Use the FM to refresh the selection screen variable

DYNP_VALUES_READ

Hi Ramesh..

This is bcoz the Values of the Screen Fields are copied only durin PAI Event.

But if you want to READ the Values of Screen fields in POV itself .. you have to call the FM DYNP_VALUES_READ.

Check this example.

**In Top include

DATA: BEGIN OF help_item OCCURS 0,

posnr TYPE vbap-posnr,

matnr TYPE vbap-matnr,

arktx TYPE vbap-arktx,

END OF help_item.

DATA: dynfields TYPE TABLE OF dynpread WITH HEADER LINE.

• In POV Module

dynfields-fieldname = 'P_VBELN'.

APPEND dynfields.

**Read the Values of the SCREEN FIELDs

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

dyname = sy-cprog

dynumb = sy-dynnr

translate_to_upper = 'X'

TABLES

dynpfields = dynfields

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.

**Find out the Value of P_VBELN

READ TABLE dynfields WITH KEY fieldname = 'P_VBELN'.

p_vbeln = dynfields-fieldvalue.

**Convert the Value into internal format

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'

EXPORTING

input = p_vbeln

IMPORTING

output = p_vbeln.

**Fetch the correponding itemnos from VBAP

SELECT posnr matnr arktx INTO TABLE help_item

FROM vbap

WHERE vbeln = p_vbeln.

**Generate the F4 help with internal table values

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'POSNR'

dynprofield = 'P_POSNR'

dynpprog = sy-cprog

dynpnr = sy-dynnr

value_org = 'S'

TABLES

value_tab = help_item.

DYNP_VALUES_READ is the function module which reads the selection screen contents with out pressing enter. so this solves ur purpose.
