Display all orders in which a certain product was purchased - Crystal Reports - crystal-reports

Question

I've searched all over many sites today and I am unable to find an answer to this. I am trying to display all orders in which a certain product (scarf) was purchased. For Example:
Order #1
Hat $3.00
Scarf $5.00
Order #2
Puzzel $2.00
Order #3
Scarf $5.00
With this example, I'd like to display records #1 and #3, in which a scarf was purchased, but also include "Hat" that was purchased along with the scarf in Order #1...(while excluding Order #2)
Output should be:
Order #1
Hat $3.00
Scarf $5.00
Order #3
Scarf $5.00
I've tried using instr functions to filter this information out, as well as looks for various formulas, but I cannot seem to figure this out. I appreciate everyone's time!

Answer 1

Create a SOL-expression field:
// {%order_has_scarf}
// assumes table in main report is `orders`
(
SELECT count(1) total
FROM orders o
WHERE o.order_id = orders.order_id
)
Alter record-selection formula:
AND {%order_has_scarf} > 0

Answer 2

Create a group of orders first then place the fields in detail (Hat..etc) and write a supress condition for detail and group like:
if Order="PUZZEL"
then true
else false
with this condition if puzzel is encountered then both detail and group are supressed.

Answer 3

Thanks everyone, i actaully figured out how to do this. I added another instance of the Order Details table to my crystal report, then I filtered that table by the Item ID related to the scarf, then linked that to the original order table...that way, only orders containing this particular Item ID would be passed to the original table.
Hope this makes sense!
