i want the rows with acatg_type = 'I' to be displayed first.
Sorry for not attaching the complete SQL, but no issues if at all required, i can do that as well.
Since its a long in-line view created SQL. thought the solution might come out showing this much part only.
i am using Report 6i on 10g.
Please help me.

Thanks Arif,,
Grouping/Break i need to be done with EXPN_CATG-within-ACATG_TYPE.
if you can view the my report image links, u'll understand much better.
EXPN_CODE is not part of the Group Fields.
Still i tried re-arranging Group fields, but still the same..
Row with ACATG_TYPE = 'I' is not moving up.
Please suggest..
