Dialog Screen - Invalid field format (screen error)

Dear all,
  I have developed a modal dialog screen and succesfully invoked it with CALL SCREEN command in the main screen.  Unfortunately, it always returns "Invalid field format (screen error)" when clicking on the dialog's GUI control such as button or radio button.  Anyone encountered this before??
Regards,
KK

Hi KK,
Just make sure that the fields take on the screen are also declared in the top module of your program.
And also match their data-types and size i.e., declared in top module and on the screen in their respective attributes.
Hope this solves your problem.
Thanks & Regards,

  • Invalid field format (screen error) on Table Control

    Hello,
    When selecting a line or multiple lines on a screen made by me(using a Table Control), I get Invalid field format (screen error). Debugging the code it sends the message when looping the internal table on PAI to check if there were values changed. Is there a reason why this error appears on this?
      loop at it_values.
        chain.
          field pvalues-BEGDA.
          module CHANGE_QUEUE.
        endchain.
      endloop.
    Thanks.

    No need to loop to check whether data is changed after PBO, just check System Field SY-DATAR, it will be set to 'X' if any field was changed.
    So the following code is enough;
    IF SY-DATAR EQ 'X'.
       PERFORM SAVE_DATA.
    ENDIF.

  • Error Invalid field format (screen error) in module pool

    Hi
    experts i am doing module in whichi had many check boxes on screen and each check box has function code means i want to do some thing else . but as i click the first or any other check box i get a error message
    INVALID FIELD FORMAT (SCREEN ERROR).
    Can anyody help me with this asnwers will be rewarded points .
    regards

    Dear Farukh,
    can you please let me know how have you declared you check boxes.
    how did you handle the click or the function codes in the user command module in your PAI.
    The declaration of your fucntion codes can be done when you create your screen fields and then they need to be handled in the user command module i.e what you want to do when suppose you click on that particular check box.
    Thanks

  • Invalid field format (screen error)

    We are using custom module pool report for displaying information. Information display in Table control which has also Radio button option for the further processing. After unicode conversion we are getting error while accessing the screen as "Invalid field format (screen error)" when user select Radio button. In production environment we are not facing any issue, but in Dev + Qas we have this issue. Nothing is changed as all environment are sync. To solve the issue we re-defined the Radion screen element, but no success we are still getting same error. I am not sure whether it is related to Page Format or something else. Could you please let me know whether anybody faced this issue ? For the information, I already searched on SDN and SNote, but there is no post or SNote

    Have you checked if there are overlapping fields on the screen.
    I've seen simular errors and usually it was beacuse of some change by SAP that made it so that the defined length of the screen field was suddenly to small.
    I'm not saying that this is the case in your situation, but it never hurts to try and change the length of your screen field and see if that resolves the issue.

  • Search Help error : Invalid field format Screen error

    Hi All,
    I have attached a search help to contract field for contract no and item number. (in my own screen developed in a  report)
    The search help picks up data and assigns it to the fields,
    But after this when I click on any other button, I get error saying :
    <b>Invalid Field Format (Screen Error) !!!</b>
    Any pointers guys !!!
    Warm Regards,
    Girish

    screen checks in abapautomatically checks for format of field when u enter data....i.e date, integer etc...the problem in this case is that when u seelct a value using the help it is filling a value which is not the correct format...so check for the data types and test it again...this is definitely the problem.

  • Getting "... file has and invalid format. (Error no. 11)" when importing .tdms file into DIAdem 11

    I developed a script for processing .tdms files in DIAdem 11.1, now I'm deploying the script on the very PXI system that created the .tdms files.  This system had DIAdem 11.0, but when I try to open (DataFileLoadSel) the tdms file in my script I get the error message:
    "D:\MyFileName.tdms" has an invalid fiel format.  (Error no. 11)
    The tdms files are created by a LabView application.
    If I delete the correspondin .tdms index file, I get a little further, it loads the first two of four groups, using DataFileLoadSel on the first group, and DataFileLoadRed on the 2nd group, on third group, another DataFileLoadRed, I get the following error:
    Error in <MyScript> (Line: x, Column: y):
    Cannot load the file "D:\MyFileName.tdms" with the loader "TDMS"
    Further information:
    Cannot open the file "D:\MyFileName.tdms".
    Is there a difference between DIAdem 11.0 and 11.1 that affects the import of .tdms files, if so, can I get around it?
    Thanks,
    Eric
    Solved!
    Go to Solution.

    Hello eberg,
    Before we go into more detailed error trapping, could you please try to install the TDMS 2.0 format on the DIAdem 11.0 computer (DIAdem 11.1 and LabVIEW 2009 come with the TDMS 2.0 stuff already installed).
    Please get the download here: http://zone.ni.com/devzone/cda/tut/p/id/9995
    Once installed, please try running the Scripts again (in DIAdem 11.0) and let us know if that fixed the issue. It might not help to install this, but it's a quick thing to try before we dig deeper into the issue.

  • Enabling custom field in screen after error msg

    HI experts,
    I m facing problem in enabling screen field in infotype screen. That is, i have added a custom field in std infotype screen and this is shown in enable mode by default. In PA30, im enterig values for all fields in the infotype and press SAVE.
    At that time, an error message is thrown by the system. Becoz of this error message, my custom field is changed to disable mode and also gets shrinked.
    Can anyone suggest me how to enable my own field in screen even after the error msg returned by the system?

