controls in my screen.
    I defined 2 local event handler class for each alv grid and defined 2 handle_double_click event.
    In the first Alv grid double click works fine , everything is ok, world is peaceful.
    But in the second alvgrid, the row parameters (E_ROW, E_COLUMN, ES_ROW_NO) comes initial so i cannot handle it.
    All i need is to call a different transaction (displaying the equipment-IE03) when user double-click on a field in the second alv grid control. I tried to use hotspot_click event too but it does'nt give the row id either.
    I read some posts in the forms ([Double click event of alv grid control|Double click event of alv grid control]).
    I tried everything but nothing works.
    Please help. Your answers will be appreciated.

    Hello Eagle
    I am not sure where the problem lies in your case but sample report ZUS_SDN_THREE_ALV_GRIDS_01 shows that you can always find out the current cell after the double-click event (in any case you have the current cell already as IMPORTING parameters of the event):

  • How to make Authority Check for ALVGrid?!

    Hey mates,
    i got the problem which is mentioned in the headline. How can i make an authority check for my ALVGrid? I mean i want to restrict special functions to the matching users ( Display, Edit, Delete mode ).
    Would be cool if someone can help
    Regards Basti

    Hello Bastian
    A simple approach would be to define three different transactions (e.g. Z_MYALV01, Z_MYALV02, Z_MYALV03) for editing/deleting, editing only and displaying only. Add the following coding to the report displaying your ALV grid:
      CASE syst-tcode.
        WHEN gc_tcode_create.    " 01
          " Allow all grid functions
        WHEN gc_tcode_change.  " 02
          " Suppress grid functions for deleting rows
        WHEN gc_tcode_display.  " 03
          " Suppress grid functions for editing/deleting
        WHEN others.
          RETURN.
       ENDCASE.

  • SAP Gui 7.20 PLevel 3, ALV Problems with German Umlauts u00FCu00F6u00E4...

    Hi,
    we have updated our SAP Gui to version 7.20 lately and have some serious problems now with entering German Umlauts 'üöäÜÖÄß' into any editable ALV grid.
    This means when typing in e.g. 'ü', the grid immediately removes this character and replaces it by, well, by nothing. It just ignores this character at all.
    SAP Gui is currently at patch level 3 . The correct version is 7200.1.3.3190, build 1196830. Running German Windows XP clients with service pack 3. ERP is running SAP ECC 6.0.
    Is this a known problem? Has sbdy. a workaround this?
    Edit: Just found the release notes for SAP Gui 7.20 Lvl 3:
    2010/09/02     Texts get garbled while typing umlaut character in ALVGrid, Note 1503081
    This note, however, is not open for public view. OTH this means SAP was aware of this problem and tried to correct it to no avail so far.
    Thanks,
    Michael
    Edited by: Michael Fritz on Nov 19, 2010 11:19 AM

    Hi Martin,
    where did you get this info? Any official SAP note available? Do you encounter similar problems?
    We, too, noticed that uploading and downloading files from directories with German Umlauts, this fails now,too. There may be problems with files, too, however, we did not check this so far. The previous SAP Gui, I guess it was 7.10, didn't have any problems with this.
    I start wondering if SAP Germany have ever tested this? Or do they not use Umlauts anyway

  • Requrred screenshots for alvgrid display

    hi,
    i am the beginner  to ABA/4,
    i want to learn how to create alv reports .
    can u people help me?

    Hi Sravanthi
    WELCOME TO SDN COMMUNITY
    ALV is ABAP LIST VIEWER.
    To have more functionalities like totals, subtotals,logos,etc we choose ALVs compared to reports.
    Check this:
    Documentation on alv:
    you can check out:

    http://help.sap.com/saphelp_nw2004s/helpdata/en/43/41341147041806e10000000a1553f6/frameset.htm
    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 cat
    alog. 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:

    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.

