[Dialog Programming] Field entry suggestion

Former Member — Wed, 19 Dec 2007 05:52:30 GMT

Hello SAP ABAP Experts,

We have a requirement to modify a customized screen program in such a way that when a user selects an entry in a dropdown list of Field A, the text of the entry will be displayed in Field B as a suggestion. Field B should still be editable for the user. We have tried incorporate this requirement in PAI but there are several required fields in the screen. The text will only be displayed in Field B once the user fills up the required fields and hits the enter key. Is there another way to incorporate this functionality by displaying the text first in Field B before filling up the required fields?

Thanks in advance!

Best regards,

Ann

PROCESS ON VALUE-REQUEST

FIELD list MODULE fill_list_100

FIELD list MODULE fill_list_100 INPUT

SELECT f1 f2 FROM table INTO int

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'input/output screen field'

value_org = 'S'

TABLES

value_tab = itab "it contains 2 fields that will be shown in the list box

EXCEPTIONS

parameter_error = 1

no_values_found = 2

OTHERS = 3.

IF sy-subrc <> 0.

...

ENDIF.

ENDMODULE.

VALUE LIST CREATED IN PBO

In this method we set the value list attribute to 'A'.The value list will be filled in the PBO by using FM VRM_SET_VALUES .

TYPE-POOLS : VRM

DATA : field_id TYPE VRM_ID ,

values TYPE VRM_VALUES,

value LIKE LINE OF values.

PROCESS BEFORE OUTPUT

MODULE list_fill_100

MODULE list_fill_100 OUTPUT

SELECT f1 f2 f3 FROM tab WHERE condition.

value-KEY = f1.

value-TEXT = f2

APPEND value TO VALUES

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = 'i/o screen field'

values = values.

ENDMODULE.

LIST BOX with Selection Screen

For this the FM VRM_SET_VALUES is used to fill the value table and is passed to the parameter created with TYPE LISTBOX in the selection screen event

AT SELECTION-SCREEN.

PROGRAM zlist

TYPE-POOLS : VRM.

DATA: param TYPE vrm_id,

values TYPE vrm_values,

value LIKE LINE OF values.

PARAMETERS: p_name(10) AS LISTBOX VISIBLE LENGTH 10.

AT SELECTION-SCREEN OUTPUT.

param = 'P_NAME'.

value-key = '1'.

value-text = 'JOHN'.

APPEND value TO values.

value-key = '2'.

value-text = 'PETER'.

APPEND value TO values.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING id = param

values = values.

Hi,

Initially keep the default values to all the fields then give the chance to user to edit that may solve ur problem.

Reward points if it helps.
