More info
If you search a cancelled order on the "Purchases" section, you'll notice that you can't click onto that order to see its details. You can see some details though such as the date the order was made.
To get all the details of the order, you instead need to download the Order Line Items report and just select the date (or estimated date range) the order was made.
Once you have the report open in Excel (or a similar application) you can locate the order and its details.
