Search Help For a Field in Module Pool Programming

Hi,
I have a field called status in Module Pool for which i need to write a search help.
This is the piece of code i have written.
TYPES: BEGIN OF ty_status,
 stat type i,
 status type string,
 END OF ty_status.
DATA: lt_emp_status TYPE STANDARD TABLE OF ty_status,
 lw_emp_status TYPE ty_status.
REFRESH lt_emp_status.
lw_emp_status-stat = '1'.
lw_emp_status-status = 'Draft'.
APPEND lw_emp_status TO lt_emp_status.
CLEAR lw_emp_status.
lw_emp_status-stat = '2'.
lw_emp_status-status = 'Employee Review'.
APPEND lw_emp_status TO lt_emp_status.
CLEAR lw_emp_status.
REFRESH lt_emp_status.
 CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
 EXPORTING
 retfield = 'STATUS'
 value_org = 'S'
 TABLES
 value_tab = lt_emp_status
 return_tab = t_return
 EXCEPTIONS

 no_values_found = 2
 OTHERS = 3.
IF sy-subrc = 0.
 READ TABLE t_return INDEX 1.
 MOVE t_return-fieldval TO LV_EMP_status.
ENDIF.
But i am getting the following error.
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_ASSIGN_CAST_ILLEGAL_CAST', was
not caught in
procedure "F4IF_INT_TABLE_VALUE_REQUEST" "(FUNCTION)", nor was it propagated by
a RAISING clause.
Since the caller of the procedure could not have anticipated that the
exception would occur, the current program is terminated.
The reason for the exception is:
The error occurred at a statement of the form
 ASSIGN f TO <fs> CASTING.
 ASSIGN f TO <fs> CASTING TYPE t.
or
 ASSIGN f TO <fs> CASTING LIKE f1.
or
 at table statements with the addition
 ASSIGNING <fs> CASTING.
The following error causes are possible:
1. The type of field f or the target type determined by <fs>, t or f1
contains data references, object references, strings or internal tables
as components.
Could some one help me how to resolve this issue.
Thanks in advance.

Regards
Darshan MS

HI,
I want to delete the row after the display of table control. I have created push button as delete row. If I click on this push button, the selected row should get deleted.
I have written this code,
module USER_COMMAND_9000 input.
DATA OK_CODE TYPE SY-UCOMM.
OK_CODE = SY-UCOMM.
CASE OK_CODE.
     WHEN 'DELETE'.
        LOOP AT lt_source INTO ls_source WHERE mark = 'X'.
            APPEND LS_SOURCE TO LT_RESTORE.
            DELETE TABLE LT_SOURCE FROM LS_SOURCE.
            SOURCE-LINES = SOURCE-LINES - 1.
        ENDLOOP.
But I'm unable to delete the selected rows, It is getting deleted the last rows eventhough I select the other row.
So I thought of doing with respect to the field.

F4 help for a field in module pool

Hello Experts,
I need to provide f4 help on field sales office(VKBUR) in my module pool program.
I have searched forums about it. but all forum contains either doc. no or customers etc.
these field are directly available on table, so very easy to find.
But for sales office, how can i provide f4 help. there is no straight entries in tables like for this company code this sales office.
so its getting difficult for me to provide help.
so if anybody know the solution plz help, and if anyone know table where all sales offices are stored, i will be thankful.
Thanks,
Amar

Hi amar_war,
use screen painter to edit the screen layout where the field VKBUR is on. Double click the field to get the details screen. Here you can attach a search help to the field.
H_TVBUR has no more parameters, it will display a list of al sales offices with description text
H_TVBVK will also show the sales group, if VKGRP is a screen field, it will restrict the result list automatically on matching VKGRP.
H_TVKBZ has also VKORG VTWEG SPART - it will take those values from screen if filled.
If you are not satisfied with the results, you can easily create your own search help using own selection method and own search help exits if required.
Try standard search help for standard field first.
You can create a copy of VKBUR as ZVKBUR and attach search help there, you can create your own screen structure and attach the search help there - 50 ways to get your search help...

Clemens

How to assign FCT code to a field in module pool programming?

Hi All,
I have two fields on the screen. One is I/O field other is text field.
suppose i enter country code in I/O field i should get the name of country in text field. I want to assign fct code to I/O field.
But in attribute popup it's not allowing to assign fct to the field.
Please Help.
Regards,
Mohammed Quddus.

Hi, as far as I know R/3 screen I/O fields does not have onkeyup event. So you can not achieve this without hitting enter. When you have to hit enter then no need for function code. You can not assign FCT for I/O fields. You can write required logic in your PAI after entering country code.
Thanks,
Siva
