Hiding columns in table control

Hi Experts,
I have requirement to hide certain columns in table control. I have tried my best to use SCREEN structure with ACTIVE, INVISIBLE, INPUT, OUTPUT options, but not working properly.
The table control has nearly 10 columns with DATE as the first one. Once the screen appears after executing program, the second and third columns should be hidden and when double clicked on any date value from the basic list, the hidden columns should be visible with its values in the next level.
I am not able to hide columns in table control. By the way, suggest me options for double clicking in table control too.
Thanks.

Hi,
The value of sy-ucomm when user double clicks is /CS
To get the details of field name and value use:-
GET CURSOR FIELD g_cs_field VALUE g_cs_value.
Now you can code in PAI to display those two columns initially hidden by the user:-
CASE sy-ucomm.
WHEN '/CS'.
    IF g_cs_field = '<field1_name>'.
      LOOP AT SCREEN.
        IF screen-group1 = 'ABC'.
          screen-invisible = 0. "display control
          screen-active = 1.
        ENDIF.
        MODIFY SCREEN.
      ENDLOOP.
    ENDIF.
ENDCASE.
Remember that in PBO of screen you have written a code to hide these same columns initially, so make sure that the code is not executed when user double clicks to display those columns.
Try this code for hidding the columns in table control initially.
MODULE status_8001.
LOOP AT SCREEN.
    IF screen-group1 = 'ABC'.
      screen-invisible = 1. "hide control
      screen-active = 0.
    ENDIF.
    MODIFY SCREEN.
ENDLOOP.
ENDMODULE.
Hope this helps you.

Reg:How to delete the column in table control also from database table.

Hi Experts,
Once again thank u all for giving the responses.
one more doubt is how to delete the columns of table control and also the record shold delete from ztable.
With Regards,
Saroja.P.

Hi,
If you want to delete the rows in the table control and simultaneously delete it from the database table, then you can implement a 'DELETE' functionality specific to your table control. Have a MARK field (you will find that in the screen attributes of the table control -> give a name for the MARK field, you will find an additional MARK column at the beginning of your table control). You can check whatever rows you want to delete from the table control, call the delete module.
"This portion of code inside the LOOP...ENDLOOP.
IF sy-ucomm eq 'F_DELETE'.
gt_itab2-check = mark. " Store the MARK field status into your internal table's correspoding field 'check'
MODIFY gt_itab INDEX tabcontrol-current_line.
ENDIF.
iF sy-ucomm eq 'DELETE1'.
DELETE gt_itab WHERE check eq 'X'. "Your internal table does not have rows that you want to delete
ENDIF.
Now you can modify your database table using the MODIFY statement.
MODIFY ZDB FROM TABLE gt_itab.

Let your table control name in Screen painter be TC1.
READ TABLE TC1-COLS INTO WA_COLS (some wok area)
             WITH KEY SELECTED = 'X'.
        IF SY-SUBRC = 0.
          CLEAR: W_DUMMY, W_COL_NAME.
          SPLIT WA_COLS-SCREEN-NAME AT '-' INTO W_DUMMY
                                               W_COL_NAME.

How to add a column in table control

Hi ,
Can any one tell me how to add a column in table control? My requirement is to add two columns ( custom fields ) into table control ( It is a standard program). I have added the column in the table and also in the table control. But when I am running the standard program, The newly added column is not there. But I have added in the perticular screen. Change is not reflected.
Can anyone help me on this please.
Thanks in advance.
Regards,
Lakshmi.

Hi,
Ensure the following :
1. After adjusting the database, you`ll have to use the database utility and activate the table.
2. If you have changed the standard screen, in tcode se80 -- right click on the program and click activate all. This activates all objects related to that program.
Now execute the program.

Push button in one of the columns of Table Control

Hi,
I have a requirement, where i have to display a push button in one of the columns of table control for long text. When user clicks on the control, a pop up has to be appeared in which user should be able to enter some meaning ful description and save it. please suggest me how to do this requirement.
Best Regards,
Phani Kumar. S

Hai,
You can drag n drop a button to the required column in the table control and give the required parameters like ok_code , name etc.
You can now place a text field as the heading of the column.
Now when the user clicks the the button in a row, read the corresponding line in which he has clicked.For that u can use
get cursor lines wrk_line.
now u'll get the data in that row using
Read table it_tab into wa_tab index wrk_line.
now u can call the text editor (using FM's READ_TEXT ,EDIT_TEXT and CREATE_TEXT in which the user can enter the meaningful description and save it.
When u save the text entered save it with a key part of the row that was read earlier(keep it as the text name).
So now if u need to get the description which was entered earlier u can easily read the text (using READ_TEXT ).
I hope this will be helpful for u .
Thanks

