Hi,

i have a selection screen in which i have two parameters. once the user enters the value in first field f1, he goes for F4 functionality on the second field f2, where i perform some validations and display the values with in 'at selection screen on value req..'.

however, i cannot see the value entered unless i hit 'Enter' after entering the value in the first field, f1.

what should i do in order to get the value entered in the first field with in my program. kindly let me know

Make a call screen before calling second seelct option, as any change require a trigger of an event to get complete.

hello kumar,

How you can say, u dont get value of p1 using dynp_values_read ?

here is what i tested for u. It is working perfect for me.

parameters : p1 like vbak-spart,

p2 like vbak-bsark.

at selection-screen on value-request for p2.

data : t_dyn like DYNPREAD occurs 0 with header line.

t_dyn-fieldname = 'P1'.

append t_dyn.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

DYNAME = sy-repid

DYNUMB = sy-dynnr

TRANSLATE_TO_UPPER = ' '
REQUEST = ' '
PERFORM_CONVERSION_EXITS = ' '
PERFORM_INPUT_CONVERSION = ' '
DETERMINE_LOOP_INDEX = ' '

TABLES

DYNPFIELDS = t_dyn

EXCEPTIONS
INVALID_ABAPWORKAREA = 1
INVALID_DYNPROFIELD = 2
INVALID_DYNPRONAME = 3
INVALID_DYNPRONUMMER = 4
INVALID_REQUEST = 5
NO_FIELDDESCRIPTION = 6
INVALID_PARAMETER = 7
UNDEFIND_ERROR = 8
DOUBLE_CONVERSION = 9
STEPL_NOT_FOUND = 10
OTHERS = 11

IF SY-SUBRC <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

Hi,

Check this code..

PARAMETERS: p_werks TYPE werks_d,

p_lgort TYPE t001l-lgort.

AT SELECTION-SCREEN ON p_lgort.

DATA: itab LIKE dynpread OCCURS 0 WITH HEADER LINE.

DATA: v_prog LIKE d020s-prog.

v_prog = sy-repid.

itab-fieldname = 'P_WERKS'.APPEND itab.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

dyname = v_prog

dynumb = '1000'

TABLES

dynpfields = itab.

READ TABLE itab INDEX 1.

TABLES: t001l.

SELECT SINGLE * FROM t001l

WHERE werks = itab-fieldvalue

AND lgort = p_lgort.

IF sy-subrc <> 0.

MESSAGE e208(00) WITH 'Invalid storage location'.

Check this code -

REPORT zaktest.

tables: pa0000.

*data: t_530 type standard table of t530 with header line.

parameters : f1 type pa0000-massn,

f2 type pa0000-massg.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR f2.

data : t_dyn like DYNPREAD occurs 0 with header line.

t_dyn-fieldname = 'F1'.

append t_dyn.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

DYNAME = sy-repid

DYNUMB = sy-dynnr

TABLES

DYNPFIELDS = t_dyn.

You will get the value in t_dyn-fieldvalue.
