How to clear data from Table-Control

Hi all,
I am working on table control. I have some data on the table control.
When I press the 'Cancel' button, I require that the table-control should be cleared.
I tried using REFRESH CONTROL TC01 USING SCREEN 1001. But, the data doesn't get cleared.
Please advise.
Regards,
Saurabh Buksh.

hi

      save_ok TYPE sy-ucomm.
DATA: itab TYPE TABLE OF demo_conn.
      TABLES demo_conn.
SELECT * FROM spfli INTO CORRESPONDING FIELDS OF TABLE itab.
LOOP AT flights-cols INTO cols WHERE index GT 2.
  cols-screen-input = '0'.
  MODIFY flights-cols FROM cols INDEX sy-tabix.
ENDLOOP.
CALL SCREEN 100.
MODULE status_0100 OUTPUT.
  SET PF-STATUS 'SCREEN_100'.
  DESCRIBE TABLE itab LINES lines.
  flights-lines = lines.
ENDMODULE.
MODULE cancel INPUT.
  LEAVE PROGRAM.
ENDMODULE.
MODULE read_table_control INPUT.
  MODIFY itab FROM demo_conn INDEX flights-current_line.
ENDMODULE.
MODULE user_command_0100 INPUT.
  save_ok = ok_code.
  CLEAR ok_code.
  CASE save_ok.
    WHEN 'TOGGLE'.
      LOOP AT flights-cols INTO cols WHERE index GT 2.
        IF  cols-screen-input = '0'.
          cols-screen-input = '1'.
        ELSEIF  cols-screen-input = '1'.
          cols-screen-input = '0'.
        ENDIF.
        MODIFY flights-cols FROM cols INDEX sy-tabix.
      ENDLOOP.
    WHEN 'SORT_UP'.
      READ TABLE flights-cols INTO cols WITH KEY selected = 'X'.
      IF sy-subrc = 0.
        SORT itab STABLE BY (cols-screen-name+10) ASCENDING.
        cols-selected = ' '.

  • How to retrieve data from Table Control

    Hi,
    I am a Beginner to ABAP. I want to know how to fetch the selected rows from Screen table control.
    Here is my scenario:
    I am having one table control with selection field. Once i select some rows means the selected rows are going to be stored in one Internal Table.
    If any body knows the thing means please reply me the logic as well as giving me some code sample.
    Thankyou.

    Hi Mithun,
    Try to implement this code in your requirement.
    There will be some button on your screen and after selecting some or all the records from the table control you must be pressing some button for collecting the selected rows from the table control too your internal table.
    Put Fcode of that button in WHEN condition in this CASE.
    CONSTANTS: kc_sel_flag TYPE char01    VALUE 'X'.
      CASE sy-ucomm.
        WHEN kc_sel.
          PERFORM f_sel_desel USING kc_sel_flag.
      ENDCASE.
    FORM f_sel_desel
         USING    p_sel_desel TYPE c.
    Set the value
      wa_cond_type-z_sel = p_sel_desel.
    Update the Itab.
      MODIFY it_cond_type
             FROM wa_cond_type
             TRANSPORTING z_sel
             WHERE mandt EQ sy-mandt. "Where cond is only to specify all
    ENDFORM.                    " f_sel_desel
    After that all the selected records will be having 'X' in the internal table.

