* Select TOQtemp
* Goto Top
* Those two lines are superfluous. A SELECT SQL query opens the table in
* the FROM * clause and reads it straight from the harddisk.

 
Select field1, field2,P_ID,;
 Cast(Sum(field4) As N(12,2)) As item1,;
 CAST(Sum(field5) As N(12,2)) As item2,;
 CAST(Sum(field6) As N(12,2)) As Total;
 FROM TOQtemp ; 
 Group By P_ID, field1, field2
 Browse

Note 
* Select field1, field2, P_ID
* Group By P_ID, field1, field2 
* Same columns in SELECT and GROUP BY lists. 
* The rest of the columns are all SUM() aggregations.
* You cannot SELECT nor GROUP BY a column that is aggregated in a SUM()
