List Box in Table control

Former Member — Thu, 19 Sep 2013 06:33:31 GMT

Hi Friends,

I have a requirement where i have to display the list box in table control for a particular field.

I am able to display the filed as list box in TC with the help of list box option in property option for the field based on the dictionary values in Screen Painter.

Table control is in edit mode.

when i select the list box and add values to the other fields in the table control and press enter values has to be updated in internal table of that table control.

BUT, Issue is that i am not able to update the values in the ITAB of table control with the selected list box. If i press enter the values gets vanished.

I tried several SCN discussion but cannot find the correct answer for the issue above.

Or else is there any other way to populate the list box in table control without using option in Screen painter property.

That is by populating list box using VRM and also issue of handling data in table control.

Please help me in this issue.

With Thanks & Regards,

Kishan Raj K

Hi kishan raj k,

Please make sure that you have modified your internal table in the PAI inside the table control loop.

Ex.

LOOP AT <itab>.

MODIFY <itab> FROM <wa> INDEX tablecontrol-current_line.

ENDLOOP.

Anoop

I tried adding modify itab in the PAI. Even so same problem exist.

I have not used the VRM methods instead generated listbox using the option in screen painter is that the problem.

Hi Ramesh i have generated the list box in the table control based on the program you have said.

In the above mentioned program which you gave they are just displaying values in TC.

In my requirement TC is in Editable mode those data in the internal Table ( used for Table Control ) has to be updated in the Custom ZTable later once internal table is filled.

Hi Kishan,

VALUE-KEY = '1'.

VALUE-TEXT = 'Name'.

APPEND VALUE TO LIST.

VALUE-KEY = '2'.

VALUE-TEXT = 'Country'.

APPEND VALUE TO LIST.

in your final table it saves as 1 or 2 not like Name or Country.

Can you share your code to find wht's your problem.

*&---------------------------------------------------------------------*

*& Module MODIFY INPUT

*&---------------------------------------------------------------------*

* text

*----------------------------------------------------------------------*

module MODIFY input.

MODIFY lt_mara FROM zsample_s_list INDEX tc1-current_line.

endmodule. " MODIFY INPUT

Below code in Screen flow.

PROCESS BEFORE OUTPUT.

MODULE status_9000.

LOOP AT lt_mara INTO ZSAMPLE_S_LIST WITH CONTROL tc1.

ENDLOOP.

Hi Ramesh, this is the output i get. But when i press enter the value vanish. Matnr in the TC contains the Custom data element where i have created domain with some fixed values and created one global structure zsample_s_list where it contains all the 4 fields. List box displays only the values present in the fixed value of that domain.

Hi Kishan,

How did you populate the listbox?

Make sure that you gave quotes when you populated the list box. This problem happens when you assign the key without quotes.

      ls_value-key = '1'.
       ls_value-text = 'Mat 1'.
       append ls_value to lt_list.
       ls_value-key = '2'.
       ls_value-text = 'Mat 2'.
       append ls_value to lt_list.

Hi krishna ,

Is the whole table control line is getting vanished or just the value you filled using the list box is getting disappeared.

Hi Susmitha,

I don't populate the list box using VRM Function Module.

Instead i used the listbox option in the property window of that particular field in Screen Painter.

Please see the below image i have rounded it with red rectangle

Hi Juneed,

Why the modify statement is not working in this case. It should be inserting new records to the internal table. Why it has not worked in this case.

Can you explain why modify is not working so.
