You can achieve the 1st requirement with

CHECK field IS INITIAL. "the check command aborts the current program flow if the field is empty.

The 2nd requirement you can achieve with something like

IF field IS NOT INITIAL.
   MESSAGE 'Socorro' TYPE 'I'. "if you want the message to be an error message, use TYPE 'E' instead.

I didn't understand exactly your 3rd requirement.

Hope this helps, anyway.

Hi,

1. To appear any value use 'defalut' in parameter statement.

2. For The second requirement 'at selection-screen', use function module 'f4if_int_table_value_requset' to get values from table and populate it in the internal table and when you enter value, check it with the values in internal table . If entered value is wrong display error message.

Hi,

As per your requirement:

1. make it Obligatory,

parameters: pa_telf1 type <xyz> OBLIGATORY.

For 2 & 3.

In event

AT SELECTION-SCREEN ON pa_telf1.

perform check_input.

**********************************************

in Form Check_input.

write the code to fetch data from the database table where you want to check its validity from.

select single <field>

from <DB table>

into g_telf1

where telf1 = pa_telf1.

if sy-subrc NE 0.

raise error message.

if u have define like this,

parameter : matnr like mara-matnr.

1. the field should not be empty

--> for this u can do like this

parameter : matnr like mara-matnr obligatory default 'ABC' .

by this u r 2nd problem also solve.

3. simply take mara table data into an one internal table say it_mara.--->

At selection-screen on output.

select * from mara into table it_mara.

and here u check u r values in parameter : matnr.

read table it_mara with key matnr = matnr.

if sy-subrc <> '0'.

Message 'Value Not found chk ur values' Type 'E'.

endif.

Sanket.

Hi,

Qustion no 1.

Solution : Use keyword OBLIGATORY.

Qustion no 2 and 3.

Solution : In ' AT SELECTION-SCREEN ', Use function module 'F4IF_INT_TABLE_VALUE_REQUEST' and get the input values and display the values in input field.

To make the field non-empty, in the parameter declaration statement add 'Obligatory' keyword. To check it in a value table, use the following statement assuming zvalue_tab is the value table and the field is telf1 in the value table.

select count(*)

from zvalue_tab

where telf1 = pa_telf1.

if sy-subrc ne 0.

'Display error message.

endif.

The above code should be written in 'at selection-screen on pa_telf1' event.
