Restricting Parameter Values

Former Member — Fri, 23 Mar 2007 16:56:59 GMT

Hi Guys/Dolls

I want to declare a parameter in my program that when the program runs the user can only pick certain values and I can then use the value in my program.

Just like a combo-box or drop down list.

How do I do this - small snippet of code would be useful.

Many thanks in advance.

Raj

Try this.

  PERFORM f4_value_request.

Hi Srinivas

This seems exactly what I want but can you tell me how I get my chosen value out? I've ran this through the debugger but can't see it.

Basically I want to print it, after I have selected it.

Use LISTBOW

TYPE-POOLS: VRM.

DATA: NAME  TYPE VRM_ID,
      LIST  TYPE VRM_VALUES,
      VALUE LIKE LINE OF LIST.

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

AT SELECTION-SCREEN OUTPUT.

NAME = 'PS_PARM'.

VALUE-KEY = '1'.
VALUE-TEXT = 'LINE 1'.
APPEND VALUE TO LIST. 

VALUE-KEY = '2'.
VALUE-TEXT = 'LINE 2'.
APPEND VALUE TO LIST.

CALL FUNCTION 'VRM_SET_VALUES' EXPORTING ID = NAME VALUES = LIST.

Hi,

The function module SELECT_OPTIONS_RESTRICT can be used for restricting possible selection options and signs. By calling this function module, we can restrict the number of selection options available for a field. For more information, refer to the function module documentation.

The code was written in 4.6C.

Code

REPORT selectoptionsrestrict.

Include type pool SSCR

TYPE-POOLS sscr.

TABLES :

marc.

defining the selection-screen

select-options :

s_matnr for marc-matnr,

s_werks for marc-werks.

Define the object to be passed to the RESTRICTION parameter

DATA restrict TYPE sscr_restrict.

Auxiliary objects for filling RESTRICT

DATA : optlist TYPE sscr_opt_list,

ass type sscr_ass.

INITIALIZATION.

Restricting the MATNR selection to only EQ and 'BT'.

optlist-name = 'OBJECTKEY1'.

optlist-options-eq = 'X'.

optlist-options-bt = 'X'.

APPEND optlist TO restrict-opt_list_tab.

ass-kind = 'S'.

ass-name = 'S_MATNR'.

ass-sg_main = 'I'.

ass-sg_addy = space.

ass-op_main = 'OBJECTKEY1'.

APPEND ass TO restrict-ass_tab.

Restricting the WERKS selection to CP, GE, LT, NE.

optlist-name = 'OBJECTKEY2'.

optlist-options-cp = 'X'.

optlist-options-ge = 'X'.

optlist-options-lt = 'X'.

optlist-options-ne = 'X'.

APPEND optlist TO restrict-opt_list_tab.

ass-kind = 'S'.

ass-name = 'S_WERKS'.

ass-sg_main = 'I'.

ass-sg_addy = space.

ass-op_main = 'OBJECTKEY2'.

APPEND ass TO restrict-ass_tab.

CALL FUNCTION 'SELECT_OPTIONS_RESTRICT'

EXPORTING

restriction = restrict

EXCEPTIONS

TOO_LATE = 1

REPEATED = 2