    some theory regarding alv:
    This table tells ALV which events are processed by the caller by CALLBACK.
    The table of possible events per list type can be initialized using the module REUSE_ALV_EVENTS_GET.
    You can display the names of the constants in the type pools SLIS which represent the individual events using the individual test function in the function module
    REUSE_ALV_EVENT_NAMES_GET. Only events with a form routine name are processed.
    The table structure contains the fields:
    • IT_EVENTS-NAME
    Name of the Callback event.
    Possible Callback events:
    • Action
    USER_COMMAND USING R_UCOMM LIKE SY-UCOMM RS_SELFIELD TYPE SLIS_SELFIELD
    Process actions on the list
    As this is a frequently-used Callback event, the form routine can also be passed directly in the interface in the IMPORTING parameter I_CALLBACK_USER_COMMAND.
    PF_STATUS_SET USING RT_EXTAB TYPE SLIS_T_EXTAB
    If a user list status is to be set, it must be done in the form routine assigned to this event. The ALV function codes, which must not be active, are in the Parameter RT_EXTAB. This table must be passed with the SET PF-STATUS command (with inactive user function codes as well, if necessary).
    The STANDARD status of the function group SALV should be used as a template for a user-specific status.
    As this is a frequently-used Callback event, its form routine can also be passed directly in the interface in the IMPORTING parameter I_CALLBACK_PF_STATUS_SET.
    ITEM_DATA_EXPAND USING RS_SELFIELD TYPE SLIS_SELFIELD RFLG_ALL TYPE C
    Only relevant for hierarchical-sequential lists using the layout parameter IS_LAYOUT-EXPAND_FIELDNAME of the structure IS_LAYOUT.
    Exit for passing item entries (ITEM table) for a header record which was expanded interactively by the user.
    RS_SELFIELD-TABINDEX contains the header table index for which the item entries are to be put in the global item output table (T_OUTTAB_SLAVE). The Callback is only called if ALV has no items for a header which is to be expanded.
    RFLG_ALL is passed with 'X' if the user shows all items. The application must ensure that entries are not repeated in the item table. RS_SELFIELD is initial in this case.
    CALLER_EXIT USING RS_DATA Is called at the beginning of the function module to make special settings. It is not usually used.
    • List processing events
    IMPORTANT: The application Callback routine must not manipulate the internal output table and/or its header record. This restriction applies to all Callbacks which are called in the list output and run under the 'List processing events'.
    TOP_OF_LIST no USING parameter. Information output at the start of the list
    END_OF_LIST no USING parameter. Information output at the end of the list
    TOP_OF_PAGE no USING parameter
    Equivalent to the list processing TOP-OF-PAGE event
    END_OF_PAGE no USING parameter. Not available for hierarchical-sequential lists.
    Information output at the end of a page. This is only called for printing.
    TOP_OF_COVERPAGE no USING parameter
    The selection information and list status are output together (if they exist) on a separate page by default. See also the documentation of the parameters:
    IS_PRINT-NO_COVERPAGE
    IS_PRINT-NO_PRINT_SELINFOS
    IS_PRINT-NO_PRINT_LISTINFOS
    IS_LAYOUT-GET_SELINFOS
    The user can format the header area of the 'cover page' himself or herself by specifying a Callback routine for this event.
    END_OF_COVERPAGE no USING parameter
    Analogously to TOP_OF_COVERPAGE the user can add other information to the information output by ALV (selection information, list status) at this event.
    FOREIGN_TOP_OF_PAGE no USING parameter
    The Top-of-page event is always processed in ALV and is only passed to the caller via the Callback mechanism. This is still the case if the caller, e.g. by a user action, processes a branch list which was not formatted by ALV (e.g. a popup with additional information about the list record selected and displayed by ALV).
    In this case, top-of-page cannot be formatted by ALV analogously to the basic list, it must be handled completely by the caller. The event top-of-page still occurs in ALV. When ALV notices a top-of-page which was not caused by an ALV output, the form routine in FOREIGN_TOP_OF_PAGE is called.
    FOREIGN_END_OF_PAGE no USING parameter
    The event end-of-page is always processed in ALV and only passed to the caller via callback. This is still the case, e.g. when the caller processes a details list which was not formatted by ALV (e.g. a popup with further information about selected list records which were displayed by ALV).
    In this case, end-of-page cannot be formatted by ALV analogously to the basic list, it must be handled completely by the caller. The event end-of-page still occurs in ALV. When ALV notices an end-of-page that was not caused by an ALV output, the form routine in FOREIGN_END_OF_PAGE is called.
    BEFORE_LINE_OUTPUT USING RS_LINEINFO TYPE SLIS_LINEINFO
    Output information before each output line. Should only be used in justified cases because it costs a lot of performance.
    AFTER_LINE_OUTPUT USING RS_LINEINFO TYPE SLIS_LINEINFO
    Output information after each output line. Should only be used in justified cases because it costs a lot of performance.
    • Internal use only
    LIST_MODIFY USING R_TABNAME TYPE SLIS_TABNAME
    R_INDEX LIKE SY-TABIX
    R_INDEX_ITEM LIKE SY-TABIX
    R_INDEX_SUM LIKE SY-TABIX
    • IT_EVENTS-FORM
    Name of the form routine which should be called in the calling program at the event.
    Field_catalog:
    Field catalog with field descriptions
    2.7.1. Description
