I ran into this problem today as well. It seems that there are no transaction IDs involved with recurring payments but instead it uses another variable called profile ID. I tried subscribing and cancelling multiple times and it generated unique ID results so I'm pretty sure that is the unique identifier. I'm assuming this is done so that you don't a new transaction ID recurring period and that it always refers to the same subscription (profile) ID.
