Zoned and packed fields in query

Hi,

I have a query running over our order lines file, selecting specific items 
and the ordered quantity.
The selected records are written to a temporary file, and then copied 
(with cpyf *nochk) to the input
file of another program. This works fine. 

However, when I include level break for the item code, and sum up the 
quantity, the quantity field in
the query output file changes from packed to zoned and I get a decimal 
error when I run the program.

Is there any way around this? The input file for the program needs the 
quantity in packed decimal format.

Regards,

Oliver