    Field catalog containing descriptions of the list output fields (usually a subset of the internal output table fields). A field catalog is required for every ALV list output.
    The field catalog for the output table is built-up in the caller's coding. The build-up can be completely or partially automated by calling the REUSE_ALV_FIELDCATALOG_MERGE module
    See also the documentation of the function module REUSE_ALV_FIELDCATALOG_MERGE.
    The minimal field catalog is documented under 'default'. The caller can use the other optional parameters to assign output attributes to a field which differ from the default.
    A field catalog need not be built-up and passed explicitly only under the following conditions:
    • The internal table to be output has the same structure as a Data Dictionary structure which is referred to in the internal table declaration using LIKE or INCLUDE STRUCTURE.
    • all fields in this structure are to be output
    • the structure name is passed to ALV in the parameter I_STRUCTURE_NAME.
    See also the documentation of the IMPORTING paramter I_STRUCTURE_NAME.
    Positioning
    • row_pos (row position)
    value set: 0, 1 - 3
    Only relevant if the list output is to be multi-line (two or three lines) by default.
    A multi-line list can also be defined by the user interactively if the default list is one-line.
    The parameter specifies the relative output line of the column in a multi-line list.
    • col_pos (column position)
    value set: 0, 1 - 60
    only relevant when the default relative column positions differ from the field catalog field sequence. The parameter specifies the relative column position of the field in the list output. The column order can be changed interactively by the user. If this parameter is initial for all field catalog entries, columns appear in the field catalog field sequence.
    Identification
    • fieldname (field name)
    value set: internal output table field name (required parameter)
    Name of the internal output table field which is described by this field catalog entry
    • tabname (internal output table)
    value set: SPACE, internal output table name
    This parameter is used in 'manual' field catalog build-up only for hierarchical-sequential lists.
    Name of the internal output table which contains the field FIELDCAT-FIELDNAME.
    Data Dictionary reference
    • ref_fieldname (reference field name)
    value set: SPACE, Data Dictionary field name
    Name of the Data Dictionary field referred to.
    This parameter is only used when the internal output table field described by the current field catalog entry has a reference to the Data Dictionary (not a program field), and the field name in the internal output table is different from the name of the field in the Data Dictionary. If the field names are identical, naming the Data Dictionary structure or table in the FIELDCAT-REF_TABNAME parameter is sufficient.
    • ref_tabname (reference table/structure field name)
    value set: SPACE, name of a Data Dictionary structure or table
    Structure or table name of the referred Data Dictionary field.
    This parameter is only used when the internal output table field described by the current field catalog entry has a Data Dictionary reference (not a program field).
    Reference to fields with currency/measurement unit
    Each internal output table sum or quantity field whose decimal places are to be formatted appropriately for the unit in the list must follow the convention:
    • the field is of data type QUAN or CURR (internal type P) (the field must really have this physical data type. Overwriting the physical data type with the parameter FIELDCAT-DATATYPE has no effect)
    • There is a field in the internal output table which contains the associated unit.
    • There is also an entry in the field catalog for the unit field.
    (If the unit is not to appear as a column in the list, and cannot be interactively displayed as a column, e.g. because it is always unambiguous and is therefore explicitly output by the caller in the list header, the field catalog units field entry can take the parameter FIELDCAT-TECH = 'X'.
    The association of a value field to a unit affects the output as follows:
    • appropriate decimal places display for the unit
    • an initialized field with a link to a non-initial unit is output as '0' for the unit (if FIELDCAT-NO_ZERO is initial). When this field is summed, this unit affects whether the units are homogeneous.
    • an initialized field with a link to an initial unit is output as SPACE. When this field is summed, the unit SPACE does not affect the homogeneity of the units.
    • When non-initial fields with an initial unit are summed, the unit SPACE is considered to be a unit.
    Link to currency unit
    • cfieldname (currency unit field name)
    value set: SPACE, output table field name
    Only relevant for amount columns with associated unit.
    Name of the internal output table field containing the currency unit associated with the amount field FIELDCAT-FIELDNAME. The field in FIELDCAT-CFIELDNAME must have its own field catalog entry.
    • ctabname (internal currency unit field output table)
    value set: SPACE, output table field name
    only relevant for hierarchical-sequential lists
    Name of the internal output table containing the FIELDCAT-CFIELDNAME field.
    Link to measurement unit
    • qfieldname (measurement unit field name)
    value set: SPACE, output table field name
    only relevant for quantity columns with unit link.
    Name of the internal output table field containing the measurement unit associated with the quantity field FIELDCAT-FIELDNAME.
    The field in FIELDCAT-QFIELDNAME must have its own field catalog entry.

