Former Member — Wed, 23 Jan 2008 06:50:52 GMT

Hi,

I have created a screen and I place a text box and change the type into List Box. I have to display data in the list box.

The user should select the data from the list box then according to that we have to popup message.

How can add data to a list box ?

satya.

Hi,

Use FM VRM_SET_VALUES.

Check this sample code

In PBO write this code for your field

CLEAR wa_itab.

wa_itab-key = '1'.

wa_itab-text = '1'.

APPEND wa_itab TO it_itab.

wa_itab-key = '2'.

wa_itab-text = '2'.

APPEND wa_itab TO it_itab.

wa_itab-key = '3'.

wa_itab-text = '3'.

APPEND wa_itab TO it_itab.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = 'ZMATERIAL' "Here use your input box name in which you need dropdown

values = it_itab

EXCEPTIONS

id_illegal_name = 1

OTHERS = 2.

see this sample demo program also DEMO_DROPDOWN_LIST_BOX

Satish

Hi Satya,

Check the properties of the list box and then add the values in the PAI part of the screen for the list box and append the values.

Hi Satyanarayana,

In your flow logic write an event.

Process on value-request.

FIELD <b>ZTD_SUGG_DATA-ZZGRADE</b> MOUDLE VALUE_REQUEST.

In module value_request input.

SELECT FROM <DB TABLE > INTO CORRESPONDING FIELDS OF TABLE I_VALUE_TAB.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

RETFIELD = 'ZZGRADE'

DYNPPROG = 'ZTDHRMOD_SUGGESTION_DATA_ENRTY'

DYNPNR = '0200'

DYNPROFIELD = 'ZTD_SUGG_DATA-ZZGRADE'

VALUE_ORG = 'S'

TABLES

VALUE_TAB = I_VALUE_TAB

EXCEPTIONS

PARAMETER_ERROR = 1

NO_VALUES_FOUND = 2

OTHERS = 3.

IF SY-SUBRC <> 0.

ENDIF.

Hope this will help you....

Hi,

Here is a simple program to understand the concept.

report y1.

type-pools : VRM.

data : name type vrm_id,

list type vrm_values,

value like line of list.

parameters : c(10) as listbox visible length 10.

at selection-screen output.

name = 'c'.

value-key = '1'.

value-text = 'line1'.

append value to list.

value-key = '2'.

value-text = 'line2'.

append value to list.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = name

values = list

thanks,
