Problem in F4 help on screen

Question

Hi ,
when i am displaying F4 help for my custom field on screen , F4 pop up is coming but when i am selecting the values no value is being displayed in the field. code is like this ::
PROCESS ON VALUE-REQUEST.
cmir_value MODULE d8010_Cmir_f4. (cmir_value is of type vbeln_va)
F4 help is like this :
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
  EXPORTING
  DDIC_STRUCTURE         = ' '
    RETFIELD               = 'VBELN_VA'
  PVALKEY                = ' '
   DYNPPROG               = sy-cprog
   DYNPNR                 = sy-dynnr          
   DYNPROFIELD            = 'CMIR_VALUE'     
   VALUE_ORG              = c_s
  TABLES
    VALUE_TAB              = it_val_f4
   RETURN_TAB              = it_ret
EXCEPTIONS
   PARAMETER_ERROR        = 1
   NO_VALUES_FOUND        = 2
   OTHERS                 = 3.
I have seen similar kind of quieries on SDN but with those answers i am not able to find any solution for my problem.
Best Regards

Answer 1

Here is the code that i am trying ::
DATA : CMIR_VALUE TYPE vbeln_va.
PROCESS ON VALUE-REQUEST.
  FIELD:  cmir_value MODULE d8010_Cmir_f4.
inside MODULE d8010_Cmir_f4...
types : BEGIN OF ty_val_f4,
         Cmirno TYPE VBELN_VA, "VBAK-VBELN, "from vbak
         Material TYPE MATNR, " from vbap
         Matentered TYPE MATWA, " from vbap
         custmatno TYPE MATNR_KU, "KDMAT
         soldto   TYPE KUNAG, " vbak-kunnr
         shipto   TYPE KUNN2, "from knvp
         shiptocountry  TYPE LAND1, "from adrc
         shippingcond  TYPE VSBED, " from vbak
         shiptoname1 TYPE AD_NAME1, "name1
         extendeddesc1 TYPE /FIR/RO2C0BGS_EXTNDDESC,   " from vbap
         extendeddesc2 TYPE /FIR/RO2C0BGS_EXTNDDESC,    " from vbap
         extendeddesc3 TYPE /FIR/RO2C0BGS_EXTNDDESC,   " from vbap
         END OF ty_val_f4.
data :  it_val_f4 TYPE STANDARD TABLE OF ty_val_F4,
          wa_val_f4 TYPE ty_val_f4,
          it_ret TYPE TABLE OF DDSHRETVAL,
          wa_ret TYPE DDSHRETVAL,
values are fetched from diff tables and it_val_f4 is formed . Now
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
  EXPORTING
  DDIC_STRUCTURE         = ' '
    RETFIELD               = 'VBELN'   (Tried with VBELN_VA also)
   DYNPPROG               = sy-cprog
   DYNPNR                 = sy-dynnr          
   DYNPROFIELD            = 'CMIR_VALUE'     
   VALUE_ORG              = c_s (that is S)
  TABLES
    VALUE_TAB              = it_val_f4
   RETURN_TAB              = it_ret
EXCEPTIONS
   PARAMETER_ERROR        = 1
   NO_VALUES_FOUND        = 2
   OTHERS                 = 3
IF SY-SUBRC <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
when i execute this code in it_ret in FIELDVAL , no vallue is populating. Hence after selecting the value in F4 popup, no value is coming in my cutom field cmir_value.
