Welcome to SDN forum

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.

See the following ex:

END OF TY_MBLNR.

DATA: IT_MBLNR TYPE STANDARD TABLE OF TY_MBLNR WITH HEADER LINE.

data: it_ret like ddshretval occurs 0 with header line.

At selection-screen on value-request for s_mat-low.

Select MBLNR from mkpf into table it_mblnr.

Hi Caro,

Check the below code.

First you need to enter the company code using f4 help.

Based on that the <b>bwkeys</b> of that company code will be populated to your next field called bwkey. Now you can see only those <b>bwkeys</b> of the entered company code.

tables: t001k.

For Identification Number

DATA: BEGIN OF it_bwkey OCCURS 0,

bwkey LIKE t001k-bwkey,

END OF it_bwkey.

data: v_bukrs(4).

For Run date

DATA: BEGIN OF it_bukrs OCCURS 0,

bukrs LIKE t001k-bukrs,

END OF it_bukrs.

DATA it_ret LIKE ddshretval OCCURS 0 WITH HEADER LINE.

SELECTION-SCREEN: BEGIN OF BLOCK main WITH FRAME TITLE text-001.

SELECTION-SCREEN SKIP.
