When running the Resource Time Summary and Detail Report from PPM Reports and Jobs the report is produces as .pdf and link are not provided on the Summary to link to the Detail.
This was reported as defect DE38742 "Drill down link not available when report is exported."
This happens in both Advanced Reporting as well as running from PPM Reports and Jobs.
In PPM Reports and Jobs page your only options are to open in an exported format vs. actual Advanced Reporting Jaspersoft report.
At this time, the reports are not coded to pass hyperlinks to an exported format. You will need to run reports separately.
For example the report Resource Time Summary and Detail will need to be run as two different reports as the exported versions are not currently coded to pass the parameters from the main report to the detail report.
