We are having trouble with a PI notification report. The report is set up to display values from the referenced element of an event frame. All of the values are PI point references. In a test, the report displayed the timestamp of the PI point's value, but returns Error retrieving result when the "Value at start time" attribute is put in the report.
The HTML preview of the report shows the values correctly, but the report that is emailed shows the error.
We are running PI server version 3.4.420.1182
Any suggestions on how to resolve this issue would be welcomed.
