How to have logical expression with value '*' not wildcard '*'

Question

Hi ,
    I have requirement where i have to filter records based on a field with value  EQ '' but strangely it is taking wildcard '' in the production system. In the Dev system it is taken as exact value '' but behaves as a wild card in prod system. Please advice a sure shot change which will work in both the environment as i am on a strict deadline for this. Will a usage of CONSTANT work ? Constant : val   type c value "".

Hi,
Check the bellow code which will help you in using wild card in searcg help.
DATA: ls_selopt         TYPE ddshselopt,                                  
        ls_t006a          LIKE t006a.                                        
TYPES:lv_range          TYPE char45.
CALL FUNCTION 'F4UT_PARAMETER_VALUE_GET'
      EXPORTING
        parameter         = lc_old_mat
      IMPORTING
        value             = lv_dummy
      TABLES
        shlp_tab          = shlp_tab
        record_tab        = record_tab
        selopt_tab        = lt_sel_opt
      CHANGING
        shlp              = shlp
        callcontrol       = callcontrol
      EXCEPTIONS
        parameter_unknown = 1
        OTHERS            = 2.
    IF sy-subrc <> 0.
      EXIT.
    ELSEIF NOT lv_dummy IS INITIAL.
      lv_old_filled = 'X'.
    real backend system ?
      MOVE 'I'          TO ls_old_mat_ranges-sign.
      MOVE 'EQ'         TO ls_old_mat_ranges-option.
      MOVE lv_dummy(10) TO ls_old_mat_ranges-low.
      APPEND ls_old_mat_ranges TO lt_old_mat_ranges.
    ELSEIF NOT lt_sel_opt[] IS INITIAL.
      lv_old_filled = 'X'.
      LOOP AT lt_sel_opt INTO ls_sel_opt.
      no select in case of 'all systems'
        IF ls_sel_opt-low EQ '*'.
          DELETE lt_sel_opt.
        ELSE.
        wildcards
          MOVE-CORRESPONDING ls_sel_opt TO ls_old_mat_ranges.
          APPEND ls_old_mat_ranges TO lt_old_mat_ranges.
        ENDIF.
      ENDLOOP.
    ENDIF.
