You can use 'DYNP_VALUES_READ' to read selection screen values.

sample code -

it_dynpfields-fieldname = name. "-> select option to read

APPEND it_dynpfields.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

dyname = sy-cprog

dynumb = sy-dynnr

start_search_in_current_screen = 'X'

TABLES

dynpfields = it_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

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.

Field-Symbols : <fs> type any.

Assign l_fieldaname to <fs>.

Hi,

Yes it is possible to check whether teh field is initial or not.

If field1 is the name of your screen element then try teh following logic:

Loop at screen.

if field1 is initial.

< required logic>

endif.

endloop.

Hope this will help.

but i8n this case.. field1 will be having the name of the screen field right? i need to check if the value in that field is initial? Do i have to change the type of field1 to some predefined type. Mine is char now, so it will have the name of the screen field.

2. expand abap dictionary, fields....

3. Enter this discription in Field description filed in the screen...

4. Excute...

YOu can get all the field and table name...

hi Suzie,

Can you reply me in detail.

there is one function module to read dynmaic value of field.

function module name : DYNP_VALUES_READ'

by this you cam get value in internal table it_dynpred.

you have to declare this things in top ...

DATA: IT_DYNPREAD TYPE STANDARD TABLE OF DYNPREAD,

WA_DYNPREAD LIKE LINE OF IT_DYNPREAD.

example.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

DYNAME = PROGNAME

DYNUMB = DYNNUM

TABLES

DYNPFIELDS = IT_DYNPREAD

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.

READ TABLE IT_DYNPREAD WITH KEY FIELDNAME = 'ZINCHILD-INCOMPCODE'

INTO WA_DYNPREAD.

CHECK SY-SUBRC = 0.