    There are two ways to cater such a kind of problem.
    either you can enable custom field manually by writing code or
    you can change field group.

  • Fields from screen are not known by program.

    Hi All.
    I have this problem since I started using Dialog programming.
    Since I didn't attended any course I might be doing something wrong.
    When you define a field in a Dialog screen and you want to refer to it in the program that calls that screen you get a compilation error that there is no such field.
    If you define the field as at TABLE-FIELD you can work around this compilation issue by defining the TABLE using "tables: TABLE" statement, but now I have a problem since I don't want to use the TABLE-FIELD definition for my field and thus I'm stuck Shocked
    Any help will be appreciated.
    Ayal.

    Hai,
    If suppose, if you define a field in the screen, it is not mandatory to declare same variable in program level.  If we take the same name, after completion of PBO the data automatically transferred to the screen field. If u don't take the same name then you need to pass value of the variable to the screen field in the PBO.
    Example :
    If suppose, you have a I/O field in the screen with name TEXT.
    In the program
    data : text(10) type C.
    if that is 100 screen.
    Process before output.
    module display_100.
    with in this module
    text = 'SRIKANTH'.
    this will directly display on the screen.

  • AT SELECTION-SCREEN-ON FIELD  event IN ALV

    Hai all,
               Is there any event in ALV similar to AT SELECTION-SCREEN-ON FIELD  .
    if so how can this be achieved ,pls give me an example .
    Regards,
    Dev

    Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output. Cases arise in sap when the output of a report contains columns extending more than 255 characters in length. In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. This is a very efficient tool for dynamically sorting and arranging the columns from a report output. The report output can contain upto 90 columns in the display with the wide array of display options.
    The commonly used ALV functions used for this purpose are;
    1. REUSE_ALV_VARIANT_DEFAULT_GET
    2. REUSE_ALV_VARIANT_F4
    3. REUSE_ALV_VARIANT_EXISTENCE
    4. REUSE_ALV_EVENTS_GET
    5. REUSE_ALV_COMMENTARY_WRITE
    6. REUSE_ALV_FIELDCATALOG_MERGE
    7. REUSE_ALV_LIST_DISPLAY
    8. REUSE_ALV_GRID_DISPLAY
    9. REUSE_ALV_POPUP_TO_SELECT
    The different steps used for getting the above function modules into use are:
    Step 1
    DATA DECLARATION
    Sap standard type pools: SLIS , KKBLO .
    Sap standard tables types taken from the type pools are: SLIS_LAYOUT_ALV ,
    SLIS_T_FIELDCAT_ALV,
    SLIS_T_LISTHEADER,
    SLIS_T_EVENT,
    SLIS_SELFIELD.
    Internal tables to used in the program declared based on the above table types
    DATA: I_LAYOUT TYPE SLIS_LAYOUT_ALV,
    I_FIELDTAB TYPE SLIS_T_FIELDCAT_ALV,
    I_HEADING TYPE SLIS_T_LISTHEADER,
    I_EVENTS TYPE SLIS_T_EVENT.
    TYPES: KKBLO_SELFIELD TYPE SLIS_SELFIELD.
    Step 2 (Optional)
    SELECTING THE VARIANTS FOR INITIAL LIST DISPLAY (DEFAULT VARIANT)
    The variants in the list display can be both user-specific and general. The user can programmatically set the initial (default) variant for list display.
    The default variant can be found using the function module 'REUSE_ALV_VARIANT_DEFAULT_GET'.
    Sample code:
    CALL FUNCTION 'REUSE_ALV_VARIANT_DEFAULT_GET'
    EXPORTING
    i_save = variant save condition ( A=all, U = user-specific )
    CHANGING
    cs_variant = internal table containing the program name (and the default variant---optional )
    EXCEPTIONS
    not_found = 2.
    The user can also choose from the list of existing variants using the function module ‘REUSE_ALV_VARIANT_F4’.
    Step 3
    DEFININING OUTPUT CHARACTERISTICS: PREPARING DISPLAY FIELDS CATALOG
    A field catalog is prepared using the internal table (I_FIELDCAT) of type SLIS_T_FIELDCAT_ALV. 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 to add desired functionality (i.e. Key, Hotspot, Specific headings, Justify, Col. position etc) to certain fields of the output. If not mentioned specifically, then the defaults are taken. The possible values and defaults are listed below.
    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.
    The minimal field catalog is documented below. This can be done in a routine using a local variable. The user can use the other optional parameters to assign output attributes to different fields in the output, which differ from the default.
    A field catalog need not be built-up and passed explicitly only under the following conditions:
    1. 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. In this case the attributes of the different fields is taken directly from the table and the attributes (key fields, length, texts etc) need to state explicitly.
    2. all fields in this structure are to be output
    3. The structure name is passed to ALV in the parameter I_STRUCTURE_NAME of the function module REUSE_ALV_LIST_DISPLAY.
    All the values entered in the catalog is specific to the particular field whose name is entered in the fieldname FIELDNAME of the fieldcat structure. The name of the table is also entered in the corr. Fieldname TABNAME of the structure.
    The different possible attributes are:
    • Row_pos (row position): Only relevant if the list output is to be multi-line (two or three lines) by default. So, this attribute can be used maintain certain level of alignment in the output.
    Value set: 0, 1 – 3
    • Col_pos (column position): This parameter is relevant when the fields in the output are to be different from the sequence of the fields in the internal table used for display. 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 internal table field sequence.
    Value set: 0, 1 – 60
    • Fieldname (field name): This is the name of the internal table field for which the parameters are passed in the catalog.
    Value set: internal output table field name (required parameter)
    • Tabname (internal output table): Name of the internal output table that contains the field FIELDCAT-FIELDNAME above.
    Value set: SPACE, internal output table name.
    • Ref_fieldname (reference 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.
    Value set: SPACE, Data Dictionary field name.
    • Ref_tabname (reference table/structure field name): 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).
    Value set: SPACE, name of a Data Dictionary structure or table
    Link to currency unit
    • Cfieldname (currency unit field name): This is used for currency fields that have a reference to any unit field. This is only relevant for amount columns with associated unit. This parameter contains the 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.
    Value set: SPACE, output table field name
    • Ctabname (internal currency unit field output table): Name of the internal output table containing the FIELDCAT-CFIELDNAME field.
    Value set: SPACE, output table field name.
    Link to measurement unit
    • Qfieldname (measurement unit 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.
    Value set: SPACE, output table field name.
    • Qtabname (internal measurement unit field output table): Name of the internal output table containing the FIELDCAT-QFIELDNAME field.
    Value set: SPACE, output table field name.
    • Outputlen (column width): This parameter is used if the desired output length for a field is desired to be different from the internal output table field. 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.
