Get runtime screen field value

Former Member — Tue, 13 Feb 2007 17:24:40 GMT

I need to get a screen field value at runtime

I tried to use LOOP AT SCREEN statement, but i have only the name, groups, input/output, ... attributes of screen fields

i saw some post in this forum, their suggest some FM like F4IF_INT_TABLE_VALUE_REQUEST and FC_SET_DYNPRO_GET_VALUES, but does not work for me.

How I can get the value?

Thanks

Try using the FM DYNP_VALUES_READ

Thanks,

Hi,

In the AT selection screen event you need to use this code, if you are working with screens then use it in PAI

CALL FUNCTION 'DYNP_VALUES_READ'
       EXPORTING
            dyname             = progname
            dynumb             = dynnum
            translate_to_upper = 'X'
       TABLES
            dynpfields         = dynpro_values.

Regards

Sudheer

Local internal table for screen fields

data: begin of i_dynpfields occurs 0.

include structure dynpread.

data: end of i_dynpfields.

clear i_dynpfields.

refresh i_dynpfields.

i_dynpfields-fieldname = 'RD_ASERV'.

append i_dynpfields.

call function 'DYNP_VALUES_READ'

exporting

dyname = sy-cprog

dynumb = sy-dynnr

tables

dynpfields = i_dynpfields

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

others = 10.

if sy-subrc <> 0.

message i398 with 'Unable to read the selection screen values'(003).

else.

read table i_dynpfields index 1.

if sy-subrc = 0.

move i_dynpfields-fieldvalue to rd_aserv.

endif.

Award points if it helps.
