Dostats error

I am getting the following error while running dostats: sis_trades(MEDIUM)...SUCCESSFUL :(0 hrs 0 mins 2.129 Secs) history_id(HIGH)... Cannot Update statistics for table: sis_trades, column history_id; SQLCODE = -352, ISAM = 0, POS = 46 The column history_id is not part of the sis_trades table. We are running IDS 7.31.UD1 on Sun Solaris 6. Any ideas on this would be appreciated. Thanks Dale R.
