Data Declaration :
  I_NATIO TYPE VRM_VALUES,
  W_NATIO LIKE LINE OF I_NATIO
data: begin of itab occurs 0,
LT(10)  type c,    
end of itab.
**This query to data retrival
select  x1 x2 into table itab form tbl .
loop at itab.
w_natio-key = itab-LT.
w_natio-text = itab-LT.
append w_natio into i_natio.
clear w_natio.
endloop.
**This code  for setting values in the list box
CALL FUNCTION 'VRM_SET_VALUES'

      ID     = 'LT'
      VALUES = I_NATIO.
