Issue:

One project generates a 'System error. Contact system administrator' when clicking on the Task, Resource Utilization link, why?

Cause:

Open the 'app-ca.log' file and look for the full description of the generic 'System error' message.  In this case, you are looking for a line item that is generated near the date/time you experienced the issue for an 'action' that relates to the Task Resource Utilization page.

The message found for this issue indicates a null value on a field for the task.

Log File Error Message:
ERROR 2015-10-13 12:24:39,800 [ApplicationServerThread] niku.xql2 (admin:15735185__73cc11:projmgr.taskResUtilListReturn) Internal Processing exception
java.lang.NullPointerException

Resolution:

Either the 'Deleted Task' or 'Unplanned Task' phase has a null start or finish date.
Open the project in a scheduler (Open Workbench or MSP) and save it back. This will populate the missing date field.

Additional Information:

If you encounter a similar 'System error' generic message and the full error message in the log file is not the same, contact CA Technical Support for assistance in resolving your issue.