    Hi Darshan,
       Here is a detailed description of how to update data in table controll.
      Updating data in table control
    The ABAP language provides two mechanisms for loading the table control with data from the internal table and then storing the altered rows of the table control back to the internal table.
    Method 1: Read the internal table into the Table Control in the screenu2019s flow logic.  Used when the names of the Table Control fields are based on fields of the internal table.
    Method 2: Read the internal table into the Table Control in the module pool code. Used when the names of the Table Control fields are based on fields of the database table.
    Method 1 (table control fields = itab fields)
    In the flow logic we can read an internal table using the LOOP statement. Define the reference to the relevant able control by specifying WITH CONTROL <ctrl>
    Determine which table entry is to be read by specifying CURSOR <ctrl>-CURRENT_LINE.
    After the read operation the field contents are placed in the header line of the internal table. If the fields in the table control have the same name as the internal they will be filled automatically. Otherwise we need to write a module to transfer the internal table fields to the screen fields.
    We must reflect any changes the user makes to the fields of the table control in the internal table otherwise they will not appear when the screen is redisplayed after PBO processing, (eg, after the user presses Enter or scrolls) However, this processing should be performed only if changes have actually been made to the screen fields of the table control (hence the use of the ON REQUEST)
    PROCESS BEFORE OUTPUT.
    LOOP AT ITAB_REG WITH CONTROL TCREG
    CURSOR TCREG-CURRENT_LINE.
    ENDLOOP.
    PROCESS AFTER INPUT.
    LOOP AT ITAB_REG.
    MODULE MODIFY_ITAB_REG.
    ENDLOOP.
    MODULE MODIFY_ITAB_REG INPUT.
    MODIFY ITAB_REG INDEX TCREG-CURRENT_LINE.
    ENDMODULE.
    Method 2 (table control fields = dict. fields)
    If using a LOOP statement without an internal table in the flow logic, we must read the data in a PBO module which is called each time the loop is processed.
    Since, in this case, the system cannot determine the number of internal table entries itself, we must use the EXIT FROM STEP-LOOP statement to ensure that no blank lines are displayed in the table control if there are no more corresponding entries in the internal table.

  • How to delete data in table control

    Hi,
    I am doing module pool programming. After the user enters the data in table control after saving the data. if the user wants to  remove the line item the line item shd be removed from the screen and data base.
    Please Give me vaulable Suggestions
    Regards

    Hi,
    Screen 8002 (with table control) --> select records --> press delete button --> delete selected records
    Now you wan to delete those records selected by the user at runtime when DELETE button is clicked.
    Take another internal table and work area same as the initial internal table and work area used in screen 8002 which is to be used to delete the selected data.
    Take the names of the input/output fields as work_area-field_name and select column in table control as work_area-flag.
    Also take a flag field of size 1 datatype character as the last field in the internal table and work area while declaration.
    You must have passed a code in PBO of the screen for reading internal table into the table control.
    So it reads the internal table into the table control whenever you perform any action on use command.
    All you need to do is to write a code to modify the internal table form the table control while performing any user action.
    Remember to change the LINE SEL option in attributes of table control as MULTIPLE.
    At screen logic,
    PROCESS BEFORE OUTPUT.
      MODULE status_8002. "for pf-status
      LOOP WITH CONTROL po_tab. "po_tab is table control
        MODULE pass_data. "to pass data into table control from internal table

          CLEAR WA_EKPO1.
          CLEAR WA_EKPO.
          REFRESH IT_EKPO1.
          LOOP AT IT_EKPO INTO WA_EKPO WHERE FLAG = 'X'.
            DATA : J TYPE I.
            CLEAR J.
            J = SY-TABIX. "assign index value if a record is selected

            " to reflect the changes on the table control
          ENDLOOP.
          IF J = 0.
            MESSAGE I006. "if no record selected
          ELSE. "if some records are selected
            DELETE ZEKPO FROM TABLE IT_EKPO1. "delete from database table
            COMMIT WORK.
            IF SY-SUBRC = 0.

            ENDIF.
          ENDIF.
      ENDCASE.
    ENDMODULE.                 " DELETE  INPUT
    Now at PAI, you have delete records and these changes are reflected back to the internal table.
    Now when PBO is executed it will again read the initial internal table and will not show the deleted records.
    Hope this solves your problem.

    Hi Viju,
    In PAI do something like this
    LOOP AT itab.
        MODULE mod_table_control.
    ENDLOOP.
    MODULE user_command_0100.
    at module mod_table_control put this
    MODULE mod_table_control INPUT.
      MODIFY itab FROM demo_conn INDEX flights-current_line.
      if sy-subrc ne 0.
           insert itab.
      endif.
    ENDMODULE.
    for saving you can create at custom gui status with a save button, and at MODULE user_command_0100 save the data.

