• Clarity PPM On Premise

Issue/Introduction

1- From Clarity Advanced Reporting (Jaspersoft),
2- Click on CAPPM / Reports / Administration and click on DWH Schema Report and run the report immediately
3- After a few mins we see the error message "Error Message There was an error on the server. Try again or contact site administrator"

Resolution

Expected Results: The error message should appear for example:  

Error during report execution
net.sf.jasperreports.governors.MaxPagesGovernorException: Report "XYZ" exceeded the limit of 1,000 maximum pages

Actual Results: "Error Message There was an error on the server. Try again or contact site administrator"

We tested with the Jaspersoft 8.1 "REPORTS SERVER PATCH 2 8.1.1_6.5.2.17 FOR CLARITY.iso" It is working as expected.