    Column output options
    • outputlen (column width)
    value set: 0 (initial), n
    For fields with a Data Dictionary link this parameter can be left initial.
    For fields without a Data Dictionary link (program field) the parameter must be given the value of the desired field list output length (column width).
    initial = column width is the output length of the referred Data Dictionary field (domain).
    n = column width is n characters
    • key (key column)
    value set: SPACE, 'X' 'X' = kex field (key field output in color)

    • no_out (field in field list)
    value set: SPACE, 'X' 'X' = field is not displayed in the current list.
    The user can interactively choose the field for output from the field list.
    The user can display the contents of these fields at line level using the 'Detail' function.
    See also the 'Detail screen' documentation of the parameter IS_LAYOUT.
    • tech (technical field)
    value set: SPACE, 'X' 'X' = technical field
    Field cannot be output in the list and cannot be displayed interactively.

    'X' = column is colored with the default column highlight color.
    'Cxyz' = column is colored with a coded color:
    • C: Color (coding must begin with C)
    • x: color number
    • y: bold
    • z: inverse
    • hotspot (column as hotspot)

    value set: SPACE, 'X'
    Not relevant for block lists (output of several lists consecutively)
    'X' = column fixed (does not scroll horizontally)
    All columns to be fixed must have this flag, starting from the left. If a column without this flag is output, only the columns to the left of this column are fixed. The user can change the column fixing interactively. See also the documentation of the Layout parameter
    IS_LAYOUT-NO_KEYFIX of the IMPORTING paramter IS_LAYOUT.
    • do_sum (sum over column)
    value set: SPACE, 'X' 'X' = a sum is to be calculated over this internal output table field.
    This function can also be called by the user interactively.
    • no_sum (sums forbidden)
    value set: SPACE, 'X' 'X' = no sum can be calculated over this field, although the data type of the field would allow summing.
    • input (column ready for input)
    Function not available
    Format column contents
    • icon
    value set: SPACE, 'X' 'X' = column contents to be output as an icon.
    The caller must consider the printability of icons.
    • symbol
    value set: SPACE, 'X' 'X' = column contents are to be output as a symbol.

    • just (justification)
    value set: SPACE, 'R', 'L', 'C'
    Only relevant for fields of data type CHAR or NUMC
    ' ' = default justification for this data type
    'R' = right-justified output
    'L' = left-justified output

