F4 IN MODULE POOL

[Former Member]

I want to give F4 for a field in the Module Pool.Can someone tell me how to do that??

Hi

See this and do any one of as per your requirement

For F4 Values on Screen:

PROCESS ON VALUE_REQUEST

using module call starting with FIELD i.e FIELD field MODULE module

There are number of function modules that can be used for the purpose, but these

can fullfill the task easily or combination of them.

DYNP_VALUE_READ

F4IF_FIELD_VALUE_REQUEST

F4IF_INT_TABLE_VALUE_REQUEST

POPUP_WITH_TABLE_DISPLAY

DYNP_VALUE_READ

This function module is used to read values in the screen fields. Use of this

FM causes forced transfer of data from screen fields to ABAP fields.

There are 3 exporting parameters

DYNAME = program name = SY-CPROG

DYNUMB = Screen number = SY-DYNNR

TRANSLATE_TO_UPPER = 'X'

and one importing TABLE parameter

DYNPFIELDS = Table of TYPE DYNPREAD

The DYNPFIELDS parameter is used to pass internal table of type DYNPREAD

to this FM and the values read from the screen will be stored in this table.This

table consists of two fields:

FIELDNAME : Used to pass the name of screen field for which the value is to

be read.

FIELDVALUE : Used to read the value of the field in the screen.

e.g.

DATA: SCREEN_VALUES TYPE TABLE OF DYNPREAD ,

SCREEN_VALUE LIKE LINE OF SCREEN_VALUES.

SCREEN_VALUE-FIELDNAME = 'KUNNR' . * Field to be read

APPEND SCREEN_VALUE TO SCREEN_VALUES. * Fill the table

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

DYNAME = SY-CPROG

DYNUMB = SY-DYNNR

TRANSLATE_TO_UPPER = 'X'

TABLES

DYNPFIELDS = SCREEN_VALUES.

READ TABLE SCREEN_VALUES INDEX 1 INTO SCREEN_VALUE.Now the screen value for field KUNNR is in the SCREEN_VALUE-FIELDVALUE and can be used for further processing like using it to fill the internal table to be used as parameter in F4IF_INT_TABLE_VALUE_REQUEST ETC.

F4IF_FIELD_VALUE_REQUEST

This FM is used to display value help or input from ABAP dictionary.We have to pass the name of the structure or table(TABNAME) along with the field name(FIELDNAME) . The selection can be returned to the specified screen field if three

parameters DYNPNR,DYNPPROG,DYNPROFIELD are also specified or to a table if RETRN_TAB is specified.

CALL FUNCTION 'F4IF_FIELD_VALUE_REQUEST'

EXPORTING

TABNAME = table/structure

FIELDNAME = 'field name'

DYNPPROG = SY-CPROG

DYNPNR = SY-DYNR

DYNPROFIELD = 'screen field'

IMPORTING

RETURN_TAB = table of type DYNPREAD

.

F4IF_INT_TABLE_VALUE_REQUEST

This FM is used to dsiplay values stored in an internal table as input

help.This FM is used to program our own custom help if no such input help

exists in ABAP dictionary for a particular field. The parameter VALUE_TAB is used to pass the internal table containing input values.The parameter RETFIELD

is used to specify the internal table field whose value will be returned to the screen field or RETURN_TAB.

If DYNPNR,DYNPPROG and DYNPROFIELD are specified than the user selection is passed to the screen field specified in the DYNPROFIELD. If RETURN_TAB is specified the selectionis returned in a table.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

RETFIELD = field from int table whose value will be returned

DYNPPROG = SY-CPROG

DYNPNR = SY-DYNNR

DYNPROFIELD = 'screen field'

VALUE_ORG = 'S'

TABLES

VALUE_TAB = internal table whose values will be shown.

RETURN_TAB = internal table of type DDSHRETVAL

EXCEPTIONS

parameter_error = 1

no_values_found = 2

others = 3.

POPUP_WITH_TABLE_DISPLAY

This FM is used to display the contents of an internal table in a popup window.The user can select a row and the index of that is returned in the CHOISE

parameter.The VALUETAB is used to pass the internal table.

A suitable title can be set using TITLETEXT parameter. The starting and end position of the popup can be specified by the parameters STARTPOS_COL / ROW and ENDPOS_ROW / COL .

CALL FUNCTION 'POPUP_WITH_TABLE_DISPLAY'

EXPORTING

ENDPOS_COL =

ENDPOS_ROW =

STARTPOS_COL =

STARTPOS_ROW =

TITLETEXT = 'title text'

IMPORTING

CHOISE =

TABLES

VALUETAB =

EXCEPTIONS

BREAK_OFF = 1

OTHERS = 2.

e.g.

DATA: w_choice TYPE SY-TABIX.

DATA: BEGIN OF i_values OCCURS 0 WITH HEADER LINE,

values TYPE I,

END OF i_values.

PARAMETRS : id TYPE I.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR id

i_values-values = '0001'.

APPEND i_values.

i_values-values = '0002'.

APPEND i_values.

i_values-values = '0003'.

APPEND i_values.

i_values-values = '0004'.

APPEND i_values.

CALL FUNCTION 'POPUP_WITH_TABLE_DISPLAY'

EXPORTING

ENDPOS_COL = 40

ENDPOS_ROW = 12

STARTPOS_COL = 20

STARTPOS_ROW = 5

TITLETEXT = 'Select an ID'

IMPORTING

CHOISE = w_choice

TABLES

VALUETAB = i_values

EXCEPTIONS

BREAK_OFF = 1

OTHERS = 2.

