hi folks,
I have a question in the use of 'parameters' syntax for the selection screen.
parameters: adpcc like z5uff-adpcc obligatory.
and I need to have only 4 values in the option 'A1' ,'A2','A3' and 'A4'. By default that field has several values from the drop down list.
I need to restrict it to these four valuesout of that drop down list.
How can I do that?
Thanks in advance
Santhosh.

Create a Custom data element and domain and assign all those 4 values at the domain level under value tab.
Then use the custom element with the parameter.
parameters: adpcc type <CUSTOM ELEMENT> obligatory.
Now if you press drop down you will get only 4 values which you have mentioned at domain level.

You can use the AT SELECTION-SCREEN ON VALUE-REQUEST event & put your validation there..

Hi vinu,
LIST BOX in SELECTION SCREEN
List Box is created in selection screen using PARAMETERS statement
with AS LISTBOX addition other attributes like VISIBLE LENGTH (width of listbox)
can be specified with the declaration.
PARAMETERS name(n) AS LISTBOX VISIBLE LENGTH n.
Here n is an integer and name is the name of parameter.
To populate the value list we use the FM VRM_SET_VALUES and the
selection screen event AT SELECTION-SCREEN OUTPUT is used to write the code to fill it.
VRM_SET_VALUES
The function module VRM_SET_VALUES is used to fill the value list associated with a List Box .This FM uses types which are declared in type group VRM. So
we should declare TYPE-POOLS VRM before using this FM.
Some important types declared in the VRM type group are
VRM_ID
It refers to the name of the input/output field associated with list box
VRM_VALUES
It refers to the internal table consisting of two fields TEXT(80C) and KEY(40)C
that will be used to create the list values.
CALL FUNCTION 'VRM_SET_VALUES'
EXPORTING
ID = name of screen element ,it is of TYPE VRM_ID
VALUES = internal table containing values,of TYPE VRM_VALUES
LIST BOX with value list from input help
In this example the screen element attribute value list is set to blank as such the value list will be filled with the 1st column of the input help,We use PROCESS ON VALUE-REQUEST event to pass the value list to the listbox.In the MODULE call used to fill the value list we can use FM like F4IF_INT_TABLE_VALUE_REQUEST to create input help as explained in the input help.The value of first column will be shown in the field when selected.
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.
award with points if helpful.

keerthi.

Hi Vinu,
I have answered this question before...
Please have a look at
In your case,
data: itab like table of z5uff-adpcc,
wa_itab like line of itab.
wa_itab = 'A1'.
append wa_itab to itab.
wa_itab = 'A2'.
append wa_itab to itab.
wa_itab = 'A3'.
append wa_itab to itab.
wa_itab = 'A4'.
append wa_itab to itab.
CALL FUNCTION 'VRM_SET_VALUES'
EXPORTING
id = adpcc
values = itab.
Hope that helps.
Regards,
Tanveer.

Hi,
or you can provide a DROP DOWN LIST for this parameter instead of asking user to enter the value.
i mean you will code such a way that user can see only the given 4/5 values & can select among one.
check the below link of how to do DROP DOWN LIST BOX, as this way we can avoid creating of another domain for this particular purpose. check this out.
