You can use at selection-screen for this purpose.

at selection-screen-output.

if p_mawerk is not initial.

endif.

Hi,

first:

you don´t declare parameters with DATA but with SELECT-OPTIONS or PARAMETERS.

second:

the system recognizes the value in P_MAWERK till you press , which is certainly a handycapp in selection screens.

documentation for AT SELECTION-SCREEN:

With the events for the field and input help, no data is transported between the selection screen and the ABAP program. As with general screens, suitable function modules must be used for these. The parameters and selection criteria changed for the input help are transported to the selection screen.

hi,

Pls check this it may help you out

at selection-screen on value-request for p_mawerk .

progname = sy-repid.

dynnum = sy-dynnr.

*The field value that is to be fetched from Selection-screen is passed to the internal table below.

field_value-fieldname = 'p_mawerk'.

append field_value to dynpro_values.

*This function module is used to read the Fiscal year from the selection screen

and to get the Document numbers only related to that fiscal year.

call function 'DYNP_VALUES_READ'

exporting

dyname = progname

dynumb = dynnum

translate_to_upper = 'X'

tables

dynpfields = dynpro_values

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.

read table dynpro_values index 1 into field_value.

select the values for the second parameter using the value in the first parameter using query into values_tab.

declare vaues_tab as you require in the search help parameters

call function 'F4IF_INT_TABLE_VALUE_REQUEST'

exporting

retfield = ''

dynpprog = progname

dynpnr = dynnum

dynprofield = 'p_workct' (Give in CAPS)

value_org = 'S'

window_title = ' '

tables

hi,

i think the following will be useful.

parameters: p_mawerk like qmel-mawerk obligatory,

p_workct like crhd-arbpl obligatory.

DATA: BEGIN OF VALUES,

mawerk type tablename-mawerk,

workct TYPE tablename-workct,

END OF VALUES.

DATA: DINPRO_VALUES TYPE TABLE OF DYNPREAD,

VALUE_TAB LIKE TABLE OF VALUES,

FIELD_VALUE LIKE LINE OF DINPRO_VALUES.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_workct.

FIELD_VALUE-FIELDNAME = 'MAWERK'.

APPEND FIELD_VALUE TO DINPRO_VALUES.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

DYNAME = SY-REPID

DYNUMB = SY-DYNNR

TRANSLATE_TO_UPPER = 'X'

TABLES

DYNPFIELDS = DINPRO_VALUES.

READ TABLE DINPRO_VALUES INDEX 1 INTO FIELD_VALUE.

VALUES-MAwerk = FIELD_VALUE-FIELDVALUE.

select mawerk workct from table name into table value_tab where mawerk eq FIELD_VALUE-FIELDVALUE.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

RETFIELD = 'WORKCT'

DYNPPROG = SY-REPID

DYNPNR = SY-DYNNR

DYNPROFIELD = 'P_WORKCT'

VALUE_ORG = 'S'

TABLES

VALUE_TAB = VALUE_TAB.

then write select query to be printed in the output.
