Need some suggestion

I have a stored procedure to retrieve records from a database, each record contains the following fields: merchant_id, shop_id, shop_sales_amount

each merchant can have several shops and the corresponding shop_sales_amount

the format of the report(detail section) is like this:

merchant1 $10000
merchant1-shop1 $5000
merchant1-shop2 $5000
merchant2 $1000
merchant2-shop1 $500
merchant2-shop2 $500
merchant3 $100
merchant3-shop1 $50
merchant3-shop2 $50
.....

merchant1 is group 1, merchant 2 is group 2, merchant 3 is group 3...etc, the amount following the merchant name is the total sales amount of each shop under the merchant, the ordering of the group is in descending order of this total sales amount...

It is quite complicated, seriously need some suggestions or hints, I am quite new to crystal reports. Hope someone could help me out, thanksSo you should create two Crystal report groups, Merchant (#1) and Shop (#2), an order on descending sales amount beneath these (using the record sort expert). Insert the sum of the sales amount grouped at the shop level (Insert Summary, field to summarize: shop_sales_amount; calculate this summary: Sum; summary location: group 2) and move from the group2 footer to the header.

Viola! (if I understand you correctly.)sql
