Hi All,
I found a way where you can refresh the data but only once with CR 2013 Viewer, so every time you can only refresh once. Then you need to close the report and reopen the report. This only work with report with prompt parameter selection that required all data. When your file initially have a save report, it will display the saved report. If you change the report range to "no end", the viewer will refresh with the latest information of all range into the report.
This is not the correct feature intended by the developer but it works in a way. You may want to try and see if applicable.
