Problem: you want to restrict user from using certain Select-Options features.

Solution: you can achieve this by a simple code in the right place.

Below code presents an example of disallowing user to choose certain features from Select-Options field called S_PARAM. In this case user will be allowed to choose only the „between” and „equal” type values for the field. If you want this to work for the Selection Screen

  type-pools:
    abap.

  data:
    ls_ass type sscr_ass,
    ls_options type sscr_opt_list,
    ls_restrict type sscr_restrict.

  ls_options-name = 'S_PARAM'.
  ls_options-options-bt = abap_true.
  ls_options-options-eq = abap_true.
  append ls_options to ls_restrict-opt_list_tab.

  ls_ass-kind = 'S'.
  ls_ass-name = 'S_PARAM'.
  ls_ass-sg_main = 'I'.
  ls_ass-sg_addy = ' '.
  ls_ass-op_main = 'S_PARAM'.
  append ls_ass to ls_restrict-ass_tab.

  call function 'SELECT_OPTIONS_RESTRICT'
    EXPORTING
      restriction            = ls_restrict
    EXCEPTIONS
      too_late               = 1
      repeated               = 2
      selopt_without_options = 3
      selopt_without_signs   = 4
      invalid_sign           = 5
      empty_option_list      = 6
      invalid_kind           = 7
      repeated_kind_a        = 8
      others                 = 9.

You need to put this code in the INITIALIZATION or AT SELECTION SCREEN OUTPUT event, for it to work for Selection Screen.
