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.
PROCESS BEFORE OUTPUT.
LOOP WITH CONTROL TCREG.
MODULE READ_ITAB_REG.
ENDLOOP.
PROCESS AFTER INPUT.
LOOP WITH CONTROL TCREG.
CHAIN.
FIELD: ITAB_REG-REG,
ITAB_REG-DESC.
MODULE MODIFY_ITAB_REG
ON CHAIN-REQUEST.
ENDCHAIN.
ENDLOOP.
MODULE READ_ITAB_REG OUTPUT.
READ TABLE ITAB_REG INDEX TCREG-CURRENT_LINE.
IF SY-SUBRC EQ 0.

ELSE.
EXIT FROM STEP-LOOP.
ENDIF.
ENDMODULE.
MODULE MODIFY_ITAB_REG INPUT.
MOVE-CORRESPONDING TCREG TO ITAB_REG.
MODIFY ITAB_REG INDEX
TCREG-CURRENT_LINE.
ENDMODULE.
Updating the internal table
Method 1
PROCESS AFTER INPUT.
LOOP AT ITAB_REG.
CHAIN.
FIELD: ITAB_REG-REG,
ITAB_REG-DESC.
MODULE MODIFY_ITAB_REG ON CHAIN-REQUEST.
ENDCHAIN.
ENDLOOP.
MODULE MODIFY_ITAB_REG INPUT.
ITAB_REG-MARK = u2018Xu2019.
MODIFY ITAB_REG INDEX TCREG-CURRENT_LINE.
ENDMODULE.
Method 2

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
ENDLOOP.
PROCESS AFTER INPUT.
MODULE user_command_8002. "for user command(back and exit)
LOOP WITH CONTROL po_tab.
    MODULE modify_data. "to modify data from table control into table control
ENDLOOP.
MODULE delete. "to delete the selected records
In PBO,
*&      Module STATUS_8002 OUTPUT
MODULE status_8002 OUTPUT.
SET pf-status 'ZAB_PFSTA'. " pf-status
DATA : line_count TYPE i.
DESCIRBE TABLE it_ekpo

" to make table control scrollable
ENDMODULE.                 " STATUS_8002 OUTPUT
*&      Module PASS_DATA OUTPUT
MODULE pass_data OUTPUT.
READ TABLE it_ekpo into wa_ekpo INDEX po_tab-current_line.
ENDMODULE.                 " PASS_DATA OUTPUT

      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
        MOVE-CORRESPONDING WA_EKPO TO WA_EKPO1. "append selected records to another
        "work area and append to another internal table to delete
        APPEND WA_EKPO1 TO IT_EKPO1.
        DELETE IT_EKPO. "delete the selected records from initial internal table
        " 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.
          MESSAGE S007. "success message (records deleted)
        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.
Thanks & Regards,
Tarun Gambhir

Problems with retrieving data from tables with 240 and more records

Hi,
I've been connecting to Oracle 11g Server (not sure exact version) using Oracle 10.1.0 Client and O10 Oracle 10g driver. Everything was ok.
I installed Oracle 11.2.0 Client and I started to have problems with retrieving data from tables.
First I used the same connection string, driver and so on (O10 Oracle 10g) then I tried ORA Oracle but with no luck. The result is like this:
I'm able to connect to database. I'm able to retrieve data but from small tables (e.g. with 110 records it works perfectly using both O10 and ORA drivers). When I try to retrieve data from tables with like 240 and more records retrieval simply hangs (nothing happens at all - no error, no timeout). Application seems to hang forever.
I'm using Powerbuilder to connect to Database (either PB10.5 using O10 driver or PB12 using ORA driver). I used DBTrace, so I see that query hangs on the first FETCH.
So for the retrievals that hang I have something like:
(3260008): BIND SELECT OUTPUT BUFFER (DataWindow):(DBI_SELBIND) (0.186 MS / 18978.709 MS)
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=0
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=1
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=0
(3260008): EXECUTE:(DBI_DW_EXECUTE) (192.982 MS / 19171.691 MS)
(3260008): FETCH NEXT:(DBI_FETCHNEXT)
and this is the last line,
while for retrievals that end, I have FETCH producing time, data in buffer and moving to the next Fetch until all data is retrieved
On the side note, I have no problems with retrieving data either by SQL Developer or DbVisualizer.
Problems started when I installed 11.2.0 Client. Even if I want to use 10.0.1 Client, the same problem occurs. So I guess something from 11.2.0 overrides 10.0.1 settings.
I will appreciate any comments/hints/help.
Thank you very much.

Installing 11g client changed something that even using old 10g client (which I still have installed) fails to work. The same problem occur no matter I'm using 10g or 11g client now. Powerbuilder hangs on retrieving tables with more than like 240 records.
