below is my code

* read (selected) connections
  call function 'ARCHIV_GET_CONNECTIONS_INT'
    exporting
      archiv_id                = p_arc
      NO_AUTH_CHECK            = 'X'
    tables
     connections              = l_connections
    exceptions
      nothing_found            = 1
      others                   = 2
