My requirement is that ,in a screen i have two fields
When i select a material in the first field,
then in the second field the werks must come according to the material selected int the first field.
How can the F4 be designed for this?

hi,
in pai module
at user-command
select single maktx from mara where matnr in s_matnr. [s_matnr -> name for matnr field].
if helpful reward some points.

Hi
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 .
Reward points if useful

Hi,
If in Module pool , under POV event , u need to call the FM "'F4IF_INT_TABLE_VALUE_REQUEST'" and implement the logic as below:
If in the report program u can follow this code:
REPORT ytest_2.
PARAMETERS:
mat TYPE matnr,
wer TYPE werks_d.
data: begin of itab occurs 0,
werks type werks_d,
end of itab.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR wer.
select werks from marc into table itab where matnr = mat.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
EXPORTING
DDIC_STRUCTURE = ' '
retfield = 'WERKS'
PVALKEY = ' '
DYNPPROG = sy-repid
DYNPNR = sy-dynnr
DYNPROFIELD = 'WER'
STEPL = 0
WINDOW_TITLE =
VALUE = ' '
VALUE_ORG = 'S'
MULTIPLE_CHOICE = ' '
DISPLAY = ' '
CALLBACK_PROGRAM = ' '
CALLBACK_FORM = ' '
MARK_TAB =

value_tab = itab.
FIELD_TAB =
RETURN_TAB =
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.
Revert back if any issues,
Reward with points if helpful.

hai,
PROCESS BEFORE OUTPUT.
MODULE STATUS_0100.
module init.
PROCESS AFTER INPUT.
FIELD field1
MODULE CHANGE_VALUE1 ON INPUT. "in this u populate the field2 value based on the field1 value
FIELD field2
MODULE CHANGE_VALUE2 ON INPUT.
MODULE USER_COMMAND_0100.
module exit at exit-command.
PROCESS ON VALUE-REQUEST.
FIELD filed1 MODULE VALUE_filed1.
in MODULE VALUE_filed1.
u use this code.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

i hope this will help u.
if help ful reward points.

u can solve the problem usinf the f4if_int_table_value_request.
apart from the obligatory parameter ...u have to pass the value in the tables section for "dynp_mapping". to this pass the internal tablewith values of the fields which have to be populated when a record is selected from the hitlist.
