Dropdown list value not passed to program.

I have added a dropdown control in a screen. In the runtime system populating the drop down values. However, if the users selects the a value from the dropdown, the value is not getting passed to the screen element.

Please provide your inputs.

Thank you in advance.

Raja,

You have to use below FM to get the values you selected.

DATA : dynnum TYPE sy-dynnr,

dynpro_values TYPE TABLE OF dynpread,

field_value LIKE LINE OF dynpro_values.

DATA: dynfields TYPE TABLE OF dynpread WITH HEADER LINE.

PARAMETERS :p_mngrp LIKE viqmsm-mngrp AS LISTBOX VISIBLE LENGTH 9,

CLEAR : field_value, dynpro_values ,i_qpcd.

REFRESH : dynpro_values ,i_qpcd.

field_value-fieldname = 'P_MNGRP'.

APPEND field_value TO dynpro_values.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

dyname = sy-cprog

dynumb = sy-dynnr

translate_to_upper = 'X'

TABLES

dynpfields = dynpro_values.

READ TABLE dynpro_values INDEX 1 INTO field_value.

IF NOT field_value-fieldvalue IS INITIAL.

IF sy-subrc = 0 AND field_value-fieldvalue = 1.

field_value-fieldvalue = 'I&CSCR'.

ELSEIF sy-subrc = 0 AND field_value-fieldvalue = 2.

field_value-fieldvalue = 'I&CSCF'.

ENDIF.

p_mngrp = field_value-fieldvalue.

Don't forget to reward if useful......

Hi Raja,

For me this code is working fine. I have written the code in PBO of screen.

MODULE init_screen OUTPUT.

CLEAR wa_itab.

SELECT matnr

into table it_matnr

from mara

up to 3 rows.

LOOP AT it_matnr

into wa_matnr.

z_key = z_key + 1.

wa_itab-key = z_key.

wa_itab-text = wa_matnr-matnr.

APPEND wa_itab TO it_itab.

ENDLOOP.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = 'ZMATERIAL' " Field where i have created the list box

values = it_itab

EXCEPTIONS

id_illegal_name = 1

OTHERS = 2.

ENDMODULE. " init_screen OUTPUT

Usually in PAI the we can get the selected value.

Pls check the name of the listbox and the name of correponding text box which you placed for the description. IF it is same, try to change any one of them.Also check the LISTBOX name is declared in the TOP include.
