Crystal Report row should change when two different field is changed - crystal-reports

Question

I am using crystal report 7 and the Oracle database. I have implemented the following SQL query in the crystal report:
SELECT ins.ins_name,ins.ins, SUBSTR(cardh.g_id,1,1), SUBSTR(cardh.g_id,2,2),
SUBSTR(cardh.g_id,4,2), crdi.bn,
sum(DECODE(cardh.crd_st, 'PO', 1, 0)) POCount,
sum(DECODE(cardh.crd_st, 'CN', 1, 0)) CNCount
FROM crdh, crdi, ins
WHERE crdh.crd_st IN ('PO','CN') and crdi.bn in
(select unique bn from crdh)and crdh.bn=crdi.bn and
crdi.ins=ins.ins
GROUP BY ins.ins, crdi.bn, ins.ins_name, cardh.g_id
ORDER BY ins.ins, crdi.bn;
Output of the above query:
To implement the above SQL query in Crystal Report I have made three groups on the cardh.g_id, crdi.bn, ins.ins in the same order. But Crystal report changes rows only when the cardh.g_id is changing. I want Crystal report should change rows only when the crdi.bn is also changing.
The current report is looking as follows:
The above report should be displayed as the output of the SQL query.

Answer 1

ok in this case what you need to do is to group the report as the combination of fieldds you require.
Create a formula #Grouping and write the combination something like:
ToText(cardh.g_id)+ToText(crdi.bn)+ToText(ins.ins)
Now use above formula to group the report.

Go to Record Sort Expert and select the required field then select asc or desc as per your requirement.
