Hi,

POV triggers on pressing of F4 Button.use the MODULE statement together with the FIELD statement and use the FM F4IF_INT_TABLE_VALUE_REQUEST.

PROCESS BEFORE OUTPUT.

MODULE STATUS_9000.

PROCESS AFTER INPUT.

MODULE USER_COMMAND_9000.

PROCESS ON VALUE-REQUEST.

FIELD CARRID MODULE GET.

MODULE GET INPUT.

select carrid from sflight into table itab UP TO 10 rows.

  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

  EXPORTING

    DYNPPROG               = SY-CPROG

    DYNPNR                    = SY-DYNNR

    RETFIELD                  = 'CARRID'

    VALUE_ORG              = 'S'

    DYNPROFIELD          = 'CARRID'

  TABLES

    VALUE_TAB              = itab.

ENDMODULE.

hi,

i tried this but its not trigerring, in debugging mode pai is trigerring after that its going to pbo but its not trigerring pov.

[former_member220538]

Hi,

FIELD CARRID MODULE GET.

Here CARRID is the screen fields name ie the name given for the field in the Layout.Click the search help associated with this field.Put a BREAK POINT in the POV Module ie in the above example GET Module and check it is triggered or not.

Hi

Please share your PAI,PBO,POV code. Please note that screen field name and field name in POV module should be same.

POV will trigger only with the attached field related activity

Use CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST' to bring search help to that field.

And test it by clicking on the search help button that comes at runtime.

Hi vinodh mohan

See this demo program for better under standing of POV

DEMO_DYNPRO_F4_HELP_MODULE

[Former Member]

Hii Vinodh,

First declare a internal table in your TOP include and for EVENT PROCESS ON VALUE-REQUEST , write it in PAI after User_command module.

Here is example,

Top Include:

DATA t_sflight TYPE STANDARD TABLE OF SFLIGHT.

PROCESS AFTER INPUT.

   MODULE user_command_9000.

   PROCESS ON VALUE-REQUEST.

     FIELD carrid MODULE f4_help.

MODULE f4_help.

     SELECT *

          FROM SFLIGHT

          INTO TABLE T_SFLIGHT

          UPTO 200 ROWS.

     IF SY_SUBRC EQ 0.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

     EXPORTING

       dynpprog        = sy-repid

       dynpnr          = sy-dynnr

       dynprofield     = 'CARRID'

       value_org       = 'S'

     TABLES

       value_tab       = t_sflight

     EXCEPTIONS

       parameter_error = 1

       no_values_found = 2

       OTHERS          = 3.

   IF sy-subrc <> 0.

*     *implement error here

   ENDIF.

     ENDIF.

ENDMODULE.

Does it give you some dump when you press F4 on field 'IT_ZPP-MATNR' if yes then do as follow.

CALL

FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

* ddic_structure = 'MARA' -------------Comment this

RETFIELD = 'MATNR'

DYNPPROG = SY-REPID

DYNPNR = SY-DYNNR

DYNPROFIELD = 'IT_ZPP-MATNR''

VALUE_ORG = 'S'


TABLES

VALUE_TAB = IT_MARA

RETURN_TAB = T_RETURN

EXCEPTIONS

PARAMETER_ERROR = 1

NO_VALUES_FOUND = 2

OTHERS = 3

[nabheetscn]

[Former Member]

hi,

  i have written code for list box in MODULE STATUS_9100.as u stated early to comment that line.

[Former Member]

Give a try with this....

MODULE FILE_SEARCH INPUT.

DATA: BEGIN OF IT_MARA OCCURS 0,

          MATNR TYPE MATNR,

      END OF IT_MARA.

*  CLEAR WA_MARA.

DATA : T_RETURN TYPE STANDARD TABLE OF DDSHRETVAL WITH HEADER LINE,

L_RETFIELD TYPE DDSHRETVAL.

   SELECT MATNR  FROM MARA INTO CORRESPONDING FIELDS OF TABLE IT_MARA .

   SORT IT_MARA BY MATNR.

     CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

       EXPORTING

         ddic_structure = 'MARA'

         RETFIELD              = 'MATNR'

         DYNPPROG              = SY-REPID

         DYNPNR                = SY-DYNNR

         DYNPROFIELD           = 'IT_ZPP-MATNR'

         VALUE_ORG             = 'S'

       TABLES

         VALUE_TAB             = IT_MARA

         RETURN_TAB = T_RETURN

      EXCEPTIONS

        PARAMETER_ERROR        = 1

        NO_VALUES_FOUND        = 2

        OTHERS                 = 3.

       IT_ZPP-MATNR = T_RETURN-FIELDVAL.

ENDMODULE.
