Hi Geoff.

If you want the query to work in versions later than 7 without setting "backward compatible" on, ammend your query as follows:

SELECT cnt(wo_itemno) as items, i_key, t_key, contractor ;
  FROM v_woitems ;
  INTO CURSOR tWoinvcont ;
  ORDER BY t_key ;
  GROUP BY t_key, i_key, contractor

All of the items in the SELECT statement except for the fields being aggregated need to be in the group by clause.