HI
Create three attribute in the node which is bound to the table as data source.
say pro1, pro2, and pro3 of type wdy_boolean.
now bind the enabled property of first four column editors to pro1, last 4 to pro2, and pro3 to first 2 and last 2.
then go to the eventhandler of the dropdown 's on select event and write the code to update the values of these attribute
according to the selected value.
here is the sample code.
DATA lo_nd TYPE REF TO if_wd_context_node.
    DATA lo_el TYPE REF TO if_wd_context_element.
        DATA lv_VAL LIKE ls_dealer1-name.
    lo_nd = wd_context->get_child_node( name = 'DEALER1').
lo_el = lo_nd->get_element( ).
    lo_el->get_attribute(
      EXPORTING
        name = `NAME`
      IMPORTING
        value = lv_VAL ).
     DATA PR1 TYPE WDY_BOOLEAN.
     DATA PR2 TYPE WDY_BOOLEAN.
     DATA PR3 TYPE WDY_BOOLEAN.
PR1 = ABAP_TRUE.
PR2 = ABAP_TRUE.
PR3 = ABAP_TRUE.
IF LV_VAL EQ 'A'.
PR1 = ABAP_FALSE.
PR2 = ABAP_TRUE.
PR3 = ABAP_TRUE.
   ELSEIF LV_VAL EQ 'B'.
PR1 = ABAP_TRUE.
PR2 = ABAP_FALSE.
PR3 = ABAP_TRUE.
ELSEIF LV_VAL EQ 'C'.
PR1 = ABAP_TRUE.
PR2 = ABAP_TRUE.
PR3 = ABAP_FALSE.
ENDIF.
   LO_EL->SET_ATTRIBUTE(
   NAME = 'PRO1'
   VALUE = PR1
   LO_EL->SET_ATTRIBUTE(
   NAME = 'PRO2'
   VALUE = PR2
   LO_EL->SET_ATTRIBUTE(

Default value for a column in Table Control

Hi friends, can i set dinamcally a default value for a column in table control?, this column is check type. This default value must appear in empty rows,
thanks

ADD A MODULE AS Module yyyy In ur PAI.
as
In PAI.
LOOP at itab.
Module YYYY
ENDLOOP.
Module YYYY.
LOOP AT SCREEN.
    IF SCREEN-NAME = 'ITAB-VAL.
      ITAB-VAL = 'XXXXXXXX'        "(DEFAULT VALUE)
      SCREEN-INPUT = 0.
      MODIFY SCREEN.
    ENDIF.
ENDLOOP.
End module.
*note
make this event work only if the previous column is filled okay.
the display will be in display mode on the screen as screen-input = 0.
see that in the table control u can get the table field for all the rows even though you are processing on some fields .
so what u do is make that particular filed masked(no i/p field and populate the field that will be better instead of populating all the columns okay.
hope this helps you out ,

vijay.

When you select a value, PBO as well as PAI gets triggered. When PAI gets triggered, your query gets executed which gives sy-subrc <> 0 and due to this it might not filling the data selected..

Push button column in table control

Hi,
I have to add a few push button columns into table control. This columns has to be placed between fields of DDic table. How to do this? Shall I create new DDic structure with all the needed fields from DDic table and add also fields for push button columns? Which data element shal I use in this case for push button field? Or is the better solution to add DDic table fields one by one and then using drag and drop technique to add push button column behind it?
Thanks.

Hi ,
Your Last option is better first add columns into DDIC table then Drag and
Drop it on table control .
That will better definitely.................................
if useful rewards the point..............
Thanks .

How to delete columns in table control (tab Services) for transaction ME51

Hi, gurus!
We're facing this problem in our upgrade: we have a batch input (ME51) in order to create purchase requisitions, but we get an error with the dynpro data (program: SAPMM06B, dynpro: 0102).
We are sure we populate all the required fields in that screen.
The only possible reason we find for that error is the fact that we have two new entries in table control (in tab services=> Current settings there are 67 fixed columns)
We had to add in table T162V (which previously had only 65 columns for each variant): ESLL-SRVMAPKEY y ESLL-EXTERNALID, as described on note 1382685, so table control and table T162V could have same number of fields.
We guess we could solve the batch input error deleting those fields in both table control and T162V, but don't know how.
We really would appreciate any clue.
Thanks in advance.
Best regards,
J. Madariaga

It's an own batch input.
The error is: "Batch input information for dynpro SAPMM06B 0102 does not exist", but the fields in that screen are alright.
And that batch input works fine in another client with same patch level, but without fields ESLL-SRVMAPKEY and ESLL-EXTERNALID in table T162V, so I guess that could be the problem (not sure about it, of course).

J Madariaga

How to delete columns in table control

hi
1) I have creted a table control with five columns
now i want to delted the tow of the five coluent pls let me know how to delete it
1) also i am useing a module pool programming (code if needed i will paste)
in that the requirment is to select data from a ztable and aloow user to enter new ship to data only whne the corresponding records exists in kna1 table
and to populate the name1 value automatically from table kna1 whne user enters ship to number
pls suggest
regards
Arora

Hello,
Requirement 1
i believe you need to delete a row from the control table based on the user input...
if thats the case then definitely in the control table the multiple line selection will be activated .
in PAI of the control table screen...
if user has clicked delete.
loop at control table records..
if the selection code for the line is 'X'.
Delete from the internal table.
endif.
endloop.
endif.
Requirement 2..
i will give an outline on the checks
a)first let the user enter the data...in the PAI of the screen...write the code to do the checking....if your requirement is not satisfied provide a warning/error message or delete the record and give a message stating the reason for deletion...
in PAI.
for a control table...
loop at the table records
select from table and check if user record is O.K
if not delete the record and give message
endif.
endloop.
b)similarly inside the PBO write code to fetch the name1 from Kna1 table for the ship to number if that ship to number is not empty
in PBO of that screen
if ship_to is not initial.
select text for ship_to number to the display field
else.
clear the display field
endif.
reward if the suggestions were useful
Regards