    Value set: 0 (initial), n.
    • Key (key column): By default, the system makes some fields in the output as key fields, provided the fields are key fields in their referencing table. Using this parameter, fields other than key fields of the referencing table can be made key field. This parameter is most important if the output needs to contain some field which are not scrollable or cannot be hidden.
    If the internal output table contains fields that are key fields from different tables, then all those fields in the report output becomes unscrollable and cannot be hidden. So, the fields in the output internal table should not be referenced from tables in which they are key fields. Instead, they should be referenced to the tables in which they are not key fields, incase they are not desired as key field in the output.
    'X' = key field (key field output in color) and Key fields can not be interactively hidden. Parameter FIELDCAT-NO_OUT must be left initial.
    Value set: SPACE, 'X'.
    • Key_sel (hideable key column): This parameter is only relevant for the fields which are made key fields using FIELDCAT-KEY = 'X'. Using this parameter the Key field can be hidden interactively.
    The key column sequence cannot be changed interactively by the user. The output is controlled by the FIELDCAT-NO_OUT parameter analogously to non-key fields.
    Value set: SPACE, 'X'.
    • No_out (field in field list): This parameter is used to remove certain fields from the output during initial display. The user can however interactively choose the field for output from the field list in the display variant.
    'X' = field is not displayed in the current list.
    Value set: SPACE, 'X'.
    • Tech (technical field): This parameter is used to make certain field display only in the field catalog. The fields with this parameter set cannot be output in the list nor can they be displayed interactively from the catalog.
    'X' = technical field.
    Value set: SPACE, 'X'.
    • Emphasize (highlight columns in color): As name suggests, this field parameter is used to highlight certain field with chosen colors.
    Value set: SPACE, 'X' or 'Cxyz' (x:'1'-'9'; y,z: '0'=off ,'1'=on).
    '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): This parameter is used to make certain field appear as hotspot i.e. a hand is displayed if the cursor is positioned on the field value. Single click on such fields cause the PICK OR F2 events to happen.
    Value set: SPACE, 'X'.
    'X' = column cells are output as hotspots.
    • Fix_column (fix column): This parameter is used to fix certain columns in the output. 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.
    Value set: SPACE, 'X'.
    'X' = column fixed (does not scroll horizontally).
    • Do_sum (sum over column): the user can also call this function interactively.
    Value set: SPACE, 'X'.
    'X' = a sum is calculated over this internal output table field.
    • No_sum (sums forbidden): No sum can be calculated over this field, although the data type of the field would allow summing.
    Value set: SPACE, 'X'.
    • Icon: The parameter displays certain column contents as icons. The internal output table column contents must be valid icon strings.
    Value set: SPACE, 'X'.
    'X' = column contents to be output as an icon.
    • Symbol: The internal output table column must be a valid symbol character.
    Value set: SPACE, 'X'
    'X' = column contents are to be output as a symbol.
    • Just (justification): This parameter is used for alignment of the contents of the output table. This is only relevant for CHAR or NUMC fields in the output internal table. The justification of the column header always follows the justification of the columns. Independent justification of the column header is not possible.
    Value set: SPACE, 'R', 'L', and ‘C’.
    ' ' = Default justification for this data type
    'R' = right-justified output
    'L' = left-justified output
    'C' = centered output.
    • Lzero (leading zeros): By default ALV outputs NUMC fields right-justified without leading zeros. Using this parameter only the NUMC fields can be displayed with leading zeroes.
    Value set: SPACE, 'X'.
    'X' = output with leading zeros.
    • No_sign (no +/- sign): This parameter is used to suppress the signs of the output fields. It is only relevant for the 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): To apply the report output formatting options same as in the WRITE statement in report writing.
    Value set: SPACE, template.
    The following parameters are used for customizing the texts in the heading of the output of the columns. 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. Popup.
    • seltext_l (long field label)
    • seltext_m (medium field label)
    • seltext_s (short field label)
    • reptext_ddic(header) Analogous to the Data element main header
    • Ddictxt (specify text) : 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.
    Value set: SPACE, 'L', 'M', and ‘S’.
    Sample code:
    Suppose I_PO_DETAILS is an internal table containing two fields EBELN (PO number) and EBELP (PO item no).
    DATA: L_FIELDCAT TYPE SLIS_FIELDCAT_ALV. “Local variable to hold the parameters
    for a particular field of the field catalog
    CLEAR L_FIELDCAT.
    L_FIELDCAT-TABNAME = 'I_PO_DETAILS'.
    L_FIELDCAT-FIELDNAME = 'EBELN'.
    L_FIELDCAT-KEY = 'X'. “The PO no is made the key field,
    “Colored and non scrollable
    L_FIELDCAT-HOTSPOT = 'X'. “The po no becomes a hotspot
    L_FIELDCAT-SELTEXT_S = ‘P.O No’.
    L_FIELDCAT-SELTEXT_M = 'P order No'.
    L_FIELDCAT-SELTEXT_L = 'Purchase order No'.
    APPEND L_FIELDCAT TO I_FIELDTAB.
    CLEAR L_FIELDCAT
    L_FIELDCAT-TABNAME = 'I_PO_DETAILS'.
    L_FIELDCAT-FIELDNAME = 'EBELN'.
    L_FIELDCAT-KEY = 'X'. “The po item no is made the key field,
    “Colored and non scrollable
    L_FIELDCAT-SELTEXT_S = 'Item No'.
    L_FIELDCAT-SELTEXT_M = 'Item No`.
