[Florin Wach]

let's see, if you're hanging here:

*---- check authority
    IF substitute-objid NE sy-uname.
      PERFORM check_authority USING    sy-uname
                                       swrco_subst_display
                              CHANGING lv_rc
                                       ls_t100msg.