    The justification of the column header always follows the justification of the columns. Independent justification of the column neader is not possible.
    • lzero (leading zeros)
    value set: SPACE, 'X'
    Only relevant for fields of data type NUMC
    ALV outputs NUMC fields right-justified without leading zeros by default.
    'X' = output with leading zeros
    Note: If a NUMC field is output left-justified or centered by FIELDCAT-JUST, leading zeros are output. If the output of leading zeros is suppressed by a Data Dictionary reference ALPHA conversion exit, the output is always left-justified.
    • no_sign (no +/- sign) Only relevant for value fields
    value set: SPACE, 'X' 'X' = value output without +/ sign
    • no_zero (suppress zeros) Only relevant for value fields
    value set: SPACE, 'X' 'X' = suppress zeros
    • edit_mask (field formatting)
    value set: SPACE, template
    template = see documentation of WRITE formatting option USING EDIT MASK template
    The output conversion conv can be made by template = '== conv'.
    Texts
    The following text parameters should be specified for program fields without a Data Dictionary reference. The texts are taken from the Data Dictionary for fields with a Data Dictionary reference. If this is not desired, the text parameters can also be specified. The Data Dictionary texts are then ignored. If the user changes the column width interactively, the column header text with the appropriate length is always used. The interactive function 'Optimize column width' takes account of both the field contents and the column headers: if all field contents are shorter than the shortest column header, the column width depends on the column header.
    The 'long field label' is also used in display variant definition, sort, etc. popups.
    • seltext_l (long field label)
    • seltext_m (medium field label)
    • seltext_s (short field label)
    • reptext_ddic (header)
    analogous to the Data element maintenance 'Header'
    The specified text is not necessarily output in the list, an optimum among all texts is sought.
    • ddictxt (specify text)
    value set: SPACE, 'L', 'M', 'S'
    You can specify with values 'L', 'M', and 'S', the keyword that should always be used as column header. If the column width changes, no attempt is made in this case to find an appropriate header for the new output width.
    Parameters for program fields without Data Dictionary reference
    see also 'Text' parameters
    • datatype (data type)
    value set: SPACE, Data Dictionary data type (CHAR, NUMC,...)
    Only relevant for fields without Data Dictionary reference
    Program field data type
    • ddic_outputlen (external output length)
    value set: 0 (initial), n
    Only relevant for fields without Data Dictionary reference whose output is nevertheless to be modified by a conversion exit.
    Prerequisites:
    • FIELDCAT-EDIT_MASK = '==conv'
    see also the documentation of the parameter FIELDCAT-EDIT_MASK
    • FIELDCAT-INTLEN = n
    see also the documentation of the parameter FIELDCAT-INTLEN
    n = external format field output length
    The column width FIELDCAT-OUTPUTLEN need not be the same as the external format output length (FIELDCAT-DDIC_OUTPUTLEN).
    • intlen (internal output length)
    value set: 0 (initial), n
    Only relevant for fields without Data Dictionary reference whose output is nevertheless to be modified by a conversion exit.
    Prerequisites:
    • FIELDCAT-EDIT_MASK = '==conv'
    see also the documentation of the parameter FIELDCAT-EDIT_MASK
    • FIELDCAT-DDIC_OUTPUTLEN = n
    see also the documentation of the parameter FIELDCAT-DDIC_OUTPUTLEN
    n = internal format field output length
    • rollname (data element)
    value set: SPACE, Data Dictionary data element name
    F1 help can be provided for a program field without a Data Dictionary reference, or F1 help which differs from the Data Dictionary help can be provided for a field with a Data Dictionary reference, using this parameter.
    When F1 help is called for this field, the documentation of the specified data element is displayed.
    If the FIELDCAT-ROLLNAME is initial for fields with a Data Dictionary reference, the documentation of the data element of the referred Data Dictionary field is output.
    Others
    • sp_group (field group key)
    value set: SPACE, CHAR(1)
    Field group key.
    Keys are assigned to group names in the IT_SPECIAL_GROUPS parameter (see also the documentation of the parameter IT_SPECIAL_GROUPS).
    When such an assignment is made in the field catalog and in IT_SPECIAL_GROUPS, the fields are grouped correspondingly in the display variant popup.
    • reprep (Report/Report interface selection criterion)
    value set: SPACE, 'X'
    Prerequisites:
    • The system contains the Report/Report interface (function group RSTI, table TRSTI)
    • Parameter LAYOUT-REPREP = 'X'
    (see also the documentation of the parameter LAYOUT-REPREP of the IMPORTING parameter IS_LAYOUT )
    'X' = When the Report/Report interface is called, the value of this field is passed in the selected interface start record as a selection criterion.
    2.7.2. Default
    • The following entries are usually sufficient for internal table fields with a reference to a field defined in the Data Dictionary :
    • fieldname
    • ref_tabname
    Notes:
    ALV gets the remaining information from the Data Dictionary.
    If no relative column position (COL_POS) is specified, the fields are output in the list in the order in which they were added to the field catalog.
    REF_FIELDNAME need only be specifid when the name of the internal table field differs from the name of the referred Data Dictionary field.
    Information which is explicitly entered in the field catalog is not overwritten by information from the Data Dictionary.
    Priority rule:
    Entries in the field catalog have priority over differing entries in the Data Dictionary.
    • The following entries are usually sufficient for internal table fields without a reference to the Data Dictionary (program fields):
    • fieldname
    • outputlen
    • datatype
    • seltext_s
    • seltext_m
    • seltext_l
    Notes:
    F1 help can be provided for program fields by assigning a data element to the parameter ROLLNAME.
    If the parameters SELTEXT_S, SELTEXT_M, SELTEXT_L, and REPTEXT_DDIC contain appropriate field labels, the program field column headers are also adjusted appropriately when the column width changes