    L_FIELDCAT-SELTEXT_L = 'PO Item No'.
    APPEND L_FIELDCAT TO I_FIELDTAB.
    CLEAR L_FIELDCAT
    Thus the catalog for the report output is prepared.
    Step 4
    The next step is to build an event table, which are used for firing both user commands and the system dependent events i.e. top of page, end of page etc.
    A list of possible events is populated into an event table (I_EVENTS) when this table is passed to the function module REUSE_ALV_EVENT_NAMES_GET. The return table from this function module contains all the possible events.
    The function module contains following import and export parameters.
    IMPORTING PARAMETERS: I_LIST_TYPE
    This parameter has possible values from 0-4.
    The parameter I_LIST_TYPE is of TYPE SLIS_LIST_TYPE and is DEFAULT 0 .
    EXPORTING PARAMETERS: I_EVENTS table.
    This table is of TYPE SLIS_T_EVENT and returns to the program the name of all the possible events.
    The table structure contains the fields:
    I_EVENTS-NAME: Name of the Callback event.
    I_EVENTS-FORM: Name of the form routine that should be called in the calling program at the event.
    Only events with a form routine name are processed.
    The I_EVENTS table returns with the following possible constants:
    1. Slis_ev_item_data_expand TYPE slis_formname VALUE 'ITEM_DATA_EXPAND'.
    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 that was expanded interactively by the user.
    2. Slis_ev_reprep_sel_modify TYPE slis_formname VALUE 'REPREP_SEL_MODIFY'.
    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 that 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.
    3. Slis_ev_caller_exit_at_start TYPE slis_formname VALUE 'CALLER_EXIT'.
    Is called at the beginning of the function module to make special settings. It is not usually used.
    4. Slis_ev_user_command TYPE slis_formname VALUE 'USER_COMMAND'.
    As this is a frequently-used Callback event, the form routine can also be passed directly in the interface by passing the user command in the IMPORTING parameter I_CALLBACK_USER_COMMAND.
    5. Slis_ev_top_of_page TYPE slis_formname VALUE 'TOP_OF_PAGE'.
    Equivalent to the list processing TOP-OF-PAGE event.
    6. Slis_ev_top_of_coverpage TYPE slis_formname VALUE 'TOP_OF_COVERPAGE'.
    The selection information and list status are output together (if they exist) on a separate page by default
    7. Slis_ev_end_of_coverpage TYPE slis_formname VALUE 'END_OF_COVERPAGE'.
    Analogously to TOP_OF_COVERPAGE the user can add other information
    to the information output by ALV (selection information, list status) at this event.
    8. Slis_ev_foreign_top_of_page TYPE slis_formname VALUE ‘FOREIGN_TOP_OF_PAGE'.
    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.
    9. Slis_ev_foreign_end_of_page TYPE slis_formname VALUE 'FOREIGN_END_OF_PAGE'.
    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.
    10. Slis_ev_pf_status_set TYPE slis_formname VALUE 'PF_STATUS_SET'.
    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.
    11. Slis_ev_list_modify TYPE slis_formname VALUE 'LIST_MODIFY'.
    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.
    12. Slis_ev_top_of_list TYPE slis_formname VALUE 'TOP_OF_LIST'.
    Information output at the start of the list
    13. Slis_ev_end_of_page TYPE slis_formname VALUE 'END_OF_PAGE'.
    Information output at the end of a page. This is only called for printing.
    14. Slis_ev_end_of_list TYPE slis_formname VALUE 'END_OF_LIST'.
    Information output at the end of the list
    15. Slis_ev_after_line_output TYPE slis_formname VALUE 'AFTER_LINE_OUTPUT'.
    Output information after each output line. Should only be used in justified cases because it costs a lot of performance.
    16. Slis_ev_before_line_output TYPE slis_formname VALUE 'BEFORE_LINE_OUTPUT'.
    Output information before each output line. Should only be used in justified cases because it costs a lot of performance.
    17. Slis_ev_subtotal_text TYPE slis_formname VALUE 'SUBTOTAL_TEXT'.
    This event table (I_EVENTS) is now checked with the desired constants. If the desired constant is found, then the corresponding field for the FORM NAME is populated with the name of the routine containing the corresponding event.
    Sample code :
    FORMNAME_TOP_OF_PAGE TYPE SLIS_FORMNAME VALUE 'TOP_OF_PAGE',
    FORMNAME_END_OF_PAGE TYPE SLIS_FORMNAME VALUE 'END_OF_PAGE', FORMNAME_USER_COMMAND TYPE SLIS_FORMNAME VALUE 'USER_COMMAND'.
    DATA: L_I_EVENT TYPE SLIS_ALV_EVENT.
    CALL FUNCTION 'REUSE_ALV_EVENTS_GET'
    EXPORTING
    I_LIST_TYPE = 0
    IMPORTING
    ET_EVENTS = I_EVENTS.
    READ TABLE I_EVENTS WITH KEY NAME = SLIS_EV_TOP_OF_PAGE
    INTO L_I_EVENT.
    IF SY-SUBRC = 0.
    MOVE FORMNAME_TOP_OF_PAGE TO L_I_EVENT-FORM.
    APPEND L_I_EVENT TO I_EVENTS.
    ENDIF.
    READ TABLE I_EVENTS WITH KEY NAME = SLIS_EV_END_OF_PAGE
    INTO L_I_EVENT.
    IF SY-SUBRC = 0.
    MOVE FORMNAME_END_OF_PAGE TO L_I_EVENT-FORM.
    APPEND L_I_EVENT TO I_EVENTS.
    ENDIF.
    CLEAR L_I_EVENT.
    READ TABLE I_EVENTS WITH KEY NAME = SLIS_EV_USER_COMMAND
    INTO L_I_EVENT.
    IF SY-SUBRC = 0.
    MOVE FORMNAME_USER_COMMAND TO L_I_EVENT-FORM.
    APPEND L_I_EVENT TO I_EVENTS.
    ENDIF.
    This will prepare the events table for the report.
    The report will contain three forms for the above events:
    1. FORM TOP_OF_PAGE : This form will contain the top of page event for the report i.e header etc
    Using the function module ‘REUSE_ALV_COMMENTARY_WRITE’, the internal table containing the headings for top of page event can be passed to the list output. Also, any logo specific to the report can be passed to the function module.
    2. FORM END_OF_PAGE : This form will contain the end of page event for the report i.e footer etc
    3. FORM USER_COMMAND : This form will contain the desired user command i.e pick/line selection
    Step 5
    A layout is build for the report output list description USING the internal table declared above (I_LAYOUT).

