I'm need to change the time period from the Workbench so that The users can see more past dates. Anyone know how you can change? Please send me the steps. If you check in Open / TimeManagement / TimeSheets / SearchTimeSheets. Please check the screenshot attached.
I would suggest to explicitly add them to server.conf, then run kUpdateHtml.sh and restart the server in order to pickup the new configuration options.
Which PPM version are you on? You might take advantage of the Administration Console web tool to change server parameters without manually editing the server.conf file (see enclosed screenshot) - some changes don't even require server restart.
