There is no reason for changing /usr/tideway/data/installed/reports. This directory is considered controlled by ADDM. Do not modify or put files in this directory as an upgrade may replace/remove them. Any custom reports should be put into /usr/tideway/data/custom/reports. To access this directory you will need to log onto CLI of the appliance.