    X = color number ('1'-'9')
    Y = bold ('0' = off, '1' = on)
    46. Coltab_fieldname TYPE slis_fieldname: Cells can be colored individually using a color code which is contained in a column of the internal output table for the record containing the cell. Assign the name of the field to this parameter.
    Others
    47. List_append(1) TYPE c : no call screen. It is only useful to output block-lists without specifying the above modules if the number of list blocks exceeds, or may exceed, the maximum number specified in the block module documentation. These operations are not possible for user-defined block lists.
    Example code :
    I_LAYOUT-f2code = ws_fcode.
    I_LAYOUT-zebra = 'X'.
    I_LAYOUT-colwidth_optimize = 'X'.
    I_LAYOUT-no_keyfix = 'X'.
    I_LAYOUT-get_selinfos = 'X'.
    I_LAYOUT-no_hotspot = 'X'.
    I_LAYOUT-no_input = 'X'.
    I_LAYOUT-hotspot_fieldname = FIELDNAME.
    I_LAYOUT-no_input = ‘X’.
    I_LAYOUT-no_vline = `X’.
    I_LAYOUT-no_colhead = ‘ ‘.
    I_LAYOUT-lights_condense = ` `.
    I_LAYOUT-totals_text = ` `.
    I_LAYOUT-subtotals_text = ` `.
    I_LAYOUT-totals_only = ` `.
    I_LAYOUT-key_hotspot = ‘X’.
    I_LAYOUT-detail_popup = ‘X’.
    I_LAYOUT-group_change_edit = ‘X’.
    I_LAYOUT-GROUP_BUTTONS = ‘X’.
    Step 6
    This step is required to get the selection screen information in the report output.
    The prerequisite for this is to set the parameter LAYOUT-GET_SELINFOS of the IMPORTING structure.
    The parameters to be passed in the IS_SEL_HIDE table are:
    o mode: 'R' = only the entries passed in the internal table IS_SEL_HIDE-T_ENTRIES
    Are output in the pop up. Selection info, which the list tool read in the selection screen (when called by a report with a selection screen), is replaced by the values passed.
    'S' = the selection info which the list tool read in the selection screen of the calling report are modified by the entries in the table IS_SEL_HIDE-T_ENTRIES.
    o t_entries: Selection info table
    o t_entries-mode: 'A' = output the selection info for the current table record in the info popup.
    'D' = do not output select option or SELNAME parameter selection info in the popup.
    o t_entries-selname: (only used in t_entries-mode = 'D') : Name of the select option or parameter.
    The following table fields are only used in t_entries-mode = 'A'. They contain the selection information to be added.
    • t_entries-field: DDIC field name of the field for which selection information is to be output.
    • t_entries-table: DDIC table names of t_entries-field.
    • t_entries-stext: Field name in info popup.
    • If t_entries-field and t_entries-table have been entered, this text is taken from DDIC.
    • t_entries-valuf: Selection condition 'from' value (external format)
    • t_entries-valut: Selection condition 'to' value (external format)
    • t_entries-sign0: (I)nclusive (E)xclusive
    • t_entries-option: All values of the select options Option field allowed.
    Step 6
    The Table IT_SORT is populated with the sort criteria for the different fields.
    The caller specifies the sorting and/or subtotaling of the basic list in the internal table IT_SORT.
    This internal table has the following fields:
    o spos : Sort sequence
    o fieldname : Internal output table field name
    o tabname : Only relevant for hierarchical-sequential lists. Name of the internal output table.
    o up : 'X' = sort in ascending order
    o down : 'X' = sort in descending order
    o subtot : 'X' = subtotal at group value change
    o group : '* ' = new page at group value change ,'UL' = underline at group value change
    Step 7
    The final step in the output of the report is the use of two ALV functions modules.
    1. REUSE_ALV_FIELDCATALOG_MERGE
    2. REUSE_ALV_LIST_DISPLAY
    The first function module is used to pass the field catalog to the report output and merge it with the internal output table.
    FUNCTION reuse_alv_fieldcatalog_merge.