  • ALV field catalogue update problem

    Dear Friends;
    I have a problem with field catalog update of ALV grid. I have designed an initial screen for selections and there are two pushbuttons here. According to the pushbutton selection the field catalogue values change, ie. some fields are hidden etc. After the first selection this works but if i exit the second screen and go to the selection screen to change my selection the fieldcatalogue is not updated accordingly altough i call the relevant fm. i fill in fieldcat with fm LVC_FIELDCATALOG_MERGE.
    Can someone suggest a solution pls?
    Thx
    Ali

    Hi Ali,
    chk this excellent Link.

  • A problem with threads

    I am trying to implement some kind of a server listening for requests. The listener part of the app, is a daemon thread that listens for connections and instantiates a handling daemon thread once it gets some. However, my problem is that i must be able to kill the listening thread at the user's will (say via a sto button). I have done this via the Sun's proposed way, by testing a boolean flag in the loop, which is set to false when i wish to kill the thread. The problem with this thing is the following...
    Once the thread starts excecuting, it will test the flag, find it true and enter the loop. At some point it will LOCK on the server socket waiting for connection. Unless some client actually connects, it will keep on listening indefinatelly whithought ever bothering to check for the flag again (no matter how many times you set the damn thing to false).
    My question is this: Is there any real, non-theoretical, applied way to stop thread in java safely?
    Thank you in advance,
    Lefty

    This was one solution from the socket programming forum, have you tried this??
    public Thread MyThread extends Thread{
         boolean active = true;          
         public void run(){
              ss.setSoTimeout(90);               
              while (active){                   
                   try{                       
                        serverSocket = ss.accept();
                   catch (SocketTimeoutException ste){
                   // do nothing                   
         // interrupt thread           
         public void deactivate(){               
              active = false;
              // you gotta sleep for a time longer than the               
              // accept() timeout to make sure that timeout is finished.               
              try{
                   sleep(91);               
              }catch (InterruptedException ie){            
              interrupt();
    }

    You can also try to provide a greater Priority to your player thread so that it gains the CPU time when ever it needs it and don't harm the playback.
    However a loop in a Thread and that to an infinite loop is one kind of very bad programming, 'cuz the loop eats up most of your CPU time which in turn adds up more delays of the execution of other tasks (just as in your case it is the playback). By witting codes bit efficiently and planning out the architectural execution flow of the app before start writing the code helps solve these kind of issues.
    You can go through [this simple tutorial|http://oreilly.com/catalog/expjava/excerpt/index.html] about Basics of Java and Threads to know more about threads.

    N.B. And yes there are more articles and tutorials available but much of them targets the Java SE / EE, but if you want to read them here is [another great one straight from SUN|http://java.sun.com/docs/books/tutorial/essential/concurrency/index.html] .

  • J2ME problem with threads

    Hi all,
    I would like to ask you for a help. I need to write a small program at my university. I started to write a midlet which function would be to countdown time for sports activities. I woul like to start a new thread - the one that counts down - and at the same time make the main thread sleep.

    Groovemaker,
    Your Licznik class has a member m of type monitor, which has not been instantiated (in other words is null) hence, when calling m.put() you get NullPointerException. Please also mind, that using Thread.sleep(1000) is not an accurate way of measuring time.
    If I may, please use recommended for Java class naming conventions - some of your names use lower case, while other don't which is confusing to the reader.

  • Problem with threads within applet

    Hello,
    I got an applet, inside this applet I have a singleton, inside this singleton I have a thread.
    this thread is running in endless loop.
    he is doing something and go to sleep on and on.
    the problem is,
    when I refresh my IE6 browser I see more than 1 thread.
    for debug matter, I did the following things:
    inside the thread, sysout every time he goes to sleep.
    sysout in the singleton constructor.
    sysout in the singleton destructor.
    the output goes like this:
    when refresh the page, the singleton constructor loading but not every refresh, sometimes I see the constructor output and sometimes I dont.
    The thread inside the singleton is giving me the same output, sometime I see more than one thread at a time and sometimes I dont.
    The destructor never works (no output there).
    I don't understand what is going on.
    someone can please shed some light?
    thanks.
    btw. I am working with JRE 1.1
    this is very old and big applet and I can't convert it to something new.

