When I use Select Expert to extract data to limit the parameter of the original report, would the filters on the sub report be reflected accordingly?
No. The report generated from the Select Expert would still carry the original report’s input parameter. You may want to make some notation for the sub report to avoid confusion. Select Expert, a feature in the Crystal Offline Viewer, is available for producing report subsets. However, it is recommended that Select Expert should be reserved for more advanced users.
