When attempting to open a report on an Execution via Monitoring/Executions (not Last Report) the following error is generated:
Read permissions for reports is missing.java.lang.RuntimeException
Review of the user shows that P permissions are present for both JOBS and REPORTS that would be referenced in this case.
Release : 12.2
Component : AUTOMATION ENGINE
The recommended resolution would be to upgrade both the AE and AWI to the latest version.
As a workaround, in your usergroup/user add an entry for CLNT, *, with P permission checked.
