The value in the Report Timeout Seconds, specifies how long the report will run in seconds before it makes the user report fail if it encounters an issue to prevent endless waiting times.
This is a mandatory field and when a new report is created from scratch, the value is defaulted to 120 seconds. Click on Edit Details to change the Report Timeout Seconds value.
The default value for the Report Timeout Seconds field for new report can be optionally specified as a system preference called User Report Time Out Default and the code is URDEFTOSEC.
There is also a timeout maximum that can be set as a system preference called User Report Maximum Time Out seconds and the code is URMAXTOSEC. This puts an upper limit on what the user can enter as a timeout for a user report and imposes a validation error if the user enters a value greater than the value specified in this system preference.