  • How to populate data from table into datagrid in form

    hi there. may i know how to populate data from a table into a datagrid? i have created a datagrid in a form using OLE's microsoft datagrid. i'm having problem to populate data from table into the grid. can i know how to do that? thanks

    Not exactly. I want to enter input from form and the user can have all options to choose i.e. HIGH, MEDIUM or so on.
    Suppose, you have option to select HIGH, MEDIUM or LOW and you can see all these options together. You select LOW and when you save, it is saves in the table as a value. So when you view the table again, it will show LOW as active and HIGH and MEDIUM are null.

  • How to read data from table GLFUNCA quickly?

    Hello everybody!
         Recently,my colleague has programmed a report about reading data from table GLFUNCA,and its speed is very slowly and exceeded limited time sometimes .
    Excuse me?
    how to use INDEX and VIEW TO accelerate it?
    pls supply my helpful solutions.
    Thanks!
    Best wishes!

    Hi,
    Please check your SELECT statement to find out what are the columns being used in the WHERE clause. Then go to SE11 and find out if there are indexes on those columns.
    If Indexes don't exist then you can create indexes on those columns, which might improve the performance.
    However, there might be other areas also, where the performance can be improved. Do a run time analysis / trace and figure which part of the program is taking maximum time.
    Regards,

  • How to Insert data from Table A to Table B

    Hi,
    I have to insert data from Table A into Table B.
    Table A is having 100 records and table B is having 10000 records.
    Condition is if data in Table A is not in table B then I have to insert into Table B or else I have to skip that.
    Can anyone help me with sample code.
    Thanks in advance and points are awarded for usefull answers.
    Thanks,
    Kumar.

    Hello Kumar
    Assuming that tables A and B have the same structure you can use the same logic as change documents are prepared. Assuming both of your itabs are of structure struc_a. Then define the following type:
    TYPES: BEGIN OF ty_s_itab_di. 
    INCLUDE TYPE struc_a.
    TYPES: CHIND  TYPE bu_chind.
    TYPES: END OF ty_s_itab_di.
    TYPES: ty_t_itab_di  TYPE STANDARD TABLE OF ty_s_itab_di                     
    WITH DEFAULT KEY.
    DATA:    gt_itab_old  TYPE ty_t_itab_di,
    gt_itab_new TYPE ty_t_itab_di.
    Fill itabs gt_Itab_old with the corresponding data of itab1 and gt_itab_new with the corresponding data of itab2.
    Very important: sort you itabs either by all key fields or by all fields.
    Call function <b>CHANGEDOCUMENT_PREPARE_TABLES</b> with the following parameters:
    - CHECK_INDICATOR = ' '
    - TABLE_NEW = gt_Itab_new
    - TABLE_OLD = gt_itab_old
    The function module will remove identical lines from both itabs. New entries in gt_itab_New will have CHIND = 'I' and deleted entries in gt_itab_old will have CHIND = 'D'. Modified entries are indicated by CHIND = 'U'.
    Read the documentation of the function module and play around with it. You will see that this a quite easy yet powerful approach for comparing itabs.
    Regards

  • How to display data in Table control?

    Hi Experts,
    Can anyone please explain me how to display the data from two different tables(those two table is related with 1 field) into a single table control?
    For Example: T1 has fields (F1,F2) and
                         T2 has fields (F3,F4) --> here F3 is foreign key for F1
    I need to display the data F1,F2,F3,F4 into the table control.
    Can anyone explain me?
    Thanks in Advance,
    Regards,
    Raghu

    Hi,
    If F3 is foreign key for F1, then both fields will have same values.  Then why do you need to display both F1 and F3?  Either one of them is enough.  Try the following code.
    types: begin of t_table,
                 F1 type T1-F1,
                 F2 type T1-F2,
                 F4 type T2-F4,
              end of t_table.
    data: i_table type standard table of t_table with header line.
    select F1 F2 F4 into table i_table from T1 inner join T2 on T1F1 = T2F3.
    You should create three columns in the table control with names i_table-F1, i_table-F2, i_table-F3.
    After populating the internal table, refresh the control with the following statement.
    REFRESH CONTROL <NAME> FROM SCREEN <SCREEN_NO>.
    All the above statements should be in your PBO Module.
    Regards,
    Hema

    Sorry, Declarations can be in the common include.  Select statement and refresh statement should be in PBO.
