I think this is a defect and you need to raise an SR. I'm able to replicate this issue and I see an obvious ramification of this. In my case, I created an autopopulated property with "copy from data page" option. The data page has internal data table as data source. I used OOTB D_pyProduct as the data page. When the case is created, based on the entered GUID, the corresponding product details are "copied" over into the case and persisted. When the product details are exposed and used in a report definition, and you run the report, the data page is reloaded. So if data in the data table was modified after it was "copied" over to the case, the RD output now shows the latest data and not the data as it was saved with the case. In other words, the behavior is the same as what you expect when you use "refer to a data page" and not "copy from data page". If you open the case from the RD output, the clipboard shows the correct, expected data. So the issue IMO is that the data page on the autopopulated property shouldn't get triggered while running the RD.
