Doubts on Process on value request !

Hi,

Look at this example...

*****************************

*----

at selection-screen on value-request for s_pernr-low.

*----

perform get_values changing s_pernr-low.

*----

at selection-screen on value-request for s_pernr-high.

*----

perform get_values changing s_pernr-high.

**********

&----

*& Form get_values

&----

• text

----

• -->P_S_PERNR_LOW text

----

FORM get_values CHANGING P_S_PERNR.

refresh t_itab.

clear t_return.

select pernr from zfdmr_records into table t_itab.

delete adjacent duplicates from t_itab.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

• DDIC_STRUCTURE = ' '

RETFIELD = 'PERNR'

• PVALKEY = ' '

• STEPL = 0

• WINDOW_TITLE =

VALUE_ORG = 'S'

MULTIPLE_CHOICE = ' '

• CALLBACK_PROGRAM = ' '

• CALLBACK_FORM = ' '

VALUE_TAB = t_itab

• FIELD_TAB =

RETURN_TAB = t_return

• DYNPFLD_MAPPING =

• EXCEPTIONS

• PARAMETER_ERROR = 1

• NO_VALUES_FOUND = 2

• OTHERS = 3

.

IF SY-SUBRC <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

READ TABLE t_return INDEX 1.

p_s_pernr = t_return-fieldval.

ENDFORM. " get_values

I hope it will help you.

Thanks.

If your doubt is solved award points.

Process on value request event will be there only for screens. Not for Report selection screen. If you want to write a process on value request then see example program