    Ooops. sorry!
    I did.
         public void start() {

  • Problem with Threads and a static variable

    I have a problem with the code below. I am yet to make sure that I understand the problem. Correct me if I am wrong please.
    Code functionality:
    A timer calls SetState every second. It sets the state and sets boolean variable "changed" to true. Then notifies a main process thread to check if the state changed to send a message.
    The problem as far I understand is:
    Assume the timer Thread calls SetState twice before the main process Thread runs. As a result, "changed" is set to true twice. However, since the main process is blocked twice during the two calls to SetState, when it runs it would have the two SetState timer threads blocked on its synchronized body. It will pass the first one, send the message and set "changed" to false since it was true. Now, it will pass the second thread, but here is the problem, "changed" is already set to false. As a result, it won't send the message even though it is supposed to.
    Would you please let me know if my understanding is correct? If so, what would you propose to resolve the problem? Should I call wait some other or should I notify in a different way?
    Thanks,
    B.D.
    Code:
    private static volatile boolean bChanged = false;
    private static Thread objMainProcess;
       protected static void Init(){
            objMainProcess = new Thread() {
                public void run() {
                    while( objMainProcess == Thread.currentThread() ) {
                       GetState();
            objMainProcess.setDaemon( true );
            objMainProcess.start();
        public static void initStatusTimer(){
            if(objTimer == null)
                 objTimer = new javax.swing.Timer( 1000, new java.awt.event.ActionListener(){
                    public void actionPerformed( java.awt.event.ActionEvent evt){
                              SetState();
        private static void SetState(){
            if( objMainProcess == null ) return;
            synchronized( objMainProcess ) {
                bChanged = true;
                try{
                    objMainProcess.notify();
                }catch( IllegalMonitorStateException e ) {}
        private static boolean GetState() {
            if( objMainProcess == null ) return false;
            synchronized( objMainProcess ) {
                if( bChanged) {
                    SendMessage();
                    bChanged = false;
                    return true;
                try {
                    objMainProcess.wait();
                }catch( InterruptedException e ) {}
                return false;
        }

    Thanks DrClap for your reply. Everything you said is right. It is not easy to make them alternate since SetState() could be called from different places where the state could be anything else but a status message. Like a GREETING message for example. It is a handshaking message but not a status message.
    Again as you said, There is a reason I can't call sendMessage() inside setState().
    The only way I was able to do it is by having a counter of the number of notifies that have been called. Every time notify() is called a counter is incremented. Now instead of just checking if "changed" flag is true, I also check if notify counter is greater than zero. If both true, I send the message. If "changed" flag is false, I check again if the notify counter is greater than zero, I send the message. This way it works, but it is kind of a patch than a good design fix. I am yet to find a good solution.
    Thanks,
    B.D.

  • Problem with threads running javaw

    Hi,
    Having a problem with multi thread programming using client server sockets. The program works find when starting the the application in a console using java muti.java , but when using javaw multi.java the program doesnt die and have to kill it in the task manager. The program doesnt display any of my gui error messages either when the server disconnect the client. all works find in a console. any advice on this as I havent been able to understand why this is happening? any comment would be appreciated.
    troy.

    troy,
    Try and post a minimum code sample of your app which
    does not work.
    When using javaw, make sure you redirect the standard
    error and standard output streams to file.
    Graeme.Hi Graeme,
    I dont understand what you mean by redirection to file? some of my code below.
    The code works fine under a console, code is supposed to exit when the client (the other server )disconnects. the problem is that but the clientworker side of the code still works. which under console it doesnt.
    public class Server{
    ServerSocket aServerSocket;
    Socket dianosticsSocket;
    Socket nPortExpress;
    ClientListener aClientListener;