CHECK w_choice > 0.

READ TABLE i_values INDEX w_choice....now we can process the selection as it is contained

...in the structure i_values.

Other FM that may be used to provide input help is HELP_START .

HI Supriya ,

Please go through the two demo programs and you will be clear with provoding F4 help .

demo_dynpro_f4_help_dynpro

demo_dynpro_f4_help_dictionary

hope this helps ! Revert for further clarificvation if needed !

Hi,

There are two ways to show F4 help:

1. using itab 2. referring db field:

wite this codes in POV module

samels are as follows:

F4 help – using internal table example:

DATA: BEGIN OF LI_FABGRP OCCURS 0,
FABGRP LIKE ZAPO_FABGRP-FABGRP,
BEGDA LIKE ZAPO_FABGRP-BEGDA,
END OF LI_FABGRP.

DATA : T_RETURN TYPE STANDARD TABLE OF DDSHRETVAL WITH HEADER LINE,
L_RETFIELD TYPE DFIES-FIELDNAME.

parameters : S_FABGR like ZAPO_FABGRP-FABGRP.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR S_FABGR.

SELECT FABGRP BEGDA FROM ZAPO_FABGRP INTO table LI_FABGRP.

SORT LI_FABGRP BY FABGRP ASCENDING BEGDA DESCENDING.

* Henter de mulige fabriksgrupper med nyeste BEGDA *indenfor hver
DELETE ADJACENT DUPLICATES FROM LI_FABGRP COMPARING FABGRP.

L_RETFIELD = 'FABGRP'.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
EXPORTING
RETFIELD = L_RETFIELD
DYNPPROG = SY-REPID
DYNPNR = '1000'
DYNPROFIELD = 'S_FABGR'
VALUE_ORG = 'S'
MULTIPLE_CHOICE = ' '
TABLES
VALUE_TAB = LI_FABGRP
RETURN_TAB = T_RETURN
EXCEPTIONS
PARAMETER_ERROR = 1
NO_VALUES_FOUND = 2
OTHERS = 3.

F4 help – using field example:

AT SELECTION-SCREEN ON VALUE-REQUEST FOR S_FABGR.

CALL FUNCTION 'F4IF_FIELD_VALUE_REQUEST'
  EXPORTING
    tabname                   = mara
    fieldname                 = matnr
*   SEARCHHELP                = ' '
*   SHLPPARAM                 = ' '
*   DYNPPROG                  = ' '
*   DYNPNR                    = ' '
*   DYNPROFIELD               = ' '
*   STEPL                     = 0
*   VALUE                     = ' '
*   MULTIPLE_CHOICE           = ' '
*   DISPLAY                   = ' '

*   CALLBACK_FORM             = ' '
*   SELECTION_SCREEN          = ' '
* IMPORTING
*   USER_RESET                =
* TABLES
*   RETURN_TAB                =
* EXCEPTIONS
*   FIELD_NOT_FOUND           = 1
*   NO_HELP_FOR_FIELD         = 2
*   INCONSISTENT_HELP         = 3
*   NO_VALUES_FOUND           = 4
*   OTHERS                    = 5
          .

Hi,

Check the standard programs demo_dynpro_f4_help_dynpro (For the F4 obtained with our program data), demo_dynpro_f4_help_dictionary (For refering to the data dictionary fields) and demo_dynpro_f4_help_module (For the data to be displayed which we filled in an internal table).

[Former Member]

In the Data Declaration you need to declare an internal table of type DDSHRETVAL.

e.g.

DATA: intab like DDSHRETVAL occurs 0 with header line.

For F4 on a field:

PROCESS ON VALUE-REQUEST

FIELD <field-name> MODULE <module-name>.

Here, <field-name> is the name of the parameter you want to assign F4 help.

<module-name> is a module where you need to write the following code:

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

RETFIELD = <value-table field whose value will be displayed in F4>

DYNPPROG = SY-CPROG

DYNPNR = SY-DYNNR

DYNPROFIELD = <screen-field name>

VALUE_ORG = 'S'

TABLES

VALUE_TAB = <value-table>.

RETURN_TAB = internal table of type DDSHRETVAL.

Hi,

Check the following code:

AT SELECTION-SCREEN ON VALUE-REQUEST FOR S_WERK-LOW.

REFRESH ITEMP.

CLEAR ITEMP.

SELECT WERKS

NAME1

FROM T001W

INTO TABLE ITEMP

WHERE IWERK = 'M011'.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

• DDIC_STRUCTURE = ' '

RETFIELD = 'WERKS'

• PVALKEY = ' '

• DYNPPROG = ' '

• DYNPNR = ' '

• DYNPROFIELD = ' '

• STEPL = 0

• WINDOW_TITLE =

• VALUE = ' '

VALUE_ORG = 'S'

• MULTIPLE_CHOICE = ' '

• DISPLAY = ' '

• CALLBACK_PROGRAM = ' '

• CALLBACK_FORM = ' '

TABLES

VALUE_TAB = ITEMP

• FIELD_TAB =

RETURN_TAB = T_RETURN

• DYNPFLD_MAPPING =

• 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.

S_WERK-LOW = T_RETURN-FIELDVAL.

Hope this helps.

reward if helpful.
