Since release 6.0, Codebeamer supports issue working time recording/tracking.

This optional feature (if licensed) will be available out of the box for new projects, but has to be added manually to existing projects, that have been created with older releases.

First you have to define a Timekeeping tracker for the project (Project > Trackers > New Tracker):

Generally you should only grant the Project Admin full permissions on the Timekeeping tracker (Tracker > Configure > Permissions):

All other roles should only have permission to add new recordings and to see their own recordings.

Next make sure that all trackers, where you want to record working time, have a Spent Hours field with Sum/Total value aggregation (Tracker > Configure > Fields):

Making Spent Hours formatted will display the value as "hh:mm" instead of a decimal.

Also grant appropriate field permissions to Spent Hours (Tracker > Configure > Field Access).

Issue trackers are associated with Time Recording trackers through Subject field (property name: subjects). It is defined in the field configuration of the Time Recording tracker which trackers are logging entries to that tracker. When creating a Time Recording tracker there are already a number of tracker types added to the Subject field. This scope can be limited or extended in the Work/Config items configuration.
