Yes, it makes sense. :-)

>Hi Timothy,

>Here's sample code that shows the porblem. As you can see with the same data but ordered differently you get different result. For detail=1, in case #1 noun='C', for case #2 it's 'A'.

SET ENGINEBEHAVIOR 70

>CREATE CURSOR bsyear03 ( ;

>INSERT INTO bsyear03 VALUES( 1, "A", 10)
>INSERT INTO bsyear03 VALUES( 1, "B", 20)
>INSERT INTO bsyear03 VALUES( 1, "C", 15)
>INSERT INTO bsyear03 VALUES( 2, "D", 30)
>Select detail, noun,  sum(quantity) ;
>  from bsyear03 group by detail

>>Sergey, to make it more meaningful perhaps I would do this....
>>select detail,noun,sum(price),sum(quantity) from s:bsyear01 group by detail;
>>into cursor curs_abc
>>INDEX On noun TO e:f
>>copy to curs_xyz
>>brow
>>I see what you mean that the noun would be meaningless because only 1 record(noun) would show up for all records matching a certain detail.