    The variant based on a program-internal table should only be used for rapid prototyping since the following restrictions apply:
    1. Performance is affected since the code of the table definition must always be read and interpreted at runtime.
    2. Dictionary reference are only considered if the keywords LIKE or INCLUDE STRUCTURE (not TYPE) are used.

  • How to add a search help on a screen field from screen painter

    Hi,
    I would like to add an existing Search Help on a screen field in Screen painter.
    Of course it's possible to just click on th screen field and in the property box, I just have to set the name of teh search help.
    The problem is that I need the screen field to be grey and user musn't be able to change the field value if he doens't use the search help.
    I'm not allowed to modify the existing search help or to built it on my own from source code, I must use the existing one.
    Do you have an idea on how to do so?
    Regards,
    Morgan

    Dropdown Box:
    In the screen painter for that field goto properties -> Dropdown ->select listbox.
    Option 1:
    Instead let that field be in change mode and if user enters any wrong entry which is not there in the table give a error messgae.
      CHAIN.
        FIELD addr1_data-country.
        MODULE modify_screenfields1.
      ENDCHAIN.
    MODULE modify_screenfields1 INPUT.
      CASE sy-ucomm.
        WHEN 'ENTER' OR 'EXECUTE'.
          IF NOT addr1_data-country IS INITIAL.
            SELECT SINGLE landx FROM t005t INTO lws_landx WHERE
                                          land1 = addr1_data-country
                                      AND spras = 'EN'.
            IF sy-subrc <> 0.
              MESSAGE e000(zo_spa) WITH text-022.  " Invalid Country code
            ELSE.
              t005t-landx = lws_landx.
            ENDIF.
          ELSE.
            CLEAR: t005t-landx.
          ENDIF.
       ENDCASE.
    ENDMODULE.                 " modify_screenfields1  INPUT
    Option 2: Other than if u want the way u like, let that field be greyed out. don't attach the search help.
    In the PROCESS ON VALUE-REQUEST.
      FIELD addr1_data-region MODULE region_pov.
    MODULE region_pov INPUT.
    Using the F4IF_INT_TABLE_VALUE_REQUEST table value request show the search help.
    also make that field input enabled.
    ENDMODULE.                 " region_pov  INPUT
    I think this will solve ur problem.

  • How to provide validation for a particular field of screen

    Hi Experts,
    For my project, I have created a screen. In the screen, we have one field. For this field we have provided F4 help. When the user clicks on the F4 list of values is displayed.
    I have to provide following condition for this field.
    User should only select values from this F4 list only. If the user tries to enter any data which is not contained in the list, system should throw message that 'Invalid data. Select valid values".
    Can you please let me know how I can do so?
    The relevant portion of code is

    Hi,
    Try this.
    Create an internal table and populated it with the values present in the F4 help of the field. Then in AT SELECTION-SCREEN event check the value of the field with the values in the internal table and display the appropriate message.
    Sharin.

  • Use of enhancement to add field in screen

    please explain me how to add fields in standard transaction screen by using enhancement 6 in version 6.0 ?

