In all of Adobe's documentation, they state that TransactionID's must be unique. But they also state that if multiple TransactionID's are uploaded during the same visit, the snapshot that will be saved is of the last TransactionID uploaded.
So my question is, if we upload the same TransactionID across multiple visits. When we upload offline events to that TransactionID, will the events be tied back to multiple visits, and if this is the case, would uploading $25 of revenue end up showing up as $100 if it ends up being tied to 4 visits with the same Transaction ID? Or would the offline events just be attributed to the most recent visit with that Transaction ID?
The reason we need to know is that we are using our in-app user ID as the transactionID, and while we could pre-pend the userID with a unique event identifier to keep the transacitonID unique, our app data that we are uploading to analytics will not have access to that unique event identifier, so we will only be able to upload the in-app user ID to adobe as the transactionID.
