Ssrs linked reports not updating
The report that you choose determines the linked report content and layout.
A linked report is a report server item that provides an access point to an existing report.
Conceptually, it is similar to a program shortcut that you use to run a program or open a file.
A linked report is derived from an existing report and retains the original's report definition.
The layout and the data source of the report cannot be changed.
The remainder of the report level settings can be individually configured on each report.