    SAP provides standard transactions to enter data into database. But a client may want to maintain some additional information in SAP other than what is provided.
    To make provisions for this, additional screens have to be provided and additional fields must be added into appropriate database table.
    To pave way for this, SAP has provided the option for screen exits. Usually, SAP provides the following:
    An append structure in the database table with the new fields.
    A subscreen area into the standard screen u2013 where the programmer can attach his subscreen of his own program with the new fields.
    A function group under which the new subscreen has to be created with the new fields.
    Function exits to synchronize the PBO and PAI of the standard SAP program with the PBO and PAI of the subscreen u2013 so that data can flow back and forth between the standard SAP program and the program written by the developer for the subscreen. These function modules also exist in the same function group under which the subscreen will have to be developed.
    Finally, a linkage has to be done between the subscreen area of standard SAP screen with the custom subscreen constructed by the developer.
    Typically, SAP provides an enhancement in which the developer can create an append structure, use the function exits to synchronize the PBO and PAI of the standard SAP program and the custom subscreen program, and make the necessary linking( as mentioned above in step 4. But, again, this is not a hard and fast rule. Linking in some case, is also done by configurations.) SAP also usually provides the name of the function group under which the subscreen has to be developed.
    Necessary guidance about implementing a screen exit development is usually available in the Documentation section of the enhancement ( can be availed by transaction SMOD).
    Pre-Requisites
    The developer to work on screen exit should have essential knowledge on the following:
    DDIC concepts, including the knowledge of append structure.
    Concept of SAP Enhancements and implementing them using Projects.
    Concept of function exits.
    Knowledge on Module Pool u2013 including subscreens, Tabstrip controls etc.
    Steps
    Guidelines
    So, a developer can follow the guidelines mentioned below to implement a screen exit to a standard SAP transaction, as and when required:
    Find out the Required Enhancements
    Go to SMOD. Press F4 in the Enhancement field. In the next popup window, click pushbutton u2018SAP Applicationsu2019. A list will appear that contains information on all the enhancements, categorized under functional areas. Developer must search for the enhancements relevant to his functional area of interest u2013 for e.g., Purchasing, Asset Accounting, etc.
    Note down the enhancements. Then, come to the initial screen of SMOD and view the documentation of each enhancement to find out which one is required for your development.
    Utilize the Enhancement in a Project
    After you have found one, do as directed in the documentation. Generally, the steps are as follows:
    Create a project using CMOD including your enhancement.
    Create the append structure with new fields.
    Go to the desired function group and create a subscreen with the new fields. Write PBO and PAI for the subscreen, if required.
    Use the function exits in the enhancement to link the PBO and PAI of the subscreen with that of the main SAP program supporting the SAP transaction.
    Maintain necessary linkage between the subscreen area of standard SAP program with the custom subscreen developed along with the custom program name. This can be done in the project (developed by CMOD including the enhancement) or outside as a part of configuration.
    Activate the project.
    Test to ensure that required functionality are met.
    Case Study 1
    Add three new custom fields for Asset master and maintain information for them
    Requirement
    Three fields in the legacy system have to be maintained in Asset master. These fields are:
    Original Asset number u2013 20 characters
    Location 2 u2013 15 Characters.
    Model no u2013 20 characters
    Location 2 should start with u2018Lu2019.
    Pre-Analysis
    Finding out the Enhancement
    As described above, the enhancement is determined. It was found, that enhancement AIST0002 will serve the purpose. It contains the following components (can be viewed by transaction SMOD):
    Exit Type Description EXIT_SAPL1022_001 Function Exit Check of User-Defined Fields when Using Create and Change BAPI EXIT_SAPLAIST_002 Function Exit Transfer Data for User Subscreens in PBO. EXIT_SAPLAIST_003 Function Exit Transfer of User-Defined Fields to SAP Master Data Transactions CI_ANLU Customizing Include Include structure to add new fields
    Studying the Function Exits
    The function module level documentation for the function exits are then viewed from transaction SE37. The documentation clearly laid out for the purpose for their use:
    EXIT_SAPLAIST_002
    Function module Level Documentation
    This function module is called by asset master data maintenance at the start of the dialog. (When changing, it is called after reading of the data from the database; when creating it is called after the transfer of the default values from the asset class and reference asset.) The purpose of the function module is to enable this function group to recognize the master data. For interpreting or controlling master data fields that are important for user fields, it is possible to transfer to global variables at this point, so that they can be recognized when the user subscreens are processed.
    Import Parameters
    Understanding
    This function module is called at the PBO to pass the information retrieved from the database to pass them to the custom subscreen and its underlying program. Import parameter : I_ANLU will be populated with the values for user-defined fields which will be passed to the subscreen program. So, there must be some sort of variable assignment from I_ANLU.
    EXIT_SAPLAIST_003
    Function module Documentation: This function module is called by SAP asset master data maintenance after the screens are processed, but before saving. The purpose of the function module is to transfer fields entered on user sub-screens of SAP asset data maintenance to the database for updating. The export parameter for this function module is:
    Understanding
    This function module will be used to transfer the user entered data in the subscreen fields to the main SAP program, which will then be saved into the database.
    Studying the Documentation of the Enhancement
    The enhancement documentation (as is viewed from the initial screen of SMOD] also supports the idea. Moreover, it informs that we need to develop a subscreen under function group XAIS. This is the function group under which the two function exit modules also exist. So, if the custom subscreen refers to the global data of the function group XAIS, then those values will also be available to these function exits as well.
    Going to SE80 and viewing the function group XAIS helps us to inform that there are three DDIC tables declared for it:
    Deciding the Final course of Action
    After making all the investigations, the final course of action was determined.
    SrlNo Step Justification
    A project has to be created using transaction CMOD where the enhancement AIST0002 will be included.
    Customizing include CI_ANLU has to be created with the custom fields demanded When CI_ANLU will be developed, the custom fields will get appended to the database table ANLU. Also, these fields will be used to create screen fields in the new subscreen.
    A custom subscreen, say, 9000 will be developed under function group XAIS. The screen group for the screen will be u2018CUSTu2019 (or any name). The three custom fields added to table ANLU (by creating CI_ANLU) will be used to create new fields in the screen.
    In the PAI of the subscreen, validation for Location to start with u2018Lu2019 will be added. The subscreen with three new fields has to be developed so that it can be attached to a subscreen area of the asset master screens.
    In the custom include of the function exit module u2018EXIT_SAPLAIST_002u2019, the following code will be written:-
    ANLU = I_ANLU. I_ANLU is the import parameter of this FM. The value is assigned to the global variable ANLU, referring which the three new subscreen fields are developed. So, data retrieved from database table ANLU will be passed to this FM as I_ANLU by the standard SAP main program. The value will be taken and passed to the global variable of the function group XAIS, so that the three custom fields (referring to ANLU of XAIS) get populated.
    In the custom include of the function exit module u2018EXIT_SAPLAIST_003u2019, the following code will be written:-
    E_ANLU = ANLU. The changed values in the subscreen fields exist in global variable ANLU for the function group XAIS. This function exit module will pass the data back to the SAP main program as E_ANLU.
    Proper linkage/configuration has to be done so that the new subscreens get linked to the appropriate subscreen area of the Asset master screen. This has to be done u2013 otherwise, the new custom subscreen will not be displayed in the Asset master screens.
    Development
    Creating a Project to include the enhancement
    Go to transaction CMOD and create a project.
    Enter a description for the project. Then, click on the pushbutton u2018Enhancement Assignmentsu2019 in the Application Toolbar.
    Enter the name of the enhancement and Save.
    Go to u2018Componentsu2019.
    Creating Custom Include for ANLU
    The screen shown below will appear, showing all the enhancement components under the assignment AIST0002. Double-click on the name of the Include Structure to create it.
    Create the include structure with three new fields, as required. Then, save and activate it.
    Develop the subscreen and the program
    Go to transaction SE80. For the function group XAIS, create a new subscreen 9000.
    Create it as subscreen.
    Then, go to the Layout of the screen and create three new fields from Database table ANLU.
    Drag the fields in the screen body and place them.
    Then, save and activate the screen and come back to screen flow editor.
    Create the PAI module to add validation for field u201CLocation 2u201D, as required .
    Activate the whole function group and come out.
    Write code in the Function Exits to synchronize the programs
    Now, code has to be written in the function modules EXIT_SAPLAIST_002 and EXIT_SAPLAIST_003 so that data flows to and fro between the main SAP program and custom subscreen program. For that, go back to transaction CMOD and change the function exits.
    Write code in the function module EXIT_SAPLAIST_002 called once at the beginning of the transaction:
    Write code in EXIT_SAPLAIST_003 to pass the data from the subscreen to SAP main program.
    Then, activate everything u2013 the whole project and come out.
    Complete the configuration to link the subscreen
    The development portion is complete. Now, linking of the subscreen has to be done with the subscreen area of the main program. In most of the cases, this linking can be done in the enhancement itself. But, here, requirement is a bit different. It is done by configuration using SPRO.
    Assets are created under Asset class. And for each asset class, there is a layout assigned to it. For a layout, there are multiple tab pages assigned to it. And, for each tab page, there are multiple screen groups/field groups assigned.
    Here, the requirement is to create these three custom fields in the tab page u2018Generalu2019 of asset master screen ( AS01/AS02/AS03/AS91).
    Determine the Layout
    To achieve this, first of all, we need to find out which layout is assigned to asset class 1000.For that, go to transaction AOLK( information has to be obtained from functional consultant).Select the Asset Class u20181000u2019 and click on folder u2018General Assignment of Layoutu2019.
    Here, for Asset class 1000, for all the user groups, tab layout SAP is assigned. Since layout u2018SAPu2019 cannot be changed, it has to be copied and manipulated to include our screen group. Later, the new layout has to be assigned over here.
    Create new tab layout
    Go to transaction AOLA. Copy the tab layout u2018SAPu2019 to create another layout, say, YSUB.
    System will copy all the settings and will inform you about that.
    Select your newly created layout and double-click on the folder u2018Tab page titlesu2019.
    You want to put your custom fields in the tab page u201CGeneralu201D. So, select this tab page entry and double-click on the folder "Position of Groups".
    Here, all the field groups currently residing in the tab-page u201CGeneralu201D are shown. Add an entry for your newly created fields.
    Select the group box from the list. An entry will come with u201CUu201D padded with the custom subscreen prepared by you.
    Then, save and come out.
    Assign the new Layout to Asset Class
    Now, go to tcode AOLK and assign tab layout YSUB for asset class 1000.
    Save and come out.
    Test the Exit
    Everything is over. Now, go to transaction code AS01/02/03 or AS91 to deal with an asset of asset class 1000. You will see your new fields added to the screen. Add values to themu2026save. Then, enter into the tcodes again to see whether the values entered by you are being displayed or not.
    I hope you read it all
    Thanks and Regards
    Santosh K.
