    Hi,

    Input help can be programmed in selection screen using event

    AT SELECTION-SCREEN ON VALUE-REQUEST FOR FIELD and for module pools in event

    PROCESS ON VALUE_REQUEST using module call starting with FIELD

    i.e FIELD field MODULE module

    There ar 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 .

    Regards,

    Jagadish
