If you GROUP by order, that means they are ORDERED by that GROUP.
Do you mean that you want the details within the order sorted by description.
You keep stating that you want the impossible, you want to order by order, but order by description, please be specific.
Try Report->Sort Expert or Group Sort Expert, depending upon what you want. I think it's the same or similar in CR 9.
You might speak with your dba first and learn what a GROUP is, then this might make more sense to you.
