I am facing problem with tag-history report. In history there is lot more data logged, but when report is generated it shows just one reading value at time of report generation and it repeats the same value on 30-35 pages. It doesn't shows the past 8-12 hrs reading historized in SQL DB, even though start & end date, time is defined in report. Can anyone suggest , the solution to this problem?
That usually means your row data fields have an over-specified data key. They should be just
@tablekey.column@. Dragging from the key browser creates this error.
Thanks , your solution did work well. After removal of "tablekey", now report is printing historized data for respective column.