  • Problem with Threads and "plase wait..."-Window

    Hi everyone,
    I have a problem that I'm not able to solve in any way... I have a time-consuming task (a file decryption) which I execute in a separate thread; I've used the SwingWorker class, like suggested by sun-tutorial, and it works right. The problem is that I have to wait that the decryption have finished before continuing with program-execution. Therefore I would like to display a "please wait"-window while the task runs. I've tryed all the possible ways I know but the problem is always the same: the waitWindow is displayed empty, the bounds are painted but the contents no; it's only painted when the decrypt-task has finished. Please help me, I have no more resources....
    decrypt-file code:
    public class DecryptFile {
      private String cryptedFileNameAndPath;
      private ByteArrayInputStream resultStream = null;
      // need for progress
      private int lengthOfTask;
      private int current = -1;
      private String statMessage;
      public DecryptFile(String encZipFileNameAndPath) {
        cryptedFileNameAndPath = encZipFileNameAndPath;
        //Compute length of task...
        // 0 for indeterminate
        lengthOfTask = 0;
      public ByteArrayInputStream getDecryptedInputStream() {
        return this.resultStream;
       * Called from ProgressBarDemo to start the task.
      public void go() {
        current = -1;
        final SwingWorker worker = new SwingWorker() {
          public Object construct() {
            return new ActualTask();
        worker.start();
       * Called from ProgressBarDemo to find out how much work needs
       * to be done.
      public int getLengthOfTask() {
        return lengthOfTask;
       * Called from ProgressBarDemo to find out how much has been done.
      public int getCurrent() {
        return current;
      public void stop() {
        current = lengthOfTask;
       * Called from ProgressBarDemo to find out if the task has completed.
      public boolean done() {
        if (current >= lengthOfTask)
          return true;
        else
          return false;
      public String getMessage() {
        return statMessage;
       * The actual long running task.  This runs in a SwingWorker thread.
      class ActualTask {
        ActualTask () {
          current = -1;
          statMessage = "";
          resultStream = AIUtil.getInputStreamFromEncZip(cryptedFileNameAndPath); //here the decryption happens
          current = 0;
          statMessage = "";
      }The code that calls decryption and displays waitWindow
          final WaitSplash wS = new WaitSplash("Please wait...");
          final DecryptFile cryptedTemplate = new DecryptFile (this.templateFile);
          cryptedTemplate.go();
          while (! cryptedTemplate.done()) {
            try {
              wait();
            } catch (Exception e) { }
          this.templateInputStream = cryptedTemplate.getDecryptedInputStream();
          wS.close();Thanks, thanks, thanks in advance!

    Maybe you can try setting the priority of the long-running thread to be lower? so that the UI will be more responsive...

    please can someone help me out with this, is it an error on my part or do i have to set some option.

    Hi gandalf123,
    First, Thread.sleep is a static method, so you don't need to create a Thread object to use it.
    I think the problem is due to the fact you don't preverify your midlet.
    More over, you don't need to double post your question.

  • Problem with threads and camera.

    Hi everybody!
    I've a problem with taking snapshot.
    I would like to display a loading screen after it take snapshot ( sometimes i
    have to wait few seconds after i took snapshot. Propably photo is being taken in time where i have to wait).
    I was trying to use threads but i didn't succeed.
    I made this code:
    display.setCurrent(perform);               
            new Thread(new Runnable(){
                public void run() {               
                    while((!performing.isShown()) && (backgroundCamera.isShown())){
                        Thread.yield();
                    notifyAll();
            }).start();
            new Thread(new Runnable(){
                public void run() {
                    try {
                        this.wait();                   
                    } catch(Exception e) {
                        exceptionHandler(e);
                    photo = camera.snapshot();                               
                    display.setCurrent(displayPhoto);
            }).start();This code is sometimes showing performing screen but sometimes no.
    I don't know why. In my opinion performing.isShown() method isn't working correctly.
    Does anyone have some idea how to use threads here?

    Hi,
    I've finally managed to work this fine.
    The code:
           Object o = new Object();
           display.setCurrent(perform);               
            new Thread(new Runnable(){
                public void run() {               
                    while(!performing.isShown()){
                        Thread.yield();
                   synchronized(o) {
                      o.notify();
            }).start();
            new Thread(new Runnable(){
                public void run() {
                    try {
                        synchronized(o) {
                           o.wait(1);
                    } catch(Exception e) {
                        exceptionHandler(e);
                    photo = camera.snapshot();                               
                    display.setCurrent(displayPhoto);
            }).start();
