Hallow I use a selection screen like that

SELECTION-SCREEN BEGIN OF BLOCK b2 WITH FRAME TITLE text-t02.

SELECT-OPTIONS c_course FOR z_course_table-objid NO INTERVALS NO-EXTENSION.

SELECTION-SCREEN END OF BLOCK b2.

And I wont that c_course will be <b>required</b>.

How can I do that.

use the option<b> obligatory</b>

I hope u are looking for that c_course as required mandatory.

Tables: z_course_table.

SELECTION-SCREEN BEGIN OF BLOCK b2 WITH FRAME TITLE text-t02.

SELECT-OPTIONS c_course FOR z_course_table-objid obligatory NO INTERVALS NO-EXTENSION.

SELECTION-SCREEN END OF BLOCK b2.

hi,

you can do this in

At selection-screen

event

eg:

report zchk.
  
selection-screen begin of block b1 with frame.
PARAMETERS : test_field(10) type c.
SELECT-OPTIONS c_course FOR z_course_table-objid NO INTERVALS NO-EXTENSION.
selection-screen end of block b1.
 
at selection-screen.
 
if test_field is initial.
message 'Enter test field' type 'E'.
endif.

if  c_course-low is initial.
message 'Enter c_course field' type 'E'.
endif.

like this u have to check c_course-high.

hope u got an idea.
